Knowra Human reproductive system Human reproductive system The organs and structures that produce human gametes and enable fertilization, pregnancy, and birth. It includes male and female reproductive anatomy, which differs in structure and reproductive roles.
Gonad : An organ that produces gametes and sex hormones. Ovaries and testes are the system’s primary reproductive organs.
Spermatogenesis : The process by which germ cells develop into sperm in the testes. It describes how the male reproductive system continually produces gametes.
Infertility : A condition in which pregnancy does not occur after a period of regular unprotected sex, or a person cannot carry a pregnancy. It can arise from problems affecting gametes, reproductive organs, or their function.
Male reproductive system : The organs and structures that produce sperm and support their delivery for reproduction. It is the sperm-producing anatomical system within the broader human system.
Gamete : A reproductive cell, such as an egg or sperm, that carries one set of chromosomes. Eggs and sperm are the cells this system produces for reproduction.
Oogenesis : The process by which egg cells develop in the ovaries. It explains egg development and the limited supply of cells available for ovulation.
Assisted reproductive technology : Medical procedures that handle eggs, sperm, or embryos to help achieve pregnancy. These treatments work around some barriers to natural fertilization or conception.
Female reproductive system : The organs and structures that produce eggs and support fertilization, pregnancy, and birth. It is the egg-producing and gestational anatomical system within the broader system.
Ovary : A female gonad that produces egg cells and hormones, including estrogen and progesterone. It produces eggs and supports hormonal regulation of the reproductive cycle.
Menstrual cycle : A recurring hormonal cycle that prepares the ovaries and uterus for possible pregnancy. Its ovarian and uterine changes coordinate ovulation with preparation for implantation.
