[Methods of evaluating labor progress in contemporary obstetrics].

Assessment of progress in labor is one of the foremost problems in obstetrics. Obstructed labor increases danger to maternal and fetal life and health, and may be caused by birth canal pathologies, as well as inefficient uterine contractions or failure of cervical dilation. Such obstructions require the use of vacuum extraction, forceps, or a Caesarean section.

[Role of inflammatory cytokines in male infertility].

Male infertility is a serious diagnostic problem and in many cases the exact cause of failure to reproduce remains unknown. New diagnostic methods are being evaluated in search of more precise diagnosis and possibility of casual treatment. Measuring the level of cytokines, both in seminal plasma and serum, does not only expand the diagnostic options, but also, through the growing knowledge of immune processes, can give rise to new therapeutic methods of improving the quality of semen and increasing the chance to reproduce.

Clinical, hormonal and sonographic features of the identical twins with Klinefelter syndrome--a case report.

A rare case of Klinefelter syndrome in identical twins is reported. Hormonal levels before and after hCG administration and testicular artery Doppler flow measurements are presented.

Immunoexpression of androgen receptors and aromatase in testes of patient with Klinefelter's syndrome.

Klinefelter's syndrome (47, XXY) is the most common chromosome aneuploidy in men and is usually characterized by underdeveloped testes and sterility. The aim of the present study was to detect cellular distribution of androgen receptors (AR) and aromatase in testes of patient with KS. The tissue sections were processed for morphological and immunohistochemical staining.

The naloxone test in Klinefelter syndrome.

Unlabelled: AIM TO THE STUDY: The investigation of the influence of anti-opioid drug on hypophyseal and gonadal hormones secretion in case of Klinefelter syndrome.

Material And Methods: The naloxone test (0,4 mg iv) was performed in 14 patients with Klinefelter syndrome aged from 19 to 32 and in 12 age matched control subjects with azoospermia and normal spermatogenesis in testicular histology. The plasma levels of FSH, LH, prolactin, testosterone and estradiol were established before and after 30, 60, 60 and 120 minutes respectively, following the drug administration.

[Protocol of GNRH antagonist in poor responders in IVF-ET cycles].

Introduction: Response to stimulation is one of the factors that affect the results of infertility treatment in IVF-ET cycles. Poor responders as well as the occurrence of ovulation prior to the oocyte retrieval is a main reason of nearly 30% of cancellations of the treatment cycles. In poor responders high doses of gonadotrophins are sometimes required.
