The primary function of the reproductive system is to ensure the continuation of a species through the production and support of offspring. In humans, the reproductive system facilitates sexual reproduction, which includes the production of gametes (sperm in males and ova in females), fertilization, and gestation. In females, the reproductive system also includes structures that support pregnancy, childbirth, and lactation. Additionally, the reproductive system plays a role in the regulation of hormones associated with sexual development and reproductive health. Overall, it is essential for not only reproduction but also for maintaining the genetic diversity of populations.
