In the female, the paramesonephric ducts persist and undergo further development. The portions which lie in the genital cord [citation needed] fuse to form the uterus and vagina. This fusion of the paramesonephric ducts begins in the third month, and the septum formed by their fused medial walls disappears from below upward.
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.
The human female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. The reproductive system is immature at birth and develops at puberty to be able to release matured ova from the ovaries , facilitate their fertilization , and create a protective environment for the ...
Sexual differentiation includes development of different genitalia and the internal genital tracts and body hair plays a role in sex identification. [ 2 ] The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic ...
It has been suggested that embryos with a higher expression of Dmrt1 expression develop into males while embryos with a lower expression are led to female development. [1] In the mouse gonadal primordium, the genital ridge, which forms from intermediate mesoderm, becomes morphologically distinct at E10.5.
During the formation of the reproductive system, the paramesonephric ducts are formed just lateral to the mesonephric ducts in both female and male embryos 6 weeks after fertilization. During this time, primordial germ cells migrate from the yolk sac to the genital ridge; a region of mesenchyme arising from, and running parallel with, the ...
In embryology, the primordial phallus refers to the clitoris of a female or the penis in the male, particularly during embryonic development of the urinary and reproductive organs, before sexual differentiation is evident. This is also the case for the immature male analog, the immature glans penis.
Embryos are formed with Wolffian and Mullerian ducts, which will either become the male or female reproductive tract, respectively. [8] In a male embryo, the testicular cords will induce the development of the Wolffian duct into the vas deferens , epididymis and the seminal vesicle and cause the repression and regression of the Mullerian duct ...
