Proanthocyanidins are a class of polyphenols found in a variety of plants that have antioxidant activity in vitro, which is stronger than vitamin C or vitamin E. Several studies have been...
Little is known about the effects of weight loss surgery on male reproductive health. This study will investigate the effect of bariatric surgery on male infertility by evaluating sexual h...
The proposed research aims to study the effects of antioxidant therapy, commonly used in male infertility treatment, on semen analysis. Patients presenting with male infertility, who are f...
The objective of this study is to determine if concentrations of maraviroc in semen exceed the 50% and 95% inhibitory concentrations of HIV during the dose interval. The secondary objecti...

MicroRNAs (miRNAs) have recently been shown to be important for spermatogenesis; both DROSHA and Dicer1 KO mice exhibit infertility due to abnormal miRNA expression. However, the roles of individual m...
Conception rate with the use of sexed semen is lower than that with the use of conventional semen, posing a major problem in the dairy industry. The aim of this study was to understand the risk factor...
In recent decades, the capability of mankind spermatogenesis is declining due to various threats. Anthocyanins as colorful polyphenols possess beneficial functions for the organisms, including Leydig ...

Infertility affects about 15% of all couples worldwide. Male factors such as decreased semen quality contribute to around 40% of the cases. Recent reviews have shown that different foods and nutrients...
A scientific or medical discipline concerning the study of male reproductive biology, diseases of the male genital organs, and male infertility. Major areas of interest include ENDOCRINOLOGY; SPERMATOGENESIS; semen analysis; FERTILIZATION; CONTRACEPTION; and CRYOPRESERVATION.
The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.
A condition characterized by the complete absence of SEMEN. This disorder should be differentiated from AZOOSPERMIA, absence of sperm in the semen.
The process by which semen is kept viable outside of the organism from which it was derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
A condition of suboptimal concentration of SPERMATOZOA in the ejaculated SEMEN to ensure successful FERTILIZATION of an OVUM. In humans, oligospermia is defined as a sperm count below 20 million per milliliter semen.
