Female and male hormones in tablet form can be implanted
subcutaneously, and in this way accurately controlled
use of the hormones over long periods is obtained
(Deanesly and Parkes, 1938; Parkes, 1938). In human
beings this method has not yet been extensively tried
(Bishop, 1938; Foss, 1939; Geist, Salmon, and Walter,
1939).
Below are given reports of twelve patients who were
given in all sixteen implantations of hormone tablets.
Female hormone was implanted in the case of two patients
and male hormone in the case of the remaining ten.
Implantation of Tablets of Oestradiol
Both of the women whose cases are here recorded had
hitherto been sterile; in both the uterus was infantile;
both desired children and had on many occasions been
treated unsuccessfully with female hormones and anterior
lobe preparations.
Case 1.-The result of the implantation was negative, as
the tablets were expelled again ten days after insertion. This
woman was very thin and had a scanty subcutaneous layer of
fat; the tablets had been implanted too near the skin.
Case 2.-The patient is 32 years of age; she did not
conceive either with her first husband or with her present one.
Mud-bath and diathermic treatment and dilatations and
curettage of the uterus were of no avail. Tubes were open.
Menstruation was regular. Uterus was very firm; measurement
with a probe gave barely two inches. After injections
of almost one million units of oestrogenic preparation during
six months the uterus became softer in consistency and its
size aiso seemed to increase, but it reverted to its old firm
consistency immediately the treatment was left off. In order
to apply continuous stimulation to the uterus, five tablets of
oestradiol were implanted deep in the subcutaneous fat of
the right hypogastric region on September 6, 1938. (Each
tablet weighed 15 mg.) The last normal menstruation
occurred on September 14, and then, as expected, menstruation
ceased. On January 1, 1939, the periods returned, and in
February and March there were haemorrhages lasting up to
three weeks. In April they increased still more, as had been
previously expected. Curetting revealed a uterus more than
three inches in length and a definite cystically proliferated
mucous membrane. The Aschheim-Zondek reaction was
negative. On May 13 that is, 249 days after the implantation
-the tablets were removed by means of a small skin incision,
and the amount of hormone absorbed was determined. Then
menstruation was again normal, the last period being on
October 4, 1939, when the uterus was the same size as during
the curetting. In November signs of pregnancy were observed,
and on the 10th of that month the Aschheim-Zondek reaction
was positive.
In March, 1940, the uterus corresponded in size to that of
a fifth-month pregnancy; the Aschheim-Zondek reaction was
again positive. The pregnancy so greatly desired by the patient
has undoubtedly been attained, so far without complications.
Implantation of Testosterone Tablets
Five women with fibroids of the uterus complicated by
menorrhagia were treated; one woman with functional
bleeding; two patients with chronically recurring mastitis
and multiple nodules in the breast; and, finally, two with
cancer of the breast, one of whom, after numerous operations
and x-ray treatment, was to be regarded as hopeless,
while the other, after a radical operation and frequent
x-ray treatment, had continual recurrences.
Case 3.-The patient, 42 years of age and childless, had
previously had a laparotomy on account of an ovarian cyst,
now a cervical fibroid larger than a fist, of intraligamentary
development. Menstruation lasted up to fourteen days, with
much flow of blood. In 1937 and 1938 1 gave her injections
with testosterone propionate and inunctions into the skin of
an alcoholic solution of the same hormone. Results were
good, but only temporary. On September 12, 1938, twelve
tablets of testosterone propionate, amounting altogether to
600 mg., were implanted. From September 2 to 16 occurred the
last profuse menstruation ; on the 24th there was a haemorrhage
lasting five days: and then there was amenorrhoea
until February 20, 1939. After that there were apparently
two very short periods, and from April to July there was
amenorrhoea. In July there was a haemorrhage lasting six
days, followed by complete amenorrhoea until the present
time, without the appearance of menopausal symptoms. The
fibrpid has not changed its size or consistency. The patient,
who had refused operation, is well satisfied with her present
condition. Time of observation after the implantation
amounts to sixteen months.
Case 4.-Patient 29 years of age. In April, 1937, I
enucleated three intramural fibroids from the retroflexed
uterus. Nevertheless menstruation remained as severe as
previously and lasted over a week; severe, at times intolerable,
premenstrual breast pains persisted. On August
19, 1938, two tablets of testosterone propionate (in all 948 mg.)
were implanted. Amenorrhoea followed. The first period
was on November 22. On November 28-that is, 101
days after the implantation the two tablets were expelled
as a result of a severe traumatic haematoma of the abdominal
wall. During the first year after the implantation periods
were normal, and there was hardly any complaint of premenstrual
breast pains. The condition of the generative
organs was normal. From October, 1939, onwards that is,
fifteen months after the implantation-the periods once again
became menorrhagic. Time of observation was eighteen
months.
Case 5.-The patient, 43 years of age, with a submucouLs
fibroid the size of a fist, had periods lasting ten days with
much loss of blood. Operation was refused. On October 15,
1938, twelve tablets of testosterone (each tablet containing
50 mg.) were implanted. On October 24 a haemorrhage
lasted ten days; after that there was amenorrhoea until
January 28. 1939. Regular periods of five days' duration
followed, the fibroid being unchanged. Last examination was
in July, 1939. Time of observation lasted nine months.
Case 6.- The patient, 40 years of age, had been previously
curetted and treated by x rays in Vienna for menorrhagia.
For some months past the periods had again been very severe,
lasting fourteen days. There were a few hard fibroids in a
uterus almost the size of a fist. Operation was refused, On
February 1, 1939, twelve tablets of testosterone (in all 600 mg.)
were implanted. There was amenorrhoea until June 5, 1939,
and after that normal five-day menstruation. Final examination
in the middle of January, 1940, revealed the fibroids the
same size as previously. Periods were normal, lasting five
to six days, and there was far less loss of blood than hitherto.
Time of observation after the implantation-nearly one year.
Case 7.-Patient 34 years of age. There was definite
masculine distribution of hair on the legs and abdomen.
Previously removal of an ovarian cyst and a fibroid had been
performed. The menorrhagia then disappeared for one year
only. Intolerable breast pains occurred one week before each
menstruation. For some months past the menorrhagia had
recurred. A small fibroid the size of a walnut could be felt
in the uterus. On May 13 386 mg. (eight tablets) of testosterone
were implanted. The breast pains disappeared
entirely but the menorrhagia was not affected ; in fact, the
impression is that the periods became still more severe. On
August 22 the uterus was curetted and the endometrium was
found to be atrophic. On the same day the implanted tablets
were removed; only three were found, and they were much
thinner and greatly reduced in size. During the next four
months the premenstrual breast pains disappeared, but the
menorrhagia had diminished by two days only, though the
loss of blood was still considerable.
Case 8.-The patient, 38 years of age, had so severe a
menorrhagia in consequence of a fibroid that she was unable
to work. On December 29, 1939, 600 mg. of testosterone
propionate were implanted. On the sixth day after this we
tried to detect the tablets in the tissue by x rays. The tablets
could not be detected with certainty, although it was thought
that some crystal-like shadows could be observed. The period
of observation is too short for account to be taken of the case
here.
Case 9.-The patient was 40 years of age, with regular
menstruation. Her mother had died of cancer of the breast.
For the last five months she had had pains in the breast and
a nodule the size of a bean could be felt in the right breast.
Histological examination revealed chronic mastitis. The
patient had had the same symptoms a year ago. On March
27, 1939, 300 mg. of testosterone were implanted. Ten days
later the breast pains disappeared. There was amenorrhoea
for six weeks, and after that the periods were normal again.
The whole of the remaining tumour had disappeared. In July,
1939, however, it was again possible to feel a small nodule
in another part of the right breast; but it had vanished in
three weeks. So far no new tumour has appeared; there are
no more pains. Time of observation after the implantation
was ten months.
Case 10.-The patient was 40 years old and her menstruation
was normal. During the last six years she had been
operated on four times on both breasts for cystic tumours.
Histological examination revealed a fibro-adenoma. For three
months before implantation she had noticed a tumour in the
right breast. It was the size of a walnut and gave rise to
-considerable pain. On September 9, 1939. 700 mg. of testosterone
(fourteen tablets) were implanted. Amenorrhoea
followed and has persisted till now (February 2.O, 1940).
Examination carried out six months after the implantation
shows that nearly the whole of the tumour has disappeared;
there is no pain. (Another very remarkable coincidence is
that the patient stated she was able to dispense with her
glasses, which she was wearing for myopia. The same
observation was made in another case in which 600 mg. of
testosterone propionate were injected.)
Case 11.-The patient was 60 years of age, and had been
treated for the last eight years with radium for carcinoma
of the breast. Multiple recurrences were treated by operation.
Metastasis now exists on both sides, supraclavicular and
mediastinal. In the right axilla there is a diffuse infiltration;
around the right nipple there is a suppurating ulcer the size
of a half-crown. The radiologist called in recommended
morphine for combating pain; on account of the disseminated
carcinosis no other treatment was carried out. On July 1,
July 14, and October 3, 1939. 1,650 mg. of testosterone
propionate in all were implanted. On October 3 two of the
tablets implanted on July 14 were removed in order to determine
the degree of absorption. The temporary result was a
superficial swelling around the right nipple, accompanied by
considerable reduction of the ulcer, a softening of the hard
infiltrations in the armpit, and also a superficial swelling and
pigmentation of the healthy breast. Striking features were an
increase in weight by 5 lb. and an obvious state of improved
health; the patient also had a certain dark pigmentation of the
face as if she had been given ultra-violet rays, and the pain
along the right arm was considerably less. This improvement
lasted only until the middle of November, when the patient's
weight again fell off, and further decline could not be checked.
Case 12.-The patient was a woman 45 years of age, who
after radical operation for cancer of the breast on the right
side and much x-ray treatment over a period of one year
showed two recurrences in the operation cicatrix. There is
now a fresh acute recurrence in the armpit. On August 22,
September 18, and November 8, 1939, 1,500 mg. in all of
testosterone were implanted. In the beginning the patient
showed similar symptoms to those described in the case of the
preceding patient, but up to January, 1940, no change in the
size or consistency of the recurring tumour in the axilla could
be found (although it did not reveal any growth), for which
reason the patient was again given x-ray treatment.
Technique of Implantation and Absorptive Powers
of the Tissues
Under a local anaesthetic an incision two to three
inches in length is made through the skin of the right or
left hypogastric region ; the fatty tissue is drawn apart,
and each tablet (which has been previously sterilized in
boiling water for three to five minutes) is embedded
separately in the subcutaneous tissue. The tablets should
not be in contact with one another and should not lie
directly beneath the skin, as otherwise they act too much
as foreign bodies and are expelled again too easily. The
deeper the tablet lies the better it will be retained; the
larger the tablet the less certain the chances of healing
up. A tablet one-third of an inch in diameter is most
suitable for implantation, although the absorption proceeds
more rapidly when the surface is larger. The skin,
and on occasion the fatty tissue (when there is a thick
layer of the latter), is closed with a few stitches of catgut.
This technique has given me the best results.
In Cases 2, 4, 7, and 11 it was possible to ascertain the
loss in weight undergone by the implanted tablets during
their retention in the body. When the tablets were removed
it was found that some were still lying free in the
fatty tissue, some were attached to the fatty tissue by
light fibrous bands, and one tablet was surrounded by a
tough fibrous layer. It will be seen from this that the
absorption need not proceed uniformly when the implanted
tablets are not lying quite free.
In Case 2 five tablets of oestradiol had been implanted,
each tablet weighing 15 mg. On removal they weighed
3.8 mg., 5 mg., 2.8 mg., 6.4 mg., and 6.5 mg. respectively.
Within 249 days, therefore, there had been a total absorption
of 50.5 mg. of oestradiol. In Case 4 there had been,
within 101 days, an absorption of 376 mg. of testosterone
propionate out of the 948 mg. implanted; in Case 7
(likewise in a period of 101 days) 368 mg. of testosterone
out of a total of 386 mg. had been lost. In Case 11 (of
carcinoma), finally, within a period of eighty-one days,
34.5 mg. had been absorbed from one of the two tablets
(each of which had weighed 48 mg.) and 34 mg. from the
other. At the beginning, when the tablet presents a large
surface, more is absorbed than later on, when the surface
of the tablet has already been considerably reduced in size.
Results of Oestradiol Implantation
As regards Case 2, in which the female hormone was
implanted, the patient reacted in the same way as the
experimental animal. The large quantity of oestradiol
depressed the function of the anterior lobe of the pituitary
gland; gonadotrophic hormones were not emitted from
the anterior lobe. Consequently maturation of ovum and
menstruation did not occur. Just as in a normal pregnancy
the function of the anterior lobe of the pituitary
gland is depressed by the oestrogenic substances produced
in the placenta, and the ovary forced into a kind of
hibernation, so in this case the same effect was produced
by the implant. Nevertheless local action of oestradiol
on the uterine muscle and mucous membrane of the uterus
became plainly visible. The uterus grew, and the mucous
membrane became converted into cystically proliferated
endometrium and was cast off gradually by haemorrhages.
After removal of the hormone tablets the anterior lobe
gradually recovered, the hibernating ovary was stimulated
by fresh gonadotrophic hormone produced in the anterior
lobe, ripening of the ovum occurred again, and hence
there was normal menstruation. The muscular apparatus
of the uterus had been substantially strengthened and was
now able to draw up the semen, which it had previously
been unable to do because of muscular deficiency. The
patient became pregnant.
Rationale of Male Hormone Therapy
French authors (Mocquot and Moricard, 1936; Capitain
and Desmarest, 1937; Turpault, 1937) were the first
to use the male hormone in gynaecological affections, but
only after the experimental investigations of Zuckermann
(1937) and my proof (1938) that a sufficiently large amount
of male hormone produces in women a temporary atrophy
of the endometrium (maintainable for a lengthy period)
and a temporary sterilization could a sure enough basis of
a quantitative character for therapy be established. Foss
(1938) in this country and, in particular, American
authors (Gaines, Geist, and Salmon, 1938) have later
confirmed this.
The endometrium is the mirror in which are reflected
the hormonal processes taking place in the ovaries. The
growth and the ripenipg of the follicle are reflected in this
mirror, as are the birth and the death of the corpus
luteum. In the same way the endometrium reflects all
the processes which occur after absorption of the implanted
artificial ovary and of the artificial testicle in tablet
form, although, of course, the artificial ovary is incomplete,
as is the artificial testicle, for each yields only a
single hormone. Both artificial glands, however, have a
common feature in that they depress the function of the
anterior lobe of the pituitary gland and reduce the secretion
of the gonadotrophic hormones, or even suppress it
entirely when the implantate is sufficiently large. In
Cases 3 and 5 the gonadotrophic hormones were examined
before and after the implantation (Dr. Wiesner), and in
the first case they disappeared entirely from the urine after
the implantation, while in the other case they were reduced
by one-half. If atrophy of the endometrium ensues, as in
the unsuccessfully treated Case 7, but bleeding nevertheless
persists, the amount of testosterone (less than 400 mg.)
may have been too small to depress the anterior lobe.
In fifty-five cases in which injections of testosterone propionate
have been given-reports on which will be
published later-an average of 700 mg. of testosterone propionate
had been necessary in cases of hyperfolliculinaemia
in order to obtain the desired results. It might
perhaps be suggested that this dosage, which might be
called "hormone atrophy dose" for the endometrium
(H.A.D.), should be designated as a basic value and only
a portion of it be given, depending on the case. It is
approximately twenty times the dose of follicular hormone
necessary to attain a normal proliferation of the
endometrium in cases of absent ovaries or of primary
amenorrhoea (35 mg. oestradiol benzoate). This might be
called the "hormone proliferation dose" for the endometrium
(H.P.D.) (1933, 1934). For antagonizing this
proliferation dose the atrophy dose of testosterone would
be necessary.
If pronounced hyperfolliculinaemia and hyperproliferation
exist this atrophy dose would have to be increased.
Even the largest doses of male hormone, such as were
injected in earlier attempts, do not act on the fibroids
themselves, which, according to our present-day concepts,
are considered to be the result of hyperfolliculinaemia.
In the case of one patient who had been treated with such
large doses by injection, and on whom I subsequently
performed a supravaginal amputation of the uterus, the
histological examination of the fibroid (performed by Dr.
Oliver) revealed no change.
In the five women with haemorrhages treatment was
successful in three, of only limited success in one-a
younger woman (Case 4) in whom after an accident the
tablets were expelled-and unsuccessful in one (Case 7),
in whom the amount of the implanted hormone was
too small. Improvement was obtained in the two women
with chronic mastitis. It is known, and has been established
particularly by French authors, that even small
doses when injected give good results in this conditiona
view also supported by workers in this country (Spence,
1939). But in this connexion it must be observed that
results are also to be obtained with follicular hormone and
other methods of treatment, such as diathermy. Treatment
with male hormone is based on the fact that excess
of follicular hormone produced in the body causes the
proliferative processes in the breast, and that this excess
cannot be antagonized for a long period by small doses
of male hormone, but only by really large ones.
Testosterone and Cancer
If it is assumed that excess of follicular hormone can
produce not only proliferative processes in the mammary
gland but perhaps even precancerous processes, treatment
with male hormone as an antagonist would be justified
in cases of cancer of the breast. Experimental investigations
with testosterone in mice with high incidence of
cancer of the breast are available (Lacassagne, 1937;
Flacks and Isser, 1938). Testosterone propionate acted in
a prophylactic manner. I have had under observation two
patients whose breasts were removed for cancer and who
suffered from recurrences at frequent intervals. The recurrences
had disappeared after irradiation when I saw
them. I treated them for menorrhagia with injections of
testosterone propionate, and up to date there has been no
further recurrence for two and a half years ; this suggests
that testosterone had an inhibiting effect (1939).
In my two cases of cancer (11 and 12) testosterone had
no effect on the growth itself.
General Effects of Testosterone Therapy
All patients who have been treated show throughout
the following general effects: (a) Enlargement of the
clitoris so long as the male hormone was acting. No
patient found this to be unpleasant. (b) Increased sexual
drive even in older women. The fact that this can be
found without a single exception, even when the male
hormone is given by injections in sufficient amounts, shows
that testosterone can be designated as an infallible aphrodisiac,
although of course only doses over 300 mg. have
effect. (c) Deepening of the voice without anatomic alteration
of the vocal cords. This disappears after three or
four months. (d) Temporary occurrence of lanugo on
the face, which also disappears again after some time.
As regards the psychic side of the patients treated in
this manner, they all acknowledge a great feeling of wellbeing,
more balanced moods, and clearer thinking; and
some profess also a greater determination. We might
therefore speak of a "chemistry of the emotions " in
order to express that the temperament is influenced by
the chemical substance so long as the hormone is active.
It would be interesting to go further into this side of
hormone therapy, and to study how the feelings might
be chemically controlled. Some of Freud's theses would
perhaps have to be modified. Such discussions, however,
would lead too far from the original theme.
Summary
1. Female and male hormone can be implanted in
tablet form in as large amounts as desired without injury.
2. Female hormone was implanted to allow a small
infantile uterus to develop and to make it ready for conception,
and this was done successfully.
3. Male hormone was implanted to control serious
menorrhagia caused by fibroids. Good results were obtained
in the case of women near the menopause.
4. Male hormone was unable to influence successfully
existing recurrences of carcinoma of the breast following
an operation or x-ray treatment. To what extent male
hormone can have a prophylactic action against such
recurrence is not yet determined.
5. The general effect of implants of male hormone on
women is discussed.
I am highly indebted to Dr. Macbeth of Organon Laboratories,
and Dr. Neuman of Schering Ltd. for supplying these
tablets.
