Where does oogenesis and spermatogenesis occur?

Answer 1

oogenesis -- in the female ovary
spermatogenesis - in male testes

Answer 2

oogenesis in the female germ cell - Oogenesis or rarely oögenesis is the creation of an ovum (egg cell) in the ovarian follicle of the ovary.

spermatogenesis in the male germ cell - Spermatogenesis is the process by which male gametogonia develop into mature spermatozoa, the mature male gametes, in many sexually reproducing organisms. In mammals it occurs in the male testes and epididymis in a stepwise fashion, and for humans takes approximately 64 days.

Oogenesis
From Wikipedia, the free encyclopedia

Oogenesis or rarely oögenesis is the creation of an ovum (egg cell) in the ovarian follicle of the ovary.

In mammals, oogonial transformation into oocytes (oocytogenesis) is completed either before or shortly after birth. Further development comes to a rest during prometaphase I of meiosis, known as the Dictyate stage, until puberty triggers oogenesis. In Ascaris, the oocyte does not even begin meiosis until the sperm touches it.

Oogenesis is the process in which the primary oocyte turns to an ovum undergoing meiosis. At first you start with a diploid oocyte called the primary oocyte. Meiosis I occurs in which synapsis occurs and tetrads form and crossing over as well and this becomes the secondary oocyte and the first polar body. Then the secondary oocyte undergoes meiosis II and is a haploid called ootid and also a second polar bodies as well as the first polar bodies that undergoes meiosis II as well and turns into two more polar bodies making a total of 3 polar bodies that disintegrate leaving only the ootid which undergoes maturation and turns to the ovum.

It is interesting to note that such an important process in animal life cycles is done completely without the aid of spindle-coordinating centrosomes.

In mammals it occurs in the male testes and epididymis in a stepwise fashion, and for humans takes approximately 64 days. Spermatogenesis is highly dependent upon optimal conditions for the process to occur correctly, and is essential for sexual reproduction. It starts at puberty and usually continues uninterrupted till death, although a slight decrease can be discerned in the quantity of produced sperm with increase in age.

Spermatogenesis is the process by which male gametogonia develop into mature spermatozoa, the mature male gametes, in many sexually reproducing organisms.

Answer 5

oogenesis occurs in the ovary
spermatogenesis is in the testes

Answer 6

Where Does Oogenesis Take Place

Answer 7

Oogenesis occurs in female gonads i.e ovaries.. Spermatogenesis occurs in male gonads i.e testes..

Answer 8

Sounds like a sex thing.

Answer 9

The second one sounds like it occurs down there.. But I dunno about the first...
