Number of follicles on the second day of menstruation

An egg is composed of an oocyte and some oocyte somatic cells. Only when a woman reaches adulthood can she produce an oocyte, which then fuses with the male sperm to grow into a sperm-egg combination and finally grows into a baby. The number of eggs in the human body is not infinite, it will gradually decrease, so what is the normal range of egg number? How many eggs are there on the second day of menstruation?

How many eggs are there on the second day of menstruation?

The second day of the menstrual period belongs to the antral follicle phase, and the eggs are still relatively small, with a diameter of less than ten mm. The number of antral eggs is five to seven and it is normal. Too few may be due to poor ovarian reserve function, and too many may be due to polycystic ovary. To understand whether there is a normal ovulation period, it is more meaningful to continue testing. It is recommended to start testing by vaginal ultrasound from the eleventh day of the menstrual period. The normal mature follicle is 18 to 23 mm.

After menstruation, the uterine wall falls off and the estrogen level decreases. At this time, the egg begins to grow. Generally speaking, for women with regular menstruation, the growth of the egg is about 0.4 cm on the second day after menstruation, which is normal. During the development of the uterus, most of the cells grow at a normal rate of 0.2 cm.

If you want to prepare for pregnancy, you can calculate the time of ovulation based on the growth rate of the egg. Or you can start from the 12th day of the menstrual period, continue to monitor ovulation every day, use B-ultrasound to measure the size of the egg, and use this to calculate the ovulation period, which will be more accurate. Having sex during the ovulation period can greatly increase the chances of pregnancy.

On the second day of the menstrual period, the eggs tested were clinically antral eggs, with a diameter of about 2-4mm, so they were very small. Clinically, follicle monitoring is best started on the 12th day of menstruation, and the growth and development of the eggs can be understood through B-ultrasound examination. On the 12th day of the menstrual period, the diameter of the egg is clinically about 12 mm, and the normal growth rate of the egg is 1.5-2 mm per day. About 16 days into the menstrual period, when the diameter of the egg reaches about 20 mm, it will break apart and remove the oocyte. Therefore, the egg is growing and developing throughout the menstrual period, and follicle monitoring is best performed close to the ovulation period.

What is the normal range of egg count?

When a newborn is born, there are about 150,000 to 500,000 eggs in the ovaries. After an adult, only about 400 to 500 are fully developed, and the rest are atrophied. After menopause, there are basically no eggs in the ovaries. The left ovary of an adult woman has 6 to 15 eggs, and the right ovary has 3 to 9 eggs. Values ​​similar to this range are all normal, and there are not many problems if they are close to this value.
