Inverse correlation between baseline inhibin B and FSH after stimulation with GnRH: a study of serum levels of inhibin A and B, pro alpha-C and activ…
2000
OBJECTIVE: Interest has focused recently on the influences of the polypeptide factors inhibin and activin on the selective regulation of the pituitary secretion of gonadotropins. DESIGN: Measurement of the concentrations of inhibin-related proteins in relation to the changes in pituitary gonadotropin (FSH, LH) parameters, after GnRH stimulation with a bolus injection of 100 microg gonadorelin, in 19 women with ovulatory disturbances. METHODS: Serum levels of inhibin A and B, activin A, and pro alpha-C were measured using sensitive ELISA kits. RESULTS: Within 60 min after GnRH stimulation, FSH values doubled from 5 to 10 mU/ml (P < 0.001). LH increased 12-fold from 2 to 24 mU/ml (P < 0…
Risk Weighing in Twin Pregnancy
2010
Multiple pregnancies are more often associated with complications than singleton pregnancies. In our retrospective study of 613 twin pregnancies the most important risk factors in twin pregnancies were premature labour before the 37th week of gestation and the premature rupture of the membrane. The increase of perinatal mortality and morbidity for twins might be primary the result of premature delivery.
Concentrations of ovarian proteohormones as biological markers for the outcome of assisted reproductive technology
2002
Objective: To assess whether the ovarian proteohormones inhibin A and B, pro-alpha-C and activin A could act as direct biological markers of a poorer or better response to ovulation induction or clinical conception through assisted reproductive technology (ART). Methods: Seventy-seven women who underwent ART were included in the study and were divided into two groups: (i) 46 women with sonographically documented follicular maturation; and (ii) 36 women who demonstrated inadequate follicle development. Blood samples were analyzed for inhibin A, inhibin B, pro-alpha-C, activin A and estradiol (E2) at day 3 of stimulation with recombinant follicle-stimulating hormone (rFSH) after pituitary dow…

To investigate the influence of human recombinant follicle-stimulating hormone (FSH) on circulating serum concentrations of the ovarian proteohormones inhibin A, inhibin B, pro alpha-C, and activin A and serum levels of estradiol after down-regulation with GnRH analogue.Serum concentrations of ovarian proteohormones and estradiol.Academic clinical practice.30 women who underwent assisted reproductive techniques.Blood samples were analyzed for inhibin A, inhibin B, pro alpha-C, activin A, and estradiol during IVF treatment at points coinciding with pituitary down-regulation, stimulation with recombinant FSH, ovulatory triggering, and the luteal phase of the cycle.Activin A levels did not cha…
