Assisted reproductive technologies invoIving the use of spermatozoa and eggs for in vitro fertilization(IVF)have come as the solution for many infertile couples to become parents.However,in some cases,the use of ejacu...

The sperm nucleus is prone to sustain DNA damage before and after ejaculation.Distribution of the damage is not homogeneous,and the factors determining differential sensitivity among nuclear regions have not yet been ...
Sperm DNA damage is recognized as an important biomarker of male infertility. To investigate this, sperm DNA damage was assessed by the sperm chromatin dispersion (SCD) test in semen and motile spermatozoa harvested...
This study was conducted to clarify the toxic effects of sertraline (SRT) on the reproductive system of male rats and to elucidate the underlying mechanisms. Rats were treated orally with SRT at doses of 5, 10, and ...
One of the major causes of defective sperm function is oxidative stress, which not only disrupts the integrity of sperm DNA but also limits the fertilizing potential of these cells as a result of collateral damage to ...
We aimed to investigate the role of thioredoxin reductase (TR) and inducible heat shock protein 70 (iHsp70) and their relationship with sperm quality in varicocele (VAR) patients. Semen samples were obtained fro...
Several studies have suggested that stress and ageing exert inhibitory effects on rat Leydig cells. In a pattern similar to the normal process of Leydig cell ageing, stress-mediated increases in glucocorticoid levels ...
It is well known that transit through the epididymis involves an increase in the compaction of sperm chromatin, which acquires fully condensed status at the caput epididymidis. The purpose of this study was to compare...
A wide variety of techniques for the preparation of sperm are currently available, of which the most commonly employed are densitygradient centrifugation (DGC) and swim-up (SUP). To date, these methods appear to b...
