The role of chorionic villus in transplanting frozen embryos

In vitro fertilization technology has come into everyone's sight. From the advent of in vitro fertilization technology to the present, many people have become parents with the help of this technology, so this technology has gained the trust of many people and can be seen in some large hospitals. After undergoing in vitro fertilization, doctors recommend that women take chorionic vomica. Why is that?

This is to prepare for embryo implantation. The hcg injection after test tube transplantation is to increase the body's progesterone level, assist the fertilized egg to implant and increase hcg. Its key function is to stimulate progesterone, which is beneficial to the continuous metabolism of estrogen and corpus luteum copper, and is beneficial to the implantation of blastocyst embryos.

Chorionic gonadotropin is a glycoprotein growth hormone produced by the embryo and extracted from the urine of pregnant women. It can stimulate the activity of sex hormones, promote egg perfection and ovulation in women, and promote the function of seminiferous tubules and the activity of interstitial cells in the testes in men to increase the production of androgen, promote testicular descent and promote sperm formation. It is common in sexual dysfunction, habitual abortion, severe abnormal uterine bleeding, amenorrhea, infertility, cryptorchidism, etc., but it is ineffective for cryptorchidism caused by anatomical changes in the human body.

Chorionic gonadotropin and luteinizing hormone (LH) have the same α subunit structure. It has similar biological activity and immune specificity to LH. When used to promote egg maturation, large doses of injection are required to simulate the LH peak before ovulation, thereby accelerating egg maturation and inducing ovulation.
