Mating stimulation, particularly vaginal-cervical stimulation, causes estrous abbreviation in female rats. In most previous studies, female rats were repeatedly tested for sexual behavior until estrous termination occurred. Thus, it was not clear whether sensory stimulation (e.g., flank stimulation, olfactory cues) received during the repeated testing procedure contributed to estrous abbreviati...

OBJECTIVE To determine the role of adrenal androgenic hormone precursors in female sexual function. DESIGN A review of current literature on sexual function and the androgen precursor hormone dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS). RESULT(S) The C(19) steroid DHEA is both an ovarian and adrenal androgen precursor hormone, whereas DHEAS is only synthesized i...

BACKGROUND Reproductive endocrine disorders and sexual dysfunction are common among men with epilepsy. We investigated sexual hormone serum levels among men with newly diagnosed epilepsy, before starting any antiepileptic drug (AED), and then after starting carbamazepine (CBZ), to determine the role and effects of epilepsy versus CBZ in creating reproductive endocrine disorders. METHODS In th...

To reveal the reproductive biology in male bottlenose dolphins (Tursiops truncatus), circulating gonadotropins (follicle stimulating hormone [FSH] and luteinizing hormone [LH]) and testicular hormones (testosterone and inhibin) were monitored for 8-12 years in 2 captive bottlenose dolphins (Mars and Regulus). During the study period, Mars was undergoing sexual maturation, whereas Regulus was al...

Background: There is a great concern for the possible adverse effects of cell phones and noise waves and it looks these wave effects on the individuals’ health. Thus, the present study was conducted to examine the effect of cell phone waves, severity noise, and simultaneous effect of cell phone waves and severity noise on sperm motility and sexual hormones in adult male rats. Materials and Meth...

Juvenile hormone levels and adult diet have important effects on the attractiveness and competitiveness of male Anastrepha suspensa (Loew) (Caribbean fruit fly). Because the success of the sterile insect technique requires the release of males that can compete in the wild, these effects are of crucial importance. Laboratory and field cage experiments were conducted to compare male sexual perfor...

Physical and psychological stressors suppress hypothalamic-pituitary-gonadal axis activity and sexual behavior and consequently induce reproductive dysfunction. Recently, it has been shown that gonadotropin-inhibitory hormone (GnIH), also called RFamide-related peptide 3 (RFRP) in mammals, which is a potent inhibitory regulator of gonadotropin-releasing hormone (GnRH) and gonadotropin, is invol...

Testosterone, LH, FSH, PRL, and sex hormone binding globulin (SHBG) were measured in 72 male epileptic patients on chronic anticonvulsant drug regimes. Sexual activity was estimated and plasma anticonvulsants measured. Total testosterone (TT), LH, FSH, PRL, and SHBG were increased; free testosterone (FT) was decreased. Sexual activity appeared diminished particularly in relation to reduced FT.

Familial combined pituitary hormone deficiency is a rare endocrine disorder. We describe growth patterns of four children (3 females and 1 male) from two families with combined pituitary hormone deficiency. These children received growth hormone at ages ranging from 14.5 years to 19 years. While all the female siblings reached their target height, the male sibling was much shorter than mid pare...

im of the study: Rasayan drugs act inside the human body by modulating the neuro-endocrino-immune system. Vaajikaran rasayan is the special ategory of rasayan which investigate the reproductive system and enhance sexual function. Curculigo orchioides, Astercantha longifolia and ucuna pruriens are well known vajikaran rasayan herbs. The effect on sexual behaviour and reproductive parameters are ...
