    en.wikipedia.org/wiki/Pampiniform_plexus

    The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.

  4. Bat ray - Wikipedia

    en.wikipedia.org/wiki/Bat_ray

    This ray has an essentially nonfunctional right ovary in addition to a right and left uteri that are able to function normally. Females can carry four size classes of ova. Larger bat rays will have an increased size and number of eggs. Bat rays have a low fecundity. Size at birth can range from 220–305 mm.

    One difference between the glans penis and the glans clitoridis is that the glans clitoridis packs nerve endings into a volume only about one-tenth the size of the glans penis. Therefore, the glans clitoridis has greater variability in cutaneous corpuscular receptor density (1-14 per 100× high-powered field) compared with the glans penis (1-3 ...

  6. Sex organ - Wikipedia

    en.wikipedia.org/wiki/Sex_organ

    Sex organs are typically differentiated into male and female types. In animals (including humans), the male sex organs include the testicles, epididymides, and penis; the female sex organs include the clitoris, ovaries, oviducts, and vagina. The testicle in the male and the ovary in the female are called the primary sex organs. [1]

    The ovary is differentiated into a central part, the medulla of ovary, covered by a surface layer, the germinal epithelium. The immature ova originate from cells from the dorsal endoderm of the yolk sac. Once they have reached the gonadal ridge they are called oogonia. Development proceeds and the oogonia become fully surrounded by a layer of ...

    The follicle is now 0.2 mm in diameter Early tertiary: The early tertiary follicle is arbitrarily divided into five classes. Class 1 follicles are 0.2 mm in diameter, class 2 about 0.4 mm, class 3 about 0.9 mm, class 4 about 2 mm, and class 5 about 5 mm. Late tertiary: Fully formed antrum, no further cytodifferentiation, no novel progress
