There is more than one way to contracept.
The Mechanisms of Male Contraception
Exploring the landscape of male contraception reveals multiple biological targets for reversible inhibition of fertility, each leading to contraceptives with unique profiles. To facilitate a deeper understanding of these targets and their potential, this page offers links to comprehensive primers that illustrate both the target categories and the prospective functional mechanisms of related contraceptives.
Spermatogenesis
Spermatogenesis is the creation of mature sperm from germ cells, and presents unique opportunities with respect to male methods of contraception. This primer provides more details.
Sperm Transport
Preventing sperm from being transported out of the reproductive tract is the basis of vasectomy, one of the only existing forms of male contraception, and the ability to reversibly block this process represents huge potential for new, additional male contraceptives.
Sperm Motility
One key feature of sperm is their ability to swim through the reproductive tract. This ability, or sperm motility, is one of the most exciting targets of male contraception. This prime provides additional details.
Fertilization
Fertilization is the joining of human egg and sperm to create a zygote, and is a prime target for male contraception because of its place as the last step in the reproductive chain. Learn more in this primer.
