HIV Counseling Prevention Strategy Women's Experiences
2009/9/17
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...
Demonstration of the role of prostate-specific antigen in semen liquefaction by two-dimensional electrophoresis
prostate-specific antigen semen liquefaction two-dimensional electrophoresis
2009/2/23
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...
Possible role of elongated spermatids in control of stage-dependent changes in the diameter of the lumen of the rat seminiferous tubule
elongated spermatids stage-dependent changes rat seminiferous tubule
2009/2/23
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...
Evidence for a role of cyclooxygenase（prostaglandin synthetase）and prostaglandins in the sperm acrosome reaction and fertilization
spermatozoa fertilization acrosome reaction cyclooxygenase prostaglandin inhibitor
2009/2/23
Three cyclooxygenase (prostaglandin synthetase) inhibitors, indomethacin, phenylbutazone, and oxyphenbutazone, decreased fertilization in vitro when mixed with capacitated mouse spermatozoa before a...
The role of endogenous opioid peptides in the control of androgen levels in the male nonhuman primate
morphine endorphin enkephalin naloxone
2009/2/20
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...
Role of the pineal in the alteration of hamster Sertoli cell responsiveness to FSH during testicular regression
pineal hamster Sertoli cells testicular regression short photoperiod optic enucleation
2009/2/20
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...
Do endocrines play an etiological role in diabetic and nondiabetic sexual dysfunctions?
endocrinology of sexual dysfunction diabetes sexual arousal nocturnal penile tumescence
2009/2/20
Sexually dysfunctional diabetic and nondiabetic males were compared with a group of normal controls using different endocrinological, psychophysiological, and psychological parameters. One hundred m...
Regulation of gonadotropin secretion in the male dog. Role of estradiol
gonadotropin secretion male dog
2009/2/19
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...
A study of phospholipase in albumin and its role in inducing the acrosome reaction of guinea pig spermatozoa in vitro
capacitation acrosome reaction spermatozoa
2009/2/19
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...
Evidence for a Role of Post-Ovulatory Cumulus Components in Supporting Fertilizing Ability of Hamster Spermatozoa
fertilization in vitro capacitation acrosome reaction egg-cumulus complex golden hamster
2009/2/19
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 ...
Role of Hyaluronidase in Fertilization: The Antifertility Activity of Myocrisin, a Nontoxic Hyaluronidase Inhibitor
myocrisin hyaluronidase inhibitor fertilization contraception
2009/2/18
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...
Evidence for the role of heterotrimeric guanine nucleotide-binding regulatory proteins in the regulation of the mouse sperm adenylyl cyclase by the egg's zona pellucida
Pertussis toxin acrosome reaction mastoparan cyclic
2009/2/18
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...
