  2. Gonad - Wikipedia

    en.wikipedia.org/wiki/Gonad

    A gonad, sex gland, or reproductive gland [1] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [2] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells

  3. Testicle - Wikipedia

    en.wikipedia.org/wiki/Testicle

    Male gonad (testes, left) and female gonad (ovaries, right) Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. [1] Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's ...

  4. Male reproductive system - Wikipedia

    en.wikipedia.org/wiki/Male_reproductive_system

    Reproductive sex organs for both male and female are derived from the same embryonic tissues and are considered homologous tissues or organs. [4] Testosterone. After the testes have differentiated, male sex hormones, called androgens, are secreted from interstitial cells (cells of Leydig).

    The male external genitalia include the penis and the scrotum. The female external genitalia include the clitoris, the labia, and the vestibule, which are collectively called the vulva. External genitalia vary widely in external appearance among different people.

  6. Development of the gonads - Wikipedia

    en.wikipedia.org/wiki/Development_of_the_gonads

    The gonadal ridge, in turn, develops into a gonad. This is a testis in the male and an ovary in the female. At first, the mesonephros and gonadal ridge are continuous, but as the embryo grows the gonadal ridge gradually becomes pinched off from the mesonephros. However, some cells of mesonephric origin join the gonadal ridge.

  7. Sex cords - Wikipedia

    en.wikipedia.org/wiki/Sex_cords

    Sex cords are embryonic structures which eventually will give rise (differentiate) to the adult gonads (reproductive organs). [1] They are formed from the genital ridges - which will develop into the gonads - in the first 2 months of gestation (embryonic development) which depending on the sex of the embryo will give rise to male or female sex ...

  8. Sex organ - Wikipedia

    en.wikipedia.org/wiki/Sex_organ

    The primary sex organs are the gonads, a pair of internal sex organs, which diverge into testicles following male development or into ovaries following female development. [8] As primary sex organs, gonads generate reproductive gametes containing inheritable DNA. They also produce most of the primary hormones that affect sexual development, and ...

  9. Gubernaculum - Wikipedia

    en.wikipedia.org/wiki/Gubernaculum

    As the scrotum and labia majora form in males and females respectively, the gubernaculum aids in the descent of the gonads (both testes and ovaries). [3] The testes descend to a greater degree than the ovaries and ultimately pass through the inguinal canal into the scrotum. [3] The mechanism of this movement is still debated. [3]
