From one act of coitus a man can eject some 500 million sperm, yet a mere hundred survivors will reach the ovum. As a result anything less than 20 million sperm per ml of ejaculate significantly reduces the chance o...

Methacrylonitrile (MAN) is a widely used aliphatic nitrile and is structurally similar to the known rat carcinogen and suspected human carcinogen acrylonitrile (AN). There is evidence that AN is metabolized via the cytochrome P-450 (CYP) 2E1. Recently, we identified two biliary conjugates originating from the interaction of MAN and its epoxide with glutathione. Mercapturic acids formed via the ...

introduction toxoplasma gondii is one of the most important pathogen that has adverse effect on reproductive function. evidence acquisition recent studies revealed that infection with t. gondii not only affect female reproduction, also cause male reproductive impairment. in clinical studies, high prevalence of toxoplasmosis in sterile men has been reported. in animal models, toxoplasmosis is as...

The development and adult production of birdsong are subserved by specialized brain nuclei, including the robust nucleus of the archistriatum (RA), and its afferents originating in the caudal nucleus of the ventral hyperstriatum (HVc) and the lateral portion of the magnocellular nucleus of the anterior neostriatum (L-MAN). An in vitro brain slice preparation was used to characterize the electro...

This study tested whether synthesized human male pheromones increase the sociosexual behavior of men. Thirty-eight heterosexual men, ages 26-42, completed a 2-week baseline period and 6-week placebo-controlled, double-blind trial testing a pheromone "designed to improve the romance in their lives."

Mucinous cystic neoplasms (MCNs) of the pancreas in male patients are very rare. Though few cases of MCNs in male patients have been reported, it is difficult to reveal them preoperatively. The first patient was a 50-year-old man and was incidentally found to have a cystic mass of 51 mm in the tail of the pancreas. We performed a distal pancreatectomy. The second patient was a 73-year-old man, ...

Across taxa, strength and size are elementary determinants of relative fighting capacity; in species with complex behavioral repertoires, numerous additional factors also contribute. When many factors must be considered simultaneously, decision-making in agonistic contexts can be facilitated through the use of a summary representation. Size and strength may constitute the dimensions used to for...
