  2. Oogenesis - Wikipedia

    en.wikipedia.org/wiki/Oogenesis

    Oogenesis (/ ˌ oʊ. ə ˈ dʒ ɛ n ɪ s ɪ s /) or ovogenesis is the differentiation of the ovum (egg cell) into a cell competent to further develop when fertilized. [1] It is developed from the primary oocyte by maturation.

  3. Folliculogenesis - Wikipedia

    en.wikipedia.org/wiki/Folliculogenesis

    The primary role of the follicle is oocyte support. From the whole pool of follicles a woman is born with, only 0.1% of them will rise ovulation, whereas 99.9% will break down (in a process called follicular atresia).

  4. Germ cell - Wikipedia

    en.wikipedia.org/wiki/Germ_cell

    Gametogenesis, the development of diploid germ cells into either haploid eggs or sperm (respectively oogenesis and spermatogenesis) is different for each species but the general stages are similar. Oogenesis and spermatogenesis have many features in common, they both involve: Meiosis; Extensive morphological differentiation

  5. Ovarian follicle - Wikipedia

    en.wikipedia.org/wiki/Ovarian_follicle

    An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries.It secretes hormones that influence stages of the menstrual cycle.At the time of puberty, women have approximately 200,000 to 300,000 follicles, [1] [2] each with the potential to release an egg cell (ovum) at ovulation for fertilization. [3]

  6. Ovulation - Wikipedia

    en.wikipedia.org/wiki/Ovulation

    Ovulation occurs about midway through the menstrual cycle, after the follicular phase, and is followed by the luteal phase.Note that ovulation is characterized by a sharp spike in levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), resulting from the peak of estrogen levels during the follicular phase.

  7. Gametogenesis - Wikipedia

    en.wikipedia.org/wiki/Gametogenesis

    Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis.

  8. Follicular atresia - Wikipedia

    en.wikipedia.org/wiki/Follicular_atresia

    Histological view of an ovarian follicle. The egg is located within the smaller ring. Follicular atresia refers to the process in which a follicle fails to develop, thus preventing it from ovulating and releasing an egg. [1]
