[Results of treating cryptorchism with HCG in boys previously qualified for surgical treatment].

Hundred one boys, aged between 1.5 and 13 years, previously classified for surgery for uni- or bilateral cryptorchidism were examined. In 78 patients (77.

[Development of biological value of sperm in delayed puberty].

Changes in the biological value of sperm depending on the time of the first ejaculation are presented. A control group included 194 boys with normal puberty in whom a biologic value of sperm was evaluated in dependence of the first ejaculation. In all time points a biological value of sperm was significantly worse in the delayed puberty than that in the control group.

[Histological structure of the testes in andropause].

A structure of the convoluted tubuli, spermatogenesis and number of Leydig's cells in the andropause have been analysed in dependence on the degree of symptoms intensity. A control group included otherwise healthy men with ++post-inflammatory azoospermia. A percentage of the convoluted tubuli with normal tissue (p < .

Fructosamine in human and bovine semen.

We detected the presence of fructosamine in human and bovine semen. In seminal plasma of healthy normozoospermic men (N = 17) fructosamine was found in 53% of the cases (fru+). In fru+ semen samples the concentration of fructosamine was (mean +/- S.

Male infertility and its treatment: a review of over 4700 patients treated for male related infertility.

Changes in semen parameters are presented for 4708 patients treated for infertility. The largest group comprised patients with oligoasthenozoospermia of various grades (57.7%).

[Gonadal intraparenchymatous functional reserve in andropause].

Blood plasma testosterone (T), estradiol (E2) levels and gonadal reserve in 43 patients aged between 50 and 66 years with andropause symptoms have been determined. The patients were divided into 3 subgroups depending on the severity of the symptoms. No significant difference was noted in T level of these patients compared to the range in younger males as well as a control group of corresponding age but with no andropausal symptoms.

[Clinical andropause].

A group of 43 male patients aged between 50 and 67 years with the symptoms of andropause in presented. The patients were divided into three groups depending on the degree of the symptoms. Such a classification may facilitate a choice of therapeutical methods.

Testosterone, FSH and LH in human spermatic and cubital venous plasma in varicocele patients.

The plasma level of testosterone, FSH and LH were determined simultaneously in spermatic and cubital veins in 12 patients with varicocele. The testosterone levels in spermatic veins were 13.4 +/- 5.

Heterotopic adrenal tissue.

In a group of 102 adult patients operated upon for cryptorchism heterotopic adrenal tissue was found in two cases. In one case it was present in the inguinal canal and in another case it was situated at the border between the testicle and rete testis.

Semen characteristics in pubertal boys. IV. Semen quality and hormone profile.

The biological quality of semen was contrasted with levels of FSH, LH, and testosterone in plasma. The level of FSH rises significantly from azoospermia/cryptozoospermia (3.87 +/- 1.

Semen characteristics in pubertal boys. III. Semen quality and somatosexual development.

The biological quality of semen in 134 pubertal boys was contrasted with somatosexual development. The absence or sparcity of pubic and axillary hair, the absence of facial hair, and infantile-type penile growth are prominent characteristics in azoospermic and cryptozoospermic boys. Sparse or meager pubic hair, absence or sparcity of axillary and facial hair, and puerile penile type are characteristics in oligozoospermia.

Semen characteristics in pubertal boys. II. Semen quality in relation to bone age.

Semen specimens from 134 pubertal boys were examined and compared to bone age. Normal figures for semen volume, liquefaction, sperm concentration, and morphology were observed between 15 0/12 and 16 0/12 years of bone age. The number of normally motile spermatozoa became standard at 17 0/12 years of bone age.

Semen characteristics in pubertal boys. I. Semen quality after first ejaculation.

Semen specimens from 134 pubertal boys were examined, and some 274 assays were made. An analysis of the biological quality of semen in relation to the period of time after first ejaculation brings high values of statistical dependence of the volume of semen, its liquefaction, spermatozoal concentration, percentage of morphologically normal forms of spermatozoa, and normal spermatozoal motility on the period of time after first ejaculation. Normal figures for semen volume, semen liquefaction, spermatozoal concentration, and morphology are observed 12-14 months after first ejaculation.

Testosterone, FSH and LH in human spermatic and cubital venous plasma in post-inflammatory azoospermia.

The testosterone, FSH and LH plasma levels were determined simultaneously in spermatic and cubital veins in 15 patients with post-inflammatory azoospermia. The testosterone levels in spermatic vein was 13,1 +/- 2,9 times higher than in cubital vein. FSH spermatic plasma level was slightly higher than in cubital vein, whereas LH spermatic plasma level did not differ from that found in the cubital vein.

X-linked adult form of spinal muscular atrophy.

Neurological and endocrinological studies were carried out in 8 of 12 male patients with X-linked spinal muscular atrophy. In six investigated cases, gynaecomastia was discovered. First muscle symptoms started between 21 and 44 years of age, at which time the patients observed disturbances in their sexual life.

The effect of alkylating agents on the reproductive and hormonal testicular function in patients with rheumatoid arthritis.

An evaluation of testicular function was undertaken in 11 boys and young men aged 14-26 years suffering from rheumatoid arthritis complicated by amyloidosis and treated with cyclophosphamide and chlorambucil. 7 cases were studied during life and 4 at autopsy. Semen analysis showed azoospermia in 4 cases; in one, cryptozoospermia; in one, oligoasthenotheratozoospermia; and in one, asthenoteratozoospermia.

Investigation and results of treatment in male sterility.

The authors present the results of treatment in 6548 cases of male sterility. According to their findings 598 (9.1%) men were ineligible for treatment.

Varicocelectomy in patients with azoospermia.

The results of surgical treatment of 33 men with azoospermia and varicocele are presented. Microscopic examination of a testicular biospy revealed the Sertoli-cells-only syndrome in nine subjects while degenerative changes in the seminiferous tubules of one or both testes were present in another six persons. In 15 cases decreased spermatogenesis was noted in the testis on the side ipsilateral to the varicocele.
