Circulating Inhibin A and Inhibin B in Normal Menstrual Cycle during Breeding Seasons of Japanese Monkeys
In order to clarify the endocrinological profiles of inhibins during normal menstrual cycles in Japanese monkeys, plasma concentrations of inhibin A and inhibin B were measured by enzymelinked immunosorbent assay. In addition, circulating gonadotropins and steroid hormones were measured. Blood samples were taken from four Japanese monkeys showing normal menstrual cycles. Plasma inhibin A remain...
متن کاملProduction of inhibin A not B in rams: changes in plasma inhibin A during testis growth, and expression of inhibin/activin subunit mRNA and protein in adult testis.
Previous studies have shown that changes in the plasma concentrations of immunoreactive inhibin measured by radioimmunoassay occur in parallel with growth and regression of the testes during a reproductive cycle in adult Soay rams induced by exposure to an artificial lighting regimen of alternating 16 week periods of long days and short days. With the development of new two-site ELISAs for shee...
متن کاملImmunolocalization of inhibin/activin subunit proteins during the breeding season in testes and scented glands of muskrats (Ondatra zibethicus).
The objective of this study was to investigate the cellular immunolocalization of inhibin a and inhibin/activin (β(A) and β(B)) subunits in the muskrat testes and scented glands during the breeding season. Inhibin α and inhibin/activin (β(A) and β(B)) subunits were expressed in Sertoli cells and Leydig cells of testes and glandular cells of scented glands, respectively. Also, positive signals o...

متن کاملResponse of serum inhibin B and pro-alphaC levels to gonadotrophic stimulation in normal men before and after steroidal contraceptive treatment.
BACKGROUND Testicular regulation of inhibin B may be influenced by the germ cell complement. METHODS We examined the effects of gonadotrophin stimulation on serum inhibin B and pro-alphaC in 25 normal men at (i) control (stimulation test 1), (ii) after spermatogenic suppression induced by testosterone plus progestin treatment (stimulation test 2), and (iii) during spermatogenic recovery induc...
