Production takes place in the testes which are housed in the temperature regulating scrotum, immature sperm then travel to the epididymis for development and storage. The first category is sperm production and storage. The major reproductive organs of the male can be grouped into three categories. The primary direct function of the male reproductive system is to provide the male gamete or spermatozoa for fertilization of the ovum.

The human male reproductive system is a series of organs located outside of the body and around the pelvic region of a male that contribute towards the reproductive process. Main article: Male reproductive system (human) In addition to differences in nearly every reproductive organ, numerous differences typically occur in secondary sexual characteristics and in sexual and parental behaviors. Humans have a high level of sexual differentiation. One important type of parental care is the use of the mammary glands in the female breasts to nurse the baby. Humans babies and children are nearly helpless and require high levels of parental care for many years. Labor consists of the muscles of the uterus contracting, the cervix dilating, and the baby passing out the vagina. Gestation ends with birth, the process of birth in known as labor. Upon successful fertilization and implantation, gestation of the fetus then occurs within the female's uterus for approximately nine months, this process is known as pregnancy in humans.

The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum. During this process, the erect penis of the male is inserted into the female's vagina until the male ejaculates semen, which contains sperm, into the female's vagina. Human reproduction takes place as internal fertilization by way of intercourse.

However, there is a great diversity of physical adaptations as well as reproductive strategies in every group of vertebrates. Most other vertebrate animals have generally similar reproductive systems consisting of gonads, ducts, and openings. Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases. The major organs of the human reproductive system include the external genitalia (penis and vulva) as well as a number of internal organs including the gamete producing gonads (testicles and ovaries). These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring. Unlike most organ systems, the sexes of differentiated species often have significant differences. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. The reproductive system is a system of organs within an organism which work together for the purpose of reproduction.
