Objective: In the current study the efficacy of maternal hyperoxygenation on growth-retarded fetuses was evaluated., Study Design: Thirty-six pregnant women with intrauterine growth retardation were studied. The patients were divided in oxygen-treated (n = 17) and untreated (n = 19) groups. Doppler analysis of the fetal circulation was performed on the arrival to the hospital, after 12 hours, and thereafter on alternate days until delivery. Fetal blood was sampled by cordocentesis for immediate blood gas analysis at entrance to the study and the day of delivery., Results: Significant improvement in Doppler flow patterns in treated patients were found when compared with untreated women. The Doppler variations were associated with complementary modifications in fetal blood gas. These differences resulted in a significant modification in perinatal mortality with an incidence of 29% and 68% (p less than 0.01) in treated and untreated groups, respectively., Conclusion: Our data suggest a benefit of maternal hyperoxygenation in the treatment of fetal growth retardation.

Retrograde ejaculation is an uncommon form of male infertility. It may occur in diabetics from neuropathy involving the sympathetic fibers innervating the bladder neck. Treatment of infertility in these cases is with artificial homologous insemination. Several techniques for semen recovery from the bladder have been proposed. This paper describes a case of twin pregnancy following direct intraperitoneal insemination (DIPI) of semen retrieved from a diabetic man with retrograde ejaculation. Retrieval of semen was performed in this case by spontaneous voiding of urine after the introduction of a suitable medium into the bladder and before ejaculation. The quality of the semen was examined after spontaneous urination before DIPI. The poor quality of the spermatozoa induced us to introduce into the bladder a suitable medium before ejaculation and sperm recovery.

The follicular fluid (FF) content of androgens, estrogens and epidermal growth factor (EGF) has been evaluated in a group of patients with policystic ovary disease (PCO) and in one of normally-ovulating infertile women (NOW) in an IVF/ET program. The in vitro response to follicle-stimulating hormone (FSH) has been also evaluated in granulosa luteal cells from the same patients. PCO patients showed significantly higher FF androstenedione (delta 4) and testosterone (T) and similar FF estrone (E1) and 17 beta-estradiol (E2) levels compared to controls. In vitro production of E1 and E2 by granulosa luteal cells from PCO patients and from controls were overlapping and their response to FSH was similar. These data indicate a normal intrinsic potential aromatase activity in ovaries from PCO patients stimulated with gonadotropins and suggest that PCOs do not derive from inherent ovarian aromatase deficiency. Increased FF androgen content following gonadotropin stimulation may result from theca cell hyperactivity and androgen accumulation in the follicular antrum of rescued hyperandrogenic follicles as well as from inhibitory factors that may inhibit aromatase activation in vivo, partially counteracting the effect of gonadotropins. FF EGF levels were significantly higher in the group of PCO patients compared to those of NOW. EGF may play a role in blunting the in vivo response of granulosa cells to gonadotropins.

A patient with a history of two spontaneous abortions, at the 16th and 20th week, respectively, and one intra-uterine fetal death at the 26th week of gestation was investigated. The sole abnormal condition that could be evidenced was a submucosal leiomyoma of 56 mm in diameter in the uterine fundus. Administration of gonadotropin/releasing hormone analog (GnRHa) for 10 months resulted in complete disappearance of myoma. Direct intraperitoneal insemination following induction of ovulation resulted in pregnancy. In a patient harboring uterine leiomyomas, adversely affecting conception and pregnancy outcome, GnRHa treatment may be an initial approach allowing to avoid pelvic surgery. As the beneficial effect of GnRHa might be temporary, assisted reproduction procedures might anticipate conception.
