[Follow-up checks of children born from induced pregnancy (author's transl)].

The following results were obtained by the authors from follow-up checks of 102 children, aged between 2.5 and eight years, who had been delivered from induced pregnancies. - Developmental abnormalities were recorded from seven cases, in the context of paediatric examinations. Minimal neurological deviations were exhibited by 14 children. Moderate retardation was established in psychological tests from something between 25 and 30 per cent of all cases. Positive responses to electroencephalography, however, without any clinical symptoms were observed in 20 per cent of the probands. Neurological symptoms and moderate retardation were recordable primarily from children who had originated from pathological pregnancies. The above findings are likely to support the recommendation to continue treatment of functional sterility by means of induced ovulation. Yet, treatment of that kind should be restricted to women unlikely to be afflicted with pathological pregnancy, which however, cannot be safely forecast in all cases.

Prostaglandin synthesis and metabolism in the human uterus and midtrimester fetal tissues.

Prostaglandin (PG) synthesis and metabolism was studied in human fetal kidney, lung, small intestine, heart, brain and liver (gestational ages: 10, 12, 14, 18 and 23 weeks) and pregnant uterus (4-40 weeks of pregnancy). PG synthesis was increased in the myometrium during pregnancy while the capacity of metabolism did not change. PG synthesis increased in lung and kidney (4-fold), brain (20-fold) and small intestine (2-fold) but not in heart or liver. Metabolic activity increased only in fetal kidney and lung.

Bromocryptine therapy in luteal insufficiency.

Fifteen cases of female infertility, probably connected with luteal insufficiency, are reported. This abnormality was found to be fairly common in hyperprolactinaemic and clomiphene-treated normoprolactinaemic women with galactorrhoea. Bromocryptine reduces the prolactin-level, prolongs the luteal phase and increases the secretion of progesterone. According to the observations thus far reported, some optimum prolactin concentration seems to be desirable for an adequate luteal function. In the case of luteal insufficiency, estimation of the prolactin and progesterone level in the luteal phase is advocated. The basal temperature curve the hyperthermic phase to be followed up before and after treatment allows.

Impaired spermiogenesis as a common finding among professional drivers.

The effect of long-term driving upon spermiogenesis was investigated in 2984 patients, including 281 professional drivers. The incidence of pathospermia was significantly increased among the 281 occupational drivers as compared to other professionals. The ratio of severe pathospermia was increased in proportion to the number of years of driving. The deterioration of spermiogenesis was mild among car drivers, but was severe in agricultural-industrial hard machinery and farm equipment drivers. There was a higher incidence of impaired fertility in drivers as compared to other professionals. The possible factors influencing these results are discussed.

Bradykininase and protease inhibitors in seminal plasma of fertile and infertile men.

The level of protease acrosin in the seminal plasma of oligozoospermic men was significantly higher than that of normozoospermic men. The amount of bradykininase in the seminal plasma was very high in both normozoospermic and oligozoospermic patients. When the acrosin and kininase content was referred to one million spermatozoa, seminal plasma kininase was significantly enhanced in oligozoospermic men, while the acrosin activity was similar in normozoospermic fertile men and infertile men. Human seminal plasma inhibitor I (HUSI I) increased along with sperm count. Human seminal plasma inhibitor II (HUSI II) showed no change. The motility of spermatozoa was depressed in oligozoospermic patients.

[Hormonal situation on parturition, early puerperium, and lactation (author's transl)].

Variations of the 17-beta oestradiol, progesterone, and prolactin levels in the serum were studied in the context of ten spontaneous parturitions. All cases were investigated within the first five puerperal days, but in five cases additional checks were undertaken over the first four weeks of the puerperium. Milk secretion was measured, as well. The oestradiol and progesterone titres were found to remain below the level common toward the end of pregnancy. They dropped rapidly after parturition and remained low throughout the puerperium. Prolactin underwent slight variation on parturition, but it actually stayed at the high level measurable at full term. Parturition was followed by brief temporary rise and, again, by decline, but values remained above those of non-pregnant women throughout puerperium. Milk production increased gradually over the first five days and remained similarly high throughout several weeks, accompanied by accordingly high prolactin levels. No absolute correlation was found to exist between the extent of lactation and the prolactin level. The presence of a relationship between oestradiol and progesterone levels, on the one hand, and lactation, on the other, cannot be assumed with probability.

[Clinical importance of antiprolactinaemic treatment of functional infertility (author's transl)].

Reported in this paper is the effectiveness of antiprolactinaemic treatment of 40 infertile women. All case histories revealed previous unsuccessful attempts to induce ovulation. Antiprolactinaemic treatment was in all cases preced by RIA determination of prolactin and gonadotrophin. Prolactin levels were found to be somewhat increase in 19 cases, while 21 women were normal. The gonadotrophin plasma levels usually were closer to the lower limits of normal values. The presence of hypophyseal adenoma had been ruled out beforehand. Long-time treatment was based on the administration of 5 mg Parlodel/die. The effect was excellent in all cases of hyperprolactinaemia, but response was recorded, as well, from a group of patients with normal prolactin levels. Galactorrhoea ceased to exist in all cases. Clomiphen was applied again to induce ovulation in those patients who had not responded at all or developed only bleeding without ovulation. That treatment proved to be effective in several cases.
