in which gland does final maturation of a sperm cell occur?
sertoli cells
the female pronucleus is the female egg cell once it has become a haploid cell, and the male pronucleus forms when the sperm enters into the female egg. while the sperm develops inside of the male testes, the sperm does not become a pronucleus until it decondenses quickly inside of the female egg. when the sperm reaches the female egg, the sperm loses its outside membrane as well as its tail. the sperm does this because the membrane and the tail are no longer needed by the female ovum. the purpose of the cell membrane was to protect the dna from the acidic vaginal fluid, and the purpose of the tail of the sperm was to help move the sperm cell to the egg cell. the formation of the female egg is asymmetrical, while the formation of the male sperm is symmetrical. typically in a female, meiosis starts with one diploid cell and becomes one ovum and three polar bodies. in a male, meiosis starts with one diploid cell and ends with four sperm. in mammals, the female pronucleus starts in the center of the egg before fertilization. when the male pronucleus is formed, after the sperm cell reaches the egg, the two pronuclei migrate towards each other. however, in brown alga pelvetia, the egg pronucleus starts in the center of the egg before fertilization and remain in the center after fertilization. this is because the egg cells of brown alga pelvetia, the egg pronucleus is anchored down by microtubules so only the male pronucleus migrates towards the female pronucleus.

in "in vitro" fertilization (ivf), induction of final maturation avails for egg retrieval when the eggs are fully mature.









































in ivf, final maturation induction is preceded by controlled ovarian hyperstimulation. it is suggested that there should be a size of ovarian follicles of at least 15 mm, and serum estradiol level of 0.49 nmol/l before commencing final maturation induction. there are better prospects at a follicle size of 18 mm and serum estradiol level of 0.91 nmol/l.
