Semen cryopreservation is an important tool for artificial breeding, species conservation and
human reproductive medicine. However, sublethal freezing damage remains an important …

Before the process of fertilization, spermatozoa necessitate a period of residence in the
female reproductive environment, and undergo a sequence of physiological and …

Once in the female reproductive tract, spermatozoa undergo several modifications to acquire
their complete fertilizing ability. Interactions between the oviductal fluid (OF) and gametes …

Low temperatures during cryopreservation activate a cascade of changes, which may lead
into irreversible damage and reduction of the fertilization potential, including the process of …

The aim of this study was to evaluate the effect of resveratrol supplementation of semen
extender on fertility parameters of frozen-thawed buffalo sperm. After the initial semen …

The aim of this study was to investigate the dynamic changes that ram sperm experience
during in vitro capacitation before and after cryopreservation. Using flow cytometry and …

The objective of this study was to determine the mechanism by which RU 486 (mifepristone)
protects sperm to undergo premature capacitation during cryopreservation. For this, semen …

Cryoinjury and protein changes are a consequence of cryopreservation and may have a
negative impact on sperm quality regarding motility, viability and fertilizing ability. However …

Male infertility refers to the inability of a man to achieve a pregnancy in a fertile female. In
more than one-third of cases, infertility arises due to the male factor. Therefore, developing …

Before fertilization, spermatozoa must undergo a process called capacitation in order to fulfill
their fertilization potential. This includes a series of structural, biochemical, and functional …
