CONTEXT: It is unclear why women decide to undergo testing for HIV, and how positive and negative test results impact their sexual behavior. METHODS: A sample of 360 family planning clinic clients...
Two-dimensional protein profiles of human semen, prostatic fluid, and seminal vesicle fluid were compared to demonstrate changes in the protein composition of human semen before and after liquefac...
Adult male rats were treated with a single dose of 650 mg/kg methoxy acetic acid to deplete the seminiferous tubules specifically of pachytene and later spermatocytes. The effect of this treatment a...
Three cyclooxygenase (prostaglandin synthetase) inhibitors, indomethacin, phenylbutazone, and oxyphenbutazone, decreased fertilization in vitro when mixed with capacitated mouse spermatozoa before a...
Plasma androgen levels studied following the injection of the opioid agonists morphine sulfate (0.5-1.0 mg/kg), beta-endorphin (10-20 mg/kg), and [D-Ala2, D-Leu5]-enkephalin (DADLE; 5-20 microgram...
Testicular regression was induced in adult hamsters by optic enucleation, short photoperiod, or melatonin injections. The melatonin injected group, while undergoing testicular regression, showed a q...
Sexually dysfunctional diabetic and nondiabetic males were compared with a group of normal controls using different endocrinological, psychophysiological, and psychological parameters. One hundred m...
Steroid regulation of pituitary LH and FSH secretion in the male may be mediated via the direct action of testosterone, or via the conversion of testosterone to either dihydrotestosterone (DHT) or e...
Phospholipase activity associated with guinea pig spermatozoa during capacitation and the acrosome reaction (AR) was determined by measuring the production of [14C] glycerylphosphorylcholine (GPC) f...
A completely chemically defined culture medium was used to investigate the role of egg-cumulus complex (ECC) components in supporting sperm fertilizing ability. Defined sperm motility-stimulating ...
Myocrisin, a hyaluronidase inhibitor of low molecular weight, was tested for antifertility activity. In addition, the effect of myocrisin on penetration of the follicle cell layer by spermatozoa w...
Sperm acrosomal exocytosis is the result of a complex set of signal transduction pathways activated physiologically by the egg's extracellular matrix, the zona pellucida. In the mouse, the zona pe...
Human and monkey ejaculated sperm contain protein phosphatase-1 (PP1), PP1 inhibitor 2 (12), and glycogen synthase kinase-3 (GSK-3). Inhibition of ejaculated human sperm protein phosphatase (PP) a...
Human serum albumin (HSA) is being considered as an alternate media for sperm enrichment in assisted reproductive technology (ART) because of recent concern with the use of Percoll. In this study,...
Erection is mediated by relaxation of the smooth muscle elements within the sinusoids of the corpus cavernosum. Although cavernosal relaxation can be mediated by a variety of mechanisms including pu...
