Cryopreservation is the storage of biological material at subzero temperatures at which biochemical processes of cell metabolism and the biochemical reactions that lead to cell death are s...
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...
The objective of this study is to determine if concentrations of raltegravir in semen exceed the 50% and 95% inhibitory concentrations of HIV during the dose interval. The secondary objec...
Volunteers with normal and subnormal semen parameters receive a hormonal male contraceptive in order to investigate whether there are differences between normal and subnormal men in terms ...
Seminal cytokines were previously reported to adversely affect process of spermatogenesis and ultimately induce poor semen quality. However, association between both IL-6 and TNF-α and leukocytosperm...
In this study, at first, the reproductive consequences of sexed semen use were quantified and then the cost-benefit of sexed semen use on Iranian commercial dairy farms was evaluated. Retrospective da...
Perfluoroalkyl acids (PFAAs) have been suspected to act as endocrine disruptors and adversely affect human reproductive health. We aimed to investigate the association between PFAAs in blood and semen...
The relationship between the interleukin (IL)-11 levels and semen quality of infertile males remains unknown. In this study, 120 semen samples from 60 normozoospermic volunteers and 60 infertile males...
Systems for preserving semen in liquid form for artificial insemination were developed before cryopreserved semen became widely available in the 1960s. Advantages of liquid semen include reduced numbe...
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.
