Answer:
Between days 5 and 13 of a woman's menstrual cycle, an unfertilized egg in ovary prepares its development and maturation within the follicle, while the lining of the uterus -the endometrium- progressively enlarges.
Explanation:
Under normal conditions, a woman's menstrual cycle lasts 28 to 30 days, during which time both hormonal and physiological changes occur as part of the reproductive process.
Menstruation occurs as a result of the shedding of the endometrium, which had previously developed to facilitate the implantation of a possible pregnancy. This phase usually lasts five days and is characterized by genital bleeding.
From the fifth to the 13th day, a woman's reproductive system undergoes changes in preparation for possible fertilization and pregnancy:
- <em>The unfertilized egg</em><em> is found inside the ovarian follicle, maturing before its imminent release, under the influence of follicle-stimulating hormone (FSH). The maturation of a few follicles occurs simultaneously, but only one will reach the necessary maturity to allow the release of the egg.
</em>
- <em>The lining of the uterus</em><em>, called the endometrium, receives signals from the hormone estradiol -produced by the mature ovarian follicle- and induces proliferation and thickening of the endometrium.</em>
Approximately on the 15th day of the menstrual cycle, the egg is released and it is the time when it can be fertilized by a sperm to produce the zygote, which will start a pregnancy in women.
