The goal of the present investigation was to determine in the squirrel monkey the source and pattern of inhibin, a hormone known to effect reproductive steroid levels via pituitary and ovarian mechanisms. Since this seasonally polyestrous species is

The effects of corticosterone (B) and testosterone (T) on pituitary and serum bioactive and immunoreactive gonadotropins and on gonadotropin hormone subunit messenger RNA levels were compared in the absence of GnRH. Male rats were implanted with pell

Follistatin is an activin-binding glycoprotein that decreases FSH secretion in vitro and in vivo in rats. The mechanism by which follistatin acts is unclear, but it has been suggested that it may bind endogenous activin and neutralize its effects. In

Experimental objectives were to determine: 1) if the native glucocorticoid, corticosterone (B), can selectively increase pituitary FSH and FSH beta messenger RNA (mRNA) in the presence or absence of a GnRH signal; and 2) if B affects the biological a

In prepubertal rats, removal of one testis (hemicastration) results in increased FSH secretion and a compensatory hypertrophy of the remaining testis. To determine whether these two events are related, testis weight was measured after inhibin-rich po

A technique for sorting live LH- and FSH-secreting cells was developed. After enzymatic dispersion, a suspension of pituitary cells from male rats castrated 7 days earlier was incubated in potassium chloride (KCI 50 mmol/l) for 30 min and gonadotropi

The endocrine or local actions of inhibin-related peptides synthesized by the primate corpus luteum (CL) remain undefined. This in vivo study was designed to determine whether exogenous inhibin or activin modulates pituitary gonadotropin secretion an

In men, administration of exogenous testosterone (T) exerts direct negative feedback effects at the pituitary as well as at the hypothalamic level. This study was undertaken to determine whether T itself causes the inhibitory effects on the pituitary
