Background: We recently demonstrated the effect of gonadotropin-releasing hormone agonist (GnRHa) on tissue inflammation, angiogenesis and apoptosis in endometriosis, adenomyosis and uterine myoma. Here, we investigated expression of GnRH receptors (GnRHR) and effect of GnRHa on the proliferation of cells derived from endometria and pathologic lesions of women with these reproductive diseases. ...

A dot-blot immunoassay for the detection of vitellogenin (Vtg) in plasma of adult grey mullet (Mugil cephalus) was developed. The assay identified the sex of the tested fish prior to detectable gonadal development, enabling the establishment of broodstock at the desired ratio of 7:4 females to males. This broodstock was maintained under natural photoperiod, and used to study the relative effect...

IMPORTANCE Androgen-deprivation therapy (ADT) through surgical castration is equally effective as medical castration in controlling prostate cancer (PCa). However, the adverse effect profiles of both ADT groups have never been compared. OBJECTIVE To provide a comparative effectiveness analysis of the adverse effects of gonadotropin-releasing hormone agonists (GnRHa) vs bilateral orchiectomy i...

We report the results of administration of danazol after suspension of gonadotrophin-releasing hormone analogue (GnRHa) therapy for uterine myomas. A total of 21 women with uterine myomas was treated with 100 mg danazol for 6 months after GnRHa therapy. Uterine volume and endocrine status were monitored monthly by ultrasound and assay of plasma gonadotrophins, oestradiol and progesterone. The r...

Purpose: to evaluate the effect of previous ovarian surgery for endometriosis on the ovarian response in assisted reproduction treatment cycles and its pregnancy outcome. Methods: a total of 61 women, with primary infertility and previous ovarian surgery for endometriosis, submitted to 74 in vitro fertilization/intracytoplasmic spermatozoid injection (IVF/ICSI) cycles, were studied (study group...

BACKGROUND We recently demonstrated the effect of gonadotrophin-releasing hormone agonist (GnRHa) on tissue inflammation, angiogenesis and apoptosis in endometriosis, adenomyosis and uterine myoma. Here, we investigated expression of GnRH receptors (GnRHRs) and effect of GnRHa on the proliferation of cells derived from endometria and pathological lesions of women with these reproductive disease...

American shad is an anadromous fish that displays asynchronous ovarian development. In an effort to enhance our understanding of the reproductive cycle of this primitive Teleostei species, and provide better management tools for the Chesapeake fishery, we have conducted studies of its gonadal and hormonal cycles. We developed various assays to measure reproductive endocrine factors including: 1...

Central precocious puberty (CPP) is a diagnosis that pediatric endocrinologists worldwide increasingly make in girls of age 6-8 years and is mostly idiopathic. Part of the reason for increasing referral and diagnosis is the perception among the doctors as well as the patients that treatment of CPP with long-acting gonadotropin-releasing hormon analogues (GnRHa) promote height of the child. Alth...

BACKGROUND Information is limited regarding the multifunctional role of GnRH agonist (GnRHa) therapy in reproductive diseases. We investigated the pattern of changes in inflammatory reaction, micro-vessel density and apoptosis in the tissues collected from women with endometriosis, adenomyosis and uterine myoma who were treated with or without GnRHa therapy. METHODS Biopsy specimens were coll...
