Do heat stress and deficits in DNA repair pathways have a negative impact on male fertility?

abstract：:Prostaglandins (PG) E2 and F2 alpha are produced by the human corpus luteum in significant amounts and they are known to exert local luteotrophic and luteolytic effects respectively. The present study determined how PGE2 and PGF2 alpha are involved in the regulation of inhibin A, a granulosa cell-derived glycoprotein ...
