Heat stress (HS) often blamed for suboptimal reproductive efficiency and is a worldwide problem, which inflicts heavy economic losses reflected in limiting the breeding season of rabbits to be normally from September to May in northern hemisphere and subtropical regions. The present experiment was conducted to study the effect of summer heat stress and the alleviating effect of some antioxidant...

Male reproductive fitness is strongly affected by seminal fluid. In addition to interacting with the female environment, seminal fluid mediates important physiological characteristics of sperm, including capacitation and motility. In mammals, the male reproductive tract shows a striking degree of compartmentalization, with at least six distinct tissue types contributing material that is combine...

With regard to using this technique for diagnosing seminal vesicle tumors, several technical skills are worth noting. Firstly, the orifice to the verumontanum or seminal vesicle could occasionally not be found. As illustrated in Figure 1a, it was not possible to locate the orifice of the verumontanum when the seminal vesicle tumor had invaded the urethra, but it was easy to obtain tumor tissue ...

KOZEK, W. J. 1975. Trichinella spiralis: Morphological characteristics of male and female intestine-infecting larvae. Experimental Parasitology 37, 380-387. The sex of encysted and excysted intestine-infecting T. spiralis larvae can be distinguished by the following morphological characteristics: the male larva has a long (approx 50 pm) rectum, and the anterior part of the testis is curved post...

Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...
