At fertilization the secondary oocyte completes its second meiotic division
ovum is the product after the secondary oocyte fuses with sperm
polar body
The purpose of fertilization is the first step in the reproduction of new offspring, which contributes to the longevity of different species, so that they do not become extinct.i.e. human fertilization occurs when a haploid sperm cell & haploid secondary oocyte produce a diploid nucleus
Oocyte retrieval for in vitro fertilization from a donor by means of a follicle puncture cpt code?
first polar body
The fallopian tubes also knows as the uterine tubes transport the secondary oocyte or the fertilized egg to the uterus.
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.
