BACKGROUND Prior reports suggest a link between gonadotropin-releasing hormone (GnRH) and gastrointestinal function. The aim of the study was to prospectively investigate women subjected to in vitro fertilization (IVF) using the GnRH analog buserelin, taking into account gastrointestinal symptoms and antibody development against buserelin, GnRH, luteinizing hormone (LH), and their receptors. ...

One hundred anestrous mares (early February) were injected s.c. with implants containing 0, .9, 1.8, 3.6, or 5.4 mg of a GnRH analogue (goserelin acetate) in an attempt to induce ovarian cyclicity. Follicular activity and concentrations of progesterone and LH were determined every 3 d, or daily during estrus. In treated mares that ovulated, the interval to the second ovulation of the season was...

The aim of this study was to compare the clinical and hormonal effects of the combination of a long-acting gonadotrophin-releasing hormone analogue (GnRH-a) plus an oral contraceptive (OC) pill containing ethinyl-oestradiol (EE) and cyproterone acetate (CPA) versus the EE-CPA pill alone in patients with polycystic ovarian disease (PCOD) and related hyperandrogenisms, in order to evaluate whethe...
