  2. Follicular phase - Wikipedia

    en.wikipedia.org/wiki/Follicular_phase

    The follicular phase, also known as the preovulatory phase or proliferative phase, [1] is the phase of the estrous cycle (or, in primates [2] for example, the menstrual cycle) during which follicles in the ovary mature from primary follicle to a fully mature graafian follicle.

  3. Folliculogenesis - Wikipedia

    en.wikipedia.org/wiki/Folliculogenesis

    Follicle ‘selection’ is the process by which a single ‘dominant’ follicle is chosen from the recruited cohort or wave for preferential growth. It has generally been documented to occur once in the early- to mid- follicular phase of the menstrual cycle, leading to ovulation. [1]

  4. Menstrual cycle - Wikipedia

    en.wikipedia.org/wiki/Menstrual_cycle

    The proliferative phase is the second phase of the uterine cycle when estrogen causes the lining of the uterus to grow and proliferate. [40] The latter part of the follicular phase overlaps with the proliferative phase of the uterine cycle. [31] As they mature, the ovarian follicles secrete increasing amounts of estradiol, an estrogen. The ...

  5. Ovulation - Wikipedia

    en.wikipedia.org/wiki/Ovulation

    The follicular phase (or proliferative phase) is the phase of the menstrual cycle during which the ovarian follicles mature. The follicular phase lasts from the beginning of menstruation to the start of ovulation. [12] [13] For ovulation to be successful, the ovum must be supported by the corona radiata and cumulus oophorous granulosa cells. [14]

  6. Estrous cycle - Wikipedia

    en.wikipedia.org/wiki/Estrous_cycle

    This phase is characterized by the activity of the corpus luteum, which produces progesterone. The signs of estrogen stimulation subside and the corpus luteum starts to form. The uterine lining begins to appear. In the absence of pregnancy, the diestrus phase (also termed pseudopregnancy) terminates with the regression of the corpus luteum. The ...

  7. Ovarian follicle activation - Wikipedia

    en.wikipedia.org/wiki/Ovarian_follicle_activation

    Ovarian follicle activation can be defined as primordial follicles in the ovary moving from a quiescent (inactive) to a growing phase. The primordial follicle in the ovary is what makes up the “pool” of follicles that will be induced to enter growth and developmental changes that change them into pre-ovulatory follicles, ready to be released during ovulation.

  8. Corpus luteum - Wikipedia

    en.wikipedia.org/wiki/Corpus_luteum

    The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation. The follicle first forms a corpus hemorrhagicum before it becomes a corpus luteum, but the term refers to the visible collection of blood, left ...

  9. Follicle-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating_hormone

    Follicle-stimulating hormone is typically measured in the early follicular phase of the menstrual cycle, typically day three to five, counted from last menstruation. At this time, the levels of estradiol (E2) and progesterone are at the lowest point of the menstrual cycle .
