The two ovaries contain hundreds of undeveloped female sex cells called egg cells or ova(the plural of ovum). Women have these cells in their bodies from birth - whereas men produce new sperm continually. 两个卵巢包含数百个未充分发育的雌性性细胞,这些细胞称为卵细胞或卵子。女性出生时就带有这些...
The female reproductive system is a complex system of external and internal organs that produce eggs that are necessary for reproduction. One egg is prepared for fertilization every month. If that egg isn't fertilized with sperm, you'll get your period — the result of your uterus shedding the...

Oocytes are essential cells capable of developing into eggs, which can be matured either in vivo or in vitro. These cells progress through three distinct stages: primary oocytes, secondary oocytes and mature oocytes [126]. Primary oocytes, which are diploid cells in the initial stage of meiosis,...

As they move forward into sec- ondary oocytes, they become haploid cells after the first meiosis and contain fewer nutrients and mRNA [127]. Finally, mature eggs undergo the second meiosis and become fully functional haploid cells capable of fertili- zation. In terms of in vitro culture, ...

BUT these are not "true eggs" yet, and will never complete meiosis (a special type of cell division) and become "true eggs" unless OR until they are first fertilized by a sperm. Within the ovary, a follicle consists of one potential egg cell surrounded by special cells to nourish and ...
