Reproduction in adult humans is the biological process by which new individuals are created. It involves the fusion of gametes, typically sperm from a male and an egg from a female, to form a zygote. This process is initiated by sexual intercourse, during which sperm are deposited into the female reproductive tract. Following ovulation, if fertilization occurs, the zygote implants in the uterus and develops into an embryo and then a fetus. Gestation typically lasts around 40 weeks.

The male reproductive system produces sperm continuously after puberty. The female reproductive system produces eggs and undergoes a monthly cycle called the menstrual cycle, which prepares the uterus for potential pregnancy. Hormones play a crucial role in regulating these processes, including the production of gametes, ovulation, and the maintenance of pregnancy.

Fertility can be influenced by various factors, including age, health, lifestyle, and genetics. Assisted reproductive technologies (ART) exist to help individuals or couples who experience difficulties conceiving naturally. These technologies can include in vitro fertilization (IVF) and intrauterine insemination (IUI).

Reproduction is a fundamental aspect of human existence, ensuring the continuation of the species. It is a complex process involving intricate physiological and hormonal mechanisms. Understanding these processes is important for reproductive health and family planning.
