Increasing paternal age and ejaculatory abstinence length negatively influence the intracytoplasmic sperm injection outcomes from egg‐sharing donation cycles
22 Nov 2019
Abstract excerpt
BACKGROUND: The paternal role in embryogenesis is much more than providing a haploid genome. The spermatozoa have crucial roles related to embryogenesis' epigenetic regulation, fusion of gametes, and cleavage, which may influence intracytoplasmic sperm injection outcomes. OBJECTIVES: To study whether paternal age, length of ejaculatory abstinence and semen parameters influence the outcomes of intracytoplasmic...
