NSAIDs can interfere with […] in females
ovulation (interfere with follicular rupture)
(no effect on male fertility)
MOA: cause feedback inhibition of GnRH from the hypothalamus
estrogens
negatively impact male fertility by causing ED, impaired ejaculation, and DNA fragmentation in sperm
SSRIs
can cause antegrade, anejaculation or decreased ejaculate volume
a-blockers (-zosins)
used to treat fungal infections and impairs steroidogenesis
ketoconazole
