Cigarette smoking remains a major factor in reducing semen quality in adult men, a new study has verified, despite significant changes to the criteria that laboratories worldwide are supposed to use to evaluate semen samples and assess fertility.
Examination of sperm function through proteomics has the potential to improve on conventional semen analysis in the workup of male infertility. Differentially expressed proteins may serve as novel biomarkers in the identification of bilateral varicocele and may help urologists identify better options for clinical management of infertile men.
