چکیده

UNLABELLED Conventional diagnostic procedures failed to provide a definitive diagnosis in a 15 year-old girl presenting with severe hirsutism, oligomenorrhea, and markedly elevated serum testosterone levels. To examine whether androgen overproduction was luteinizing hormone (LH) dependent and thus likely of ovarian origin we performed a new test to suppress LH secretion based on the use of Cetrorelix, a short-acting gonadotropin-releasing hormone antagonist. Subcutaneous administration of Cetrorelix 250 microg once daily for 5 days resulted in partial suppression of serum LH and testosterone. The same dose administered twice daily for 5 days almost completely suppressed serum LH and testosterone, thereby supporting a diagnosis of ovarian androgen excess. This observation was confirmed by a positive human chorionic gonadotropin stimulation test and an MRI showing bilateral polycystic ovaries. CONCLUSION The Cetrorelix suppression test appears to be a promising instrument to help solve the differential diagnosis of severe hyperandrogenism in adolescence.

Cetrorelix suppression test to assess the source of androgen overproduction in postmenopausal hirsutism.

UNLABELLED A 75-year-old woman presenting with recent onset hirsutism and severely elevated serum androgen levels was evaluated to assess the source of excessive androgen production. Commonly recommended hormonal stimulation and suppression tests, and the usually employed imaging techniques were non-diagnostic. In this report, we describe a new suppression test based on the use of the GnRH rece...

The Diagnosis of Polycystic Ovary Syndrome during Adolescence.

BACKGROUND/AIMS The diagnostic criteria for polycystic ovary syndrome (PCOS) in adolescence are controversial, primarily because the diagnostic pathological features used in adult women may be normal pubertal physiological events. Hence, international pediatric and adolescent specialty societies have defined criteria that have sufficient evidence to be used for the diagnosis of PCOS in adolesce...

Three different sets of diagnostic criteria have been established in order to define this disease in adult women, but there is controversy regarding the use of these criteria in adolescence. During puberty, the adult criteria...

Suppression of spermatogenesis to azoospermia by combined administration of GnRH antagonist and 19-nortestosterone cannot be maintained by this non-aromatizable androgen alone.

BACKGROUND For male hormonal contraception, combined administration of gonadotrophin-releasing hormone (GnRH) antagonists and androgens effectively suppresses spermatogenesis to azoospermia. In non-human primates this suppression can be maintained more easily by androgens alone. METHODS A clinical trial with six healthy volunteers was performed to test this approach in man. Loading doses of 1...
