Luteinizing hormone releasing hormone agonist, [(imBzl)-DHis6,Pro9,NEt]-LHRH (LHRH-A), caused a two to threefold increase in in vitro testosterone (T) secretion by rat Leydig cells. This LHRH-A-indu...
To determine if ram principal cells can synthesize or metabolize testosterone, or metabolize other steroids present in rete testis fluid, principal cells from the initial segment, central caput, and...
The effects of short-term hypoprolactinemia on the pituitary-gonadal axis were evaluated in a group of patients with untreated prostatic carcinoma. Each patient was studied prior to and during 7-day...
To investigate mechanisms responsible for gonadotropin-releasing hormone (GnRH)-stimulated Leydig cell steroidogenesis, the effects of GnRH agonist [des-Gly10, (D-Ala6) GnRH] on phospholipid turnove...
The present study was designed to elucidate mechanisms responsible for gonadotropin-releasing hormone (GnRH)-stimulated testosterone formation. Purified Leydig cells from adult Sprague-Dawley rats...
The effects of chronic treatment with hCG (100 I.U.s.c. every second day) on testicular morphology, LH receptor levels and concentration of steroid intermediates of the 4 and 5 biosynthetic pathwa...
Following the recent observation that chronic treatment with [D-Ala6, des-Gly-NH210]LHRH ethylamide, a potent LHRH agonist, leads to an almost complete degeneration of seminiferous tubules in the ra...
Previous reports have demonstrated that corticotropin-releasing hormone (CRH) treatment of primary cultures of mouse Leydig cells and MA-10 mouse Leydig tumor cells results in a dose-dependent sti...
We studied the testicular function and some androgen-mediated events in 22 males (16-30 years of age) with male pattern baldness that was treated with finasteride (10 mg once daily) for 2 years. Pat...
A stallion testicular cell incubation system was developed and used to investigate the regulation of steroidogenesis in stallion testes. Cells isolated from testes of 2- to 4-year-old stallions (n = 6...
We have investigated the effect of acute immobilization (3 hours) stress on testicular steroidogenesis in the adult rat. Immobilization did not alter plasma luteizing hormone (LH) levels, but plas...
Finasteride, a 5 alpha-reductase inhibitor, does not bind to the androgen receptor and has no other known hormonal activity. To determine what effect, if any, it has on adrenal steroidogenesis, 10...
Treatment of cultured testicular cells from adult rats with 5 alpha-dihydrotestosterone (DHT; 10(-6) M) or the synthetic androgen methyltrienolone (R1881; 10(-6) M) inhibited Leydig cell 3 beta-hy...
In seeking an animal model of age-associated changes in the male reproductive tract, we examined the effects of age on the health and testicular steroidogenic activity of the Brown Norway rat, with ...
The phenotypic actions of the oligotriche gene mutation on testicular function have not been elucidated, although it is known that male mice homozygous for the mutation are infertile. In the present...
