objective(s): sugar cane molasses is a commonly used ingredient in several food products. contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. however, little evidence exists that examines the effects of molasses on the different physiological systems. this study investigated the effects of sugar cane molasses on various physiological syste...

Female and male reproductive tracts are of interest sites to study of immune system because they encounter specific infections such as those are sexually transmitted. Furthermore, female reproductive tract is in close contact with allogenic sperms and transmitted microorganisms during intercourse and semi allogenic fetus during pregnancy. In mammals, there are two types of immune responses, the...

Chlorpyrifos (CPF) is a broad spectrum organophosphate pesticide used for agricultural health purposes. Its principal mechanism of toxicity is the inhibition of acetylcholinesterase. The purpose of present study was to investigate the effects of CPF on testicular tissue and sperm parameters in male rats. Thirty-two healthy male rats were divided into two groups: a CPF-exposed group and a contro...

Estrogen is synthesized in the male reproductive system and is found in high concentrations in rete testis and seminal fluids. This luminal estrogen targets estrogen receptors (ER) along the male reproductive tract, and in particular the efferent ductules, where ERalpha is abundant. However, both ERalpha and ERbeta are found in various regions of the male reproductive tract. The transgenic ER k...

background: high content of phospholipids in testes and epididymis is involved in regulation of spermatogenesis. on the other side, it makes testes susceptible to oxidative stress due to lipid peroxidation, which alters the normal mechanism of spermatogenesis. objective: in the present investigation, antioxidant effects of ethanolic extracts of parsley, lettuce and brahmi were tested against d-...

background: besides the well-known adverse effects of valproate (vpa), disorders related to male reproductive functions have been reported. furthermore, only a limited number of previous studies have reported the relationship between vpa dose and impairment of the hormonal axis and semen quality. a patient with reversible changes that occurred in the sperm parameters after a dose increment of v...

Reproductive behavior in male rodents is made up of anticipatory and consummatory elements which are regulated in the brain by sensory systems, reward circuits and hormone signaling. Gonadal steroids play a key role in the regulation of male sexual behavior via steroid receptors in the hypothalamus and preoptic area. Typical patterns of male reproductive behavior have been characterized, howeve...
