sperm maturation

sperm maturation

The process in which primitive spermatozoa (sperm cells) grow and develop, eventually becoming capable of independent motility of fertilising a viable ovum (egg).

These three biomarkers are assimilated with the sperm membrane developing through late steps of spermatogenesis in the testis and sperm maturation in epididymis and they improve capacitation which is involved in fertilization (25, 26).
Sperm mitochondrial and nuclear DNA are potential targets of attack by ROS [35] which usually progress to sperm apoptotic events that are completed in the epididymis during sperm maturation and capacitation [32].
Increased BMI has been suggested to negatively affect spermatogenesis and the molecular structure of germ cells in the testis and sperm maturation in the epididymis [6, 7], consequently resulting in reduced sperm quality and male subfertility [8-12].

The ROS, under physiological conditions, play important roles in different processes necessaries for sperm maturation and function, such as capacitation, hyperactivation, acrosome reaction and sperm-oocyte fusion, allowing proper fertilization process [19, 21, 40].
The research team observed that although lower water temperatures were correlated primarily with spermatogenesis, maturing oocytes were present throughout the winter study period and that the mean date for sperm maturation occurred before the mean date of oocyte maturation.
