  2. Male reproductive system - Wikipedia

    en.wikipedia.org/wiki/Male_reproductive_system

    The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.

    Male reproductive system. The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. [3] Penile shrinkage due to low ...

  4. List of related male and female reproductive organs - Wikipedia

    en.wikipedia.org/wiki/List_of_related_male_and...

    This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.

  5. Human reproduction - Wikipedia

    en.wikipedia.org/wiki/Human_reproduction

    The male reproductive system contains two main divisions: the testicles where sperm are produced, and the penis where semen is ejaculated through the urethra. In humans, both of these organs are outside the abdominal cavity. Having the testicles outside the abdomen facilitates temperature regulation of the sperm, which require specific ...

  6. Human penis - Wikipedia

    en.wikipedia.org/wiki/Human_penis

    This means that in the event of a rival male's sperm occupying the reproductive tract of a female, the human penis is able to displace the rival sperm, replacing it with his own. [42] Semen displacement has two main benefits for a male. Firstly, by displacing a rival male's sperm, the risk of the rival sperm fertilising the egg is reduced. [43]

  7. Seminiferous tubule - Wikipedia

    en.wikipedia.org/wiki/Seminiferous_tubule

    Spermatogenesis, the process for producing spermatozoa, takes place in the seminiferous tubules.During spermatogenesis, the DNA of spermatogenic cells in the seminiferous tubules is subject to damage from such sources as reactive oxygen species. [1]

  8. Spermatogenesis - Wikipedia

    en.wikipedia.org/wiki/Spermatogenesis

    Spermatogenesis produces mature male gametes, commonly called sperm but more specifically known as spermatozoa, which are able to fertilize the counterpart female gamete, the oocyte, during conception to produce a single-celled individual known as a zygote.

  9. Sex organ - Wikipedia

    en.wikipedia.org/wiki/Sex_organ

    A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
