The boar has a tremendous impact on the reproductive efficiency of the swine breeding herd. Depending on the collection frequency and insemination dose, semen from a single boar can be used to breed between 750 and 1000 sows per year. As a result, reproductive failure of a single male influences a large number of sows. Consequently, a thorough understanding of the basic aspects of male reproduc...

Reproductive efficiency is a crucial factor in the economic viability of small ruminant exploitation. In spite this, few producers utilize available reproductive technologies related to hormonal interaction, which are vital for sustainability their operations. Therefore, this review aimed investigate potential effects alterations and hormone interactions during pregnancy lactation determine adv...

The 100,000th scientific article on the subject of spermatozoa was recently published. Many studies have evaluated the characteristics of this important cell leading to great discoveries. Since its first observation and description in 1677, many important characteristics have been described regarding this highly fascinating gamete. In this review, our objective has been to provide a historical ...

It is well established that, over the course of development, hormones shape the vertebrate brain such that sex specific physiology and behaviors emerge. Much of this occurs in discrete developmental windows that span gestation through the prenatal period, although it is now becoming clear that at least some of this process continues through puberty. Perturbation of this developmental progressio...

Background: Rodents with short reproductive cycle length are the best model for investigation of physiology and molecular aspects of reproductive biology. This study aimed to establish a correlation between histological changes of uterus and ovaries with the vaginal smear. Materials and Methods: 6-8 weeks old virgin Female NMRI mice were submitted to the vaginal smear collection and observed us...

Abstract Accumulating evidence has shown that Wnt signaling is deeply involved in male reproductive physiology, and malfunction of the signal path can cause pathological changes genital organs sperm cells. These abnormalities are diverse manifestation have been constantly found knockout models studies. Nevertheless, most research solely focused on a certain factor pathway, there few reports ove...
