Oligospermia due to partial maturation arrest responds to low dose estrogen-testosterone combination therapy resulting in live-birth: a case report. (1/7)

A man having severe oligospermia, due to partial maturation arrest at spermatid stage, was given low dose estrogen-testosterone combination therapy for three months. His sperm count increased enormously, following which his wife conceived and delivered a healthy baby at term.  (+info)

Inhibin production by bovine ovarian tissues in vitro and its regulation by androgens. (5/7)

No detectable amounts of inhibin were produced by cultured ovarian stroma or luteal tissue. Follicular tissue produced inhibin in vitro and removal of the granulosa cells from the follicle wall caused inhibin production to fall by 80%. Granulosa cells alone had the greatest ability of any ovarian cell type to produce inhibin in vitro, and are probably the major site of follicular inhibin production. Cyproterone acetate at concentrations of 35 and 350 microM inhibited basal and testosterone (3.5 microM)-stimulated inhibin production by cultured intact follicle wall and granulosa cells. In addition, each concentration of cyproterone acetate inhibited progesterone but not oestradiol-17 beta production by the follicle wall and granulosa cell cultures. The synthetic, non-aromatizable androgens, methylestrenolone and mesterolone, at concentrations of 5 and 25 microM, mimicked the effect of testosterone and stimulated granulosa cell inhibin production, methylestrenolone being the more potent. These findings provide further evidence that androgens regulate follicular inhibin and progesterone production and that these may be receptor-mediated processes, and suggest that inhibin production may be a general property of androgenic compounds. Preliminary examination of the physicochemical characteristics of inhibin indicated that the inhibin activity of bovine granulosa cell culture medium was (a) retained by an Amicon XM100A filter with a nominal molecular weight cut-off point of 100 000; and (b) destroyed by heating to 80 degrees C for 30 min.  (+info)

Mesterolone: thrombosis during treatment, and a study of its prothrombotic effects. (6/7)

1. We describe a patient who developed deep vein thrombosis after commencing treatment with the synthetic androgen, mesterolone (Pro-Viron). 2. To investigate the potential thrombogenic action of this drug, a 21 day course of mesterolone (100 mg/day) was given to nine healthy male volunteers. 3. No significant change after treatment occurred in any of the blood tests performed (clotting times, Factor VIII coagulant activity, Factor VIII related antigen, antithrombin III activity, fibrinogen, fibrinogen-fibrin degradation products, plasminogen, euglobulin lysis time, urokinase sensitivity, platelet count, haematocrit, whole blood viscosity and plasma viscosity). 4. We conclude that in a conventional dose taken for 3 weeks mesterolone does not produce a consistent measurable prothrombotic state, nor does it enhance fibrinolysis.  (+info)
