Primordial, secondary, tertiary, and antral are the basic steps in a developing oocyte
During the fetal period, each primary oocyte achieves a diameter of 20 micrometers and is surrounded by a single, Spermatozoa Transport and Maturation.
LH Leutenizing hormone- it stimulates the release of the oocyte into the fallopian tube, i.e. ovulation. [Do not confuse with FSH- follicle stimulating hormone, which stimulates the growth/maturation of the follicle containing the oocyte IN the Ovary.]

Any oogonia that has arrested itself in meiosis I prophase-dipotene on the onset of OMI (oocye maturation inhibition) hormone in the 3rd month of pregnancy and there after is a primary oocyte. On the urge of Leutinizing hormone which induces the pre-ovulatory phase, the primary oocyte completes meiosis I and arrests itself in meiosis II metaphase, which would only be completed if fertilization occurs, otherwise it will degenrate in 24 hours. On the completion of meiosis I, a SECONDARY oocyte and forst polar body is going to be formed.

oogenesis is the development and maturation of the ovum, a process which occurs within the female reproductive system.

Defination of maturation?
Human oocytes mature immediately after the surge of LH which occurs at ovulation. The surge of LH causes maturation of the oocyte which is the completion of the first division of meiosis.
ovum is the product after the secondary oocyte fuses with sperm
What is maturation? Maturation is the process of becoming mature or the emergence of personal and behavioral characteristics through growth process. Maturation is when a child matures.
The last 7 months of prenatal development typically involve rapid growth and maturation of the fetus. Organs and systems continue to develop and reach functional levels, and the fetus gains weight in preparation for birth. During this time, the fetus also practices breathing and swallowing to prepare for life outside the womb.
