Each cycle occurs in phases based on events either in the ovary (ovarian cycle) or in the uterus (uterine cycle). The ovarian cycle consists of the follicular phase, ovulation, and the luteal phase; the uterine cycle consists of the menstrual, proliferative and secretory phases. Day one of the menstrual cycle is the first day of the period ...
The increase in estrogen and progesterone also lead to increased basal body temperature during the luteal phase. [3] The LH surge that occurs during ovulation triggers the release of the oocyte and its cumulus oophorus from the ovary and into the fallopian tube and triggers the oocyte to divide and enter metaphase of meiosis II (46 or 2n ...
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]
Ovulation is an important part of the menstrual cycle in female vertebrates where the egg cells are released from the ovaries as part of the ovarian cycle. In female humans ovulation typically occurs near the midpoint in the menstrual cycle and after the follicular phase. Ovulation is stimulated by an increase in luteinizing hormone (LH).
Menopause typically occurs at some point between 47 and 54 years of age. [8] According to various data, more than 95% of women have their last period between the ages of 44–56 (median 49–50). 2% of women under the age of 40, 5% between the ages of 40–45 and the same number between the ages of 55–58 have their last bleeding.

The higher levels of estrogen present during the pre-ovulatory (follicular) phase of the menstrual cycle lower BBTs. The higher levels of progesterone released by the corpus luteum after ovulation raise BBTs. [3] After ovulation, the temperature will be raised by at least 0.2 °C (0.4 °F), for at least 72 hours, compared to the previous six ...
The One Food OB/GYNs Are Begging People to Eat Less of Post-Menopause Several foods can make post-menopausal symptoms worse, but the biggest culprit for Dr. Javaid is alcohol.
If conception does not occur, decreasing excretion of progesterone will allow the hypothalamus to restart secretion of GnRH. These hormone levels also control the uterine (menstrual) cycle causing the proliferation phase in preparation for ovulation, the secretory phase after ovulation, and menstruation when conception does not occur.
