A selective increase in circulating inhibin and inhibin pro-αC at the time of ovulation in the mare.
The relationship between a selective increase in circulating immunoreactive (ir)-inhibin and the time of ovulation was investigated in mares. Concentrations of plasma ir-inhibin were measured every 4 h during the periovulatory period. Inhibin pro-αC, a precursor protein of the inhibin α-subunit, was also measured. The changes in ir-inhibin and inhibin pro-αC in circulation were parallel. Concen...
متن کاملBeta-endorphin in serum and seminal plasma in infertile men.
AIM To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD)...
متن کاملA Correlation of Serum Inhibin with Sperm Count and Sperm Motility in Fertile and Infertile Males
Inhibin is produced by Sertoli cells of the testis, provides negative feedback on FSH secretion, and may prove to be an important marker for the functioning of seminiferous tubules. The purpose of this study was to examine the relationship between the spermatogenic function of the tests of subfertile men and the plasma concentrations of inhibin. The study was carried out on twenty infertile (or...
متن کاملSerum inhibin levels in normal men and men with idiopathic infertility.
In vitro studies have shown that the Sertoli cell is the primary source of inhibin in the male. To assess the regulation of inhibin production we measured serum inhibin, FSH, LH and testosterone in 21 normal men and 104 men with various testicular disorders resulting in infertility. The infertile men were subdivided into groups on the basis of their mean sperm count, FSH and LH levels. The mean...
متن کاملIdentity suffering in infertile men
The suffering caused by infertility in a man can have multiple aspects. It can display a narcissistic dimension, an objectal dimension (object-libido) turned toward others or/and an identity dimension. Two clinical case reports were used here to (i) illustrate all these aspects of infertility suffering, (ii) to evidence the difficulty for infertile men to speak about their infertility and (iii)...
