Abstract
Background: Currently, approximately half of all pregnancies worldwide are unintended. Contraceptive use significantly reduces the risk of unintended pregnancy; however, options for men are particularly limited. Consequently, efforts are underway to develop novel, safe, and effective male contraceptives.
Results: This review discusses research into emerging male contraceptive methods that either inhibit sperm production or impair sperm function. It focuses on those in the preclinical or early clinical stages of development.
Keywords: condoms; male contraception; spermatozoa; unintended pregnancy; vasectomy.
