Previous studies have found that smoking is associated with decreased male fertility via altering the quality of semen. However, the mechanism by which cigarette smoking affects semen quality remains to be fully elucidated. Heavy smoking-induced DNA damage has been reported to correlate with abnormal spermatozoa and male infertility. It has been reported that, in response to DNA damage, activat...

The evaluation of sperm quality in the laboratory is essential to improve efficiency assisted reproduction. As other species, for dog there are reports that prolonged contact with some components seminal plasma associated decreased motility and viability. Thus, centrifugation a technique widely used concentrate spermatozoa eliminate supernatant. purpose this study was evaluate effect double laye...

chronic inflammatory demyelinating polyneuroradiculopathy (cidp) is an immune mediated disorder characterized by progressive developing or relapsing symmetrical motor or sensory symptoms in more than one limb over a period of two months. achalasia, as a primary esophageal motility disorder, is also characterized by increasing the tone of lower esophageal sphincter, absence or incomplete sphinct...

Although the development of semen cryopreservation in the African elephants (Loxodonta africana) has been accomplished, effective procedures for cryopreservation of Asian elephant (Elephas maximus) spermatozoa have not been established. In the present study, we investigate the freezing methods for conservation of Asian elephant spermatozoa under field conditions and identify the most suitable f...

BACKGROUND There is clinical evidence to show that sperm DNA damage could be a marker of sperm quality and extensive data exist on the relationship between DNA damage and male fertility status. Detecting such damage in sperm could provide new elements besides semen parameters in diagnosing male infertility. We aimed to assess sperm DNA fragmentation and oxidation and to study the association be...

Forward motility stimulating factor (FMSF), a glycoprotein isolated from buffalo serum, binds to the surface of the mature sperm cells to promote their progressive motility. This article reports the mode of signal transduction of this extracellular factor in goat sperm. The mechanism was investigated by assaying intracellular second messenger level and forward motility in presence of different ...

Objective: In this study we investigated the effects of spearmint (Mentha spicata Labiatae) on the reproductive system, fertility and number of offspring in adult male rats. Materials and Methods: Adult Wistar male rats in one control (C) and three experimental groups (I, II and III) received 0, 10, 20 and 40 mg/kg spearmint extract orally for 45 days, respectively.  Following this treatment, t...
