The ovaries during ovulation: the center of women’s reproductive health
What is ovulation?
Ovulation refers to the time during a woman's menstrual cycle when her ovaries release eggs. Normally, a woman's menstrual cycle lasts 28 days, and ovulation occurs between the 14th and 19th days of the menstrual cycle. The specific time may vary depending on individual differences.
During ovulation, the ovaries begin to release eggs, which are picked up by the fallopian tubes and travel to the fallopian tubes to await fertilization. This process takes several days, so the ovulation period is also called the "egg discharge period" or "danger period."
Basic knowledge about ovaries during ovulation
1. Ovarian size and shape
The ovaries are two small reproductive organs located behind the uterus, and their size and shape vary between individuals. Generally speaking, the size of the ovary is 2.5 cm to 3.5 cm, and the shape is oval or spherical.
2. Structure and function of ovaries
There are a series of cells inside the ovary, including the ovarian cortex and ovarian medulla. The ovarian cortex is the main part of the ovary and contains many mature and immature eggs. The ovarian medulla is where the eggs are released. Cells in the ovarian medulla continue to divide and mature, forming more eggs.
3. Physiological functions of ovaries
The main functions of the ovaries are to produce eggs and provide support to the female reproductive system. During ovulation, the ovary releases a large number of eggs, which pass through the fallopian tube and enter the fallopian tube to wait for fertilization. In addition, the ovaries also secrete a variety of hormones, such as estrogen, progesterone, and testosterone, which play a vital role in women's reproductive health and reproductive function.
Physiological changes in the ovary during ovulation
1. Maturation and division of ovarian cortical cells
During ovulation, ovarian cortical cells continue to mature and divide to form more eggs. These eggs wait in the ovarian medulla for fertilization.
2. Cellular changes in the ovarian medulla
In the ovarian medulla, cells continue to divide and mature to form more eggs. During ovulation, cells in the ovarian medulla undergo a series of complex changes, such as the separation and combination of chromosomes. These changes help ensure the quality and safety of eggs.
3. Vascular and neural changes in the ovary
During ovulation, the blood vessels and nerves of the ovary change to adapt to new physiological needs. For example, the blood vessels in the ovaries become more open to accommodate a greater blood supply. In addition, the nerves in the ovaries become more sensitive to new stimulation.
Summarize
The ovaries are an important part of the female reproductive system and the center of female reproductive health. During the ovulation period, the ovaries undergo a series of complex physiological changes that play a vital role in women's reproductive health and function. Understanding these physiological changes can help better protect women’s reproductive health.
