Why are there ovulations that have never been pregnant with children?


There have been fewer recent events, and I thought about sorting out the messages of sisters in Jin Xiu's tree hole, and then making a question compilation for the sisters. It was found that half of the 10 messages were asking "ovulation but infertility". One of the sisters said this:

I have been monitoring ovulation for 3 cycles (3 months), and the eggs are all discharged. Why are you still pregnant?

Today, let's talk about this issue.

How does an egg grow into a fertilized egg?

From the day of the menstrual cramps, your egg gradually begins its journey of growth.

As time goes by, it is stimulated by hormones in the body. One of the eggs stands out, and the essence of each absorption is longer and larger, and gradually moves to the edge of the ovary.

On the 14th day of menstruation, the fusion of hormones in the body induces rupture of the follicle, and the egg swims from the ovary to the abdominal cavity.

At this time, the egg is gently picked up at the umbrella end of the nearby fallopian tube. (The article is from Jin Xiuer Gong). Through the rhythmic movement of the cilia in the fallopian tube, the egg meets the beloved sperm, and then in the most spacious part of the fallopian tube, they are combined. Become a new individual - fertilized eggs.

Then, the fallopian tube continues to squirm, sending the fertilized egg to a more spacious and comfortable place - the uterus.

This is the entire journey of the egg from growth to maturity, discharge to fertilization.

Ovulation but the cause of infertility

Next, let's take a look at the protagonist of the egg on this journey and the scenic area it passes by.

The protagonist: egg, sperm;

Scenic area: fallopian tube, uterus;

Clearing out these, the reason for "ovulation but infertility" is explained.

The tip of the fallopian tube is far from the ovary, or there is adhesion; (Article from Jin Xiuer Gong)

Looking back on this journey, we know that after the mature egg travels to the umbrella end of the fallopian tube, it will be gently lifted by the umbrella end of the fallopian tube.

However, it is possible that the umbrella end of the fallopian tube has a certain distance from the ovary, or some adhesions, etc., and the egg cannot be found and hung back. Therefore, even if the egg grows up and is mature, it can only die alone in the abdominal cavity;

The sperm did not break through the thousands of horses and walked through the wooden bridge to meet the egg;

Even if the fallopian tube has found and hugged the egg, but the sperm did not immediately meet the egg, hiding in the abdominal cavity, but can not hide the fallopian tube, the egg died in the fallopian tube alone.

The soil in the station is barren and cannot hold the fertilized eggs.

Eggs and sperm have gone through thousands of obstacles, and finally they have met each other. Unfortunately, they have entered other places and have not reached the uterus.

The resulting embryo can only grow in the fallopian tube. The soil is poor, the food is small, the nutrition is poor, and it is impossible to grow normally. The embryos that were finally formed were once again killed.

Of course, most of the embryos can still return to the uterine cavity smoothly, but they also face various difficulties and tests when they return to the uterus. Improper size of the uterine cavity, severe adhesion of the uterine cavity, etc. may cause the embryos returning to the uterine cavity to have nowhere to live.

In addition, even if it is implanted, there may be a possibility of embryonic cessation, and it will not grow up to a certain extent. Finally, this pregnancy plan is ended with a menstrual bleeding. (Article from Jin Xiuer Gong)

Therefore, in the case of pregnancy, how to say that you still have to relax, do not come. To know a woman with regular menstruation, normal ovulation, and normal sexual life for couples, the success rate per month is only 20%.
