The primary follicle contains the primary oocyte, which gets surrounded by a layer of granulosa cells. Cell division in the primary oocyte... View Article
The second polar body is formed as a result of unequal meiosis II in the secondary oocyte along with the ovum. The second polar body contains a... View Article
During ovulation, the Graafian follicle ruptures and releases secondary oocytes. Ovulation occurs in the middle of the cycle and is induced by an... View Article
Oogonia are diploid. Oogonia undergo mitosis to produce Spermatocytes. Spermatocytes undergo meiosis to produce sperms. Also Check: Why Is... View Article
Oogonia are the gamete mother cells. The primary follicle consists of a primary oocyte, which is arrested at the diplotene stage of prophase I of... View Article
Follicle-stimulating hormone or FSH stimulates the growth and development of ovarian follicles. FSH is secreted by the anterior pituitary on... View Article
Spermatocytes are formed from spermatogonia (immature germ cells), which undergo meiosis to give rise to male gametes or sperms (spermatozoa).... View Article
A secondary follicle is formed from the primary follicle as it gets surrounded by more layers of granulosa cells and a theca layer is formed... View Article
Primordial follicles contain diploid primary oocytes surrounded by a single layer of granulosa cells. It is a fundamental reproductive unit of... View Article
Spermatogenesis is triggered by androgens such as testosterone, FSH (follicle-stimulating hormone). Androgens are mainly secreted by Leydig cells... View Article
When one sperm penetrates the zona pellucida, it brings about structural changes in the membrane that prevents other sperms from entering the... View Article
A pair of ovaries are present in females below the fallopian tubes. Oogonia or female gamete mother cells are located in the cortex part of... View Article
The primary oocyte is diploid and formed from oogonia after mitosis, whereas the secondary oocyte is formed from the primary oocyte after meiosis... View Article
Yes, polar bodies have chromosomes but contain very little cytoplasm and do not have the ability to be fertilised. The first polar body is formed... View Article
Fifty primary oocytes give rise to 50 eggs. A primary oocyte undergoes meiosis I to produce a secondary oocyte and a polar body. The secondary... View Article
Oogenesis starts during the embryonic stage itself. There are around two million primary oocytes present in the ovaries at the time of birth in... View Article
Luteinizing hormone secreted by the pituitary gland stimulates the rupture of the follicle for ovulation. There is an LH surge just before... View Article
