On the second day of menstruation, follicle size 15mm? On the second day after menstruation, follicular development is generally about 0.4 cm. On the second day of menstruation, the size of follicles is 65438±0.5mm, and most follicles grow at a speed of 0.2 cm. You can choose to go to the obstetrics and gynecology department of the local hospital for color Doppler ultrasound to monitor the growth and development of follicles and the ovulation of eggs. Doing this examination well is conducive to prenatal care and making active preparations for pregnancy, which can be carried out according to the size of follicles and ovulation.
It is suggested that B-ultrasound should be done on the fifth or sixth day of menstruation to know the situation of basal follicles. Basal follicles are relatively small on the fifth or sixth day of menstruation, generally about 0.5cm. Generally speaking, as long as the hormone level in the body is normal, the growth rate of follicles is about 1.5-2mm every day, the diameter of follicles can reach 1.0cm on the twelfth day of menstruation, and the follicles are on the fourteenth day of menstruation. Generally, it is about18 mm. When the follicle diameter reaches about 20mm, it will rupture and expel the egg, so it is necessary to monitor the basal follicle on the fifth or sixth day of menstruation.
Under normal circumstances, the ovarian section of a single basal follicle should not exceed 10. If it exceeds 10, polycystic ovary syndrome should be considered. Generally speaking, patients with endocrine disorders will do this. Only during ovulation will 1 ~ 2 follicles mature, most of which can mature, and can be discharged after maturity, and combine with sperm to form fertilized eggs. In this case, it is possible to get pregnant. When the egg is discharged, the thickness of the endometrium has the development of fertilized eggs, and the probability of pregnancy is high. Therefore, infertile women generally monitor follicles during ovulation to see the maturation of follicles.
Can eggs combine with eggs to have children? The combination of two eggs will definitely not give birth to a child. An embryo develops from a fertilized egg. As the name implies, a fertilized egg is a combination of sperm and egg cells. It is impossible for two eggs to combine and develop into embryos under natural conditions. Only the combination of sperm and egg can form a fertilized egg, and then the fertilized egg swims to the uterus for implantation and further develops into an embryo. And then develop into a fetus.
In fact, we all know that there is a gap between theory and experiment. Even if the theory is feasible, as long as the experiment is unsuccessful, then the theory is fallacious. And even if the experiment is successful on mice, if it has not been tested on people, then this technology can only be called theory. Of course, not everything can be experimented on people. If you can't guarantee the success of the experiment, then you can't experiment on people.
In theory, when the combination of balls becomes a reality, the position of men will become dangerous. In the past, men held up half the sky, so after this technology appeared and was widely promoted, earth-shaking changes would take place and men would become dispensable. In this era, women can do everything that men can do, sometimes even better than men.
Therefore, the technology of combining eggs with eggs to have children exists, but at present, this technology is not mature enough to be widely promoted. At present, this technology has been successful in mice, but it has not been tested in humans, so it can only be said that it is still a theory. Any theory needs to be tested on human beings before it can be patented and widely promoted.
