Aim: To investigate hCG levels in follicular fluid and serum after intramuscular (IM) or subcutaneous (SC) administration of purified hCG, and their association with oocyte maturation and body mass in...
Objective: Our purpose was to determine whether unexplained elevations in maternal serum human chorionic gonadotropin (hCG)in the second trimester is associated with an increased risk of preeclampsia....
While GnRH is known to stimulate release of pituitary gonadotropins, its acute effects on the kinetics of secretion of the various hormones and subunits are not well characterized. Pulse-chase exp...
The testosterone dose-dependency of several mating and nonmating behaviors was examined in the male rat, chemically castrated with a GnRH antagonist analog. Graded doses of testosterone enanthate ...
Increasing interest in events regulating gonadotropin synthesis and secretion led to the reexamination, by radioimmunoassay (RIA), of the pituitary content of luteinizing hormone (LH) and follicle s...
The functional characteristics of the hypothalamic-pituitary-testicular axis were examined quantitatively in 10 chronic alcoholic men without hepatic dysfunction or clinical nutritional deficiencies...
Alterations in testicular morphology were studied in boars actively immunized against gonadotropin hormone releasing hormone (GnRH). Ten boars were divided equally into two experimental groups (five...
Endogenous testosterone (T), LH and FSH receptors, and in vitro production of cyclic adenosine-3':5'-monophosphate (cAMP), T and some of its steroid precursors were measured in testicular tissue obt...
Eight patients with advanced prostatic carcinoma (ages 59 to 78 years) were treated with a potent gonadotropin-releasing hormone (GnRH) agonist analog (buserelin, Hoechst; 600 micrograms intranasall...
Hormone levels, physiologic parameters, electroencephalographic (EEG) activity, and changes in subjective feelings recorded using a nonverbal instrumental device were assessed following the double-b...
Testosterone is aromatized to estradiol in both peripheral tissues and the central nervous system. Various authors have suggested that this conversion in the male may be prerequisite for the regulat...
Hypophysectomized male rats were administered LH or LH + FSH for 14 days and subjected to in vivo micropuncture collection of reproductive tract fluids to determine if FSH alters the compartmentaliz...
Involvement of endogenous estrogen in the regulation of gonadotropin and testosterone secretion was investigated in adult rams. Groups of four rams were either passively immunized against estradio...
The precise hormonal milieu required for quantitatively normal spermatogenesis in man is unclear. The authors previously have shown that both supraphysiologic dosages of human chorionic gonadotropin...
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...
