Serum FSH-suppressing activity of human recombinant inhibin A in male and female rats.
After a single i.v. injection of purified human recombinant inhibin A (hr-inhibin) or bovine follicular fluid (bFF) to 3-day castrated 35-day-old male rats, serum FSH concentrations fell (P less than 0.05) between 4 and 8 h, returning to control concentrations by 16-24 h. Administration of graded doses of hr-inhibin (0.625-10 micrograms/100 g body wt) and bFF (31.3-250 microliters/100 g body wt...
متن کاملComparison of serum FSH and Inhibin B levels between adult male dizygotic and monozygotic twins.
BACKGROUND FSH hypersecretion occurs in mothers of dizygotic (DZ) twins. Twinning is inherited via both sexes and transmitted through the female. FSH hypersecretion may thus occur in male DZ twins. METHODS We assayed FSH and its counter-regulatory hormone, Inhibin B, in 108 adult male DZ and 100 monozygotic (MZ) twins (as controls) and compared our results to published norms. RESULTS Inhibi...

15 صفحه اولEffect of short period vasectomy on FSH, LH, inhibin and testosterone secretions, and sperm motility in adult male rats.
The present study was undertaken to clarify changes in secretions of FSH, LH, inhibin and testosterone, and sperm motility after bilateral vasectomy in adult male rats. Bilateral vasectomy was created surgically (treated group) and intact rats were used as control (control group). On days 3, 5, 7, 14, 30, 60, and 90 after surgery, plasma concentrations of FSH, LH, inhibin, and testosterone were...
متن کاملFSHbeta gene mutation in a female with delayed puberty and hypogonadism: response to recombinant human FSH.
We report a woman with primary amenorrhoea and infertility associated with an isolated deficiency of pituitary FSH that does not respond to GnRH administration. Serum inhibin B was undetectable and antimullerian hormone (AMH) was within the normal range. Ultra sound examination revealed a small uterus and small ovaries with few small follicles. We identified an homozygous 1-bp (G) deletion at c...
