Assessment of Sperm Apoptosis and Semen Quality in Infertile Men-Meta Analysis

Dear Editor, Apoptosis is the programmed cell death that occurs because of the DNA fragmentation which is seen in the sperm of infertile men. There are two different mechanisms: Intrinsic (mitochondrial) pathway and extrinsic pathway which is done by cell receptors. Apoptosis has a significant relation with infertility of men. The more immature the testicle, the more apoptosis will happen. Stan...

Onm-6: Apoptosis and the Quality DecreaseOf Sperm Parameters in Infertile Men.

Sperm chromatin structure, semen quality and lead in blood and seminal fluid of infertile men.

BACKGROUND Exposures to lead above the threshold value of 50-60 μg/dL have been linked to diminished semen quality parameters. Worldwide, the lead exposure has been diminished during the last years. Therefore, it has become of a great concern to examine the effects of lead exposures on semen quality at low levels of exposure. OBJECTIVE To evaluate the effect of low level (<20 μg/dL) blood lea...

Significant Correlation between High-Risk HPV DNA in Semen and Impairment of Sperm Quality in Infertile Men

Objective Background: Human papillomavirus (HPV) is a DNA virus that causes sexually transmitted infection (STI). Recent reports have suggested that HPV may affect sperm parameters and lead to male infertility. This study is aimed to evaluate the correlation between seminal high-risk HPV infection and impairment of sperm quality in Iranian infertile men. MaterialsAndMethods Materials and Method...

Varicoceles affect semen quality of infertile men in Southern China

The association of varicoceles with infertility is well established, but the exact effect of varicoceles on semen quality among patients with infertility is still poorly known. The study aimed to examine the prevalence of varicoceles among Chinese men with infertility and to examine the factors associated with semen quality.This was a cross-sectional study of 5447 male patients treated for infe...
