What is ovulation and the signs of egg maturation and release

Every month, a woman's body grows a follicle with an egg ready to receive a sperm and turn into a new life. How does ovulation work?

When ovulation happens

Usually, ovulation (the breaking of the follicle wall and the release of the egg) happens when the follicle reaches a size of 18–22 mm. Read more information about the menstrual cycle.

So, it had been growing and growing and finally grew up. The dominant follicle with the egg inside.

Ovulation disorders

Sometimes the ovary does not receive a command from the brain or simply does not hear it – has not learned or, on the contrary, has forgotten how. In this case, the follicle continues to grow, turning into a persistent follicle. Then it can reach a size of more than 35 mm and turn into a corpus luteum cyst, which resolves with the start of menstruation. It mostly resolves.

There are situations when the dominant follicle changes its intention to grow and develop. Just halfway to ovulation, it stops and goes into atresia, meaning it decreases in size again.

It’s just like in life. There is always a choice of development path!

Ovulation signs

Sign 1

Due to estrogen, which is actively produced by the growing follicle, a viscous transparent mucus is formed in the cervical canal (see the video below). Abundant mucus discharge is a signal to the body that ovulation will be soon, within 48 hours. The task of this abundant cervical mucus is to help sperm overcome the cervical canal and enter the cavity as soon as possible.

Sign 2

Mom, why, if I’m supposed to be as attractive as possible these days, am I so “pimpled”?

The rupture of the main follicle occurs due to a sharp jump in luteinizing hormone. This is the cause of the acne on the sides of the chin these days.

Sign 3

“Fertile days” is what doctors call 48 hours from the moment of ovulation and 24 hours before it. This is the time that is most favorable for conception. And given the instincts, libido also increases significantly in most women during these days, but there are nuances. Read more in my article about the different libidos of partners.

Sign 4

Ovulatory pain. Some women experience pain of varying intensity during the rupture of the dominant follicle. Slight sensitivity is a variant of the norm. Pain is a reason to see a gynecologist.

And if you are worried about chronic discomfort in the intimate area, then the article “Why is my vagina dry?” – will be in handy.
