With the liberalization of the second child policy, more and more women are joining the ranks of senior pregnancy – IVF. However, senior pregnancy is different from the age-appropriate pregnancy, because of the aging, the ovarian reserve function decreases, the quality of oocytes changes, the chance of chromosomal abnormalities increases, and the embryo implantation rate decreases, which leads to a much lower success rate of IVF. This time, we are going to popularize the strategy of preparing for pregnancy at an older age and wish you good luck to become a happy parent. What is an advanced pregnancy? What is your success rate of IVF? As seen from the above chart, the most fertile age for women is from 25 to 29 years old, and fertility starts to decline gradually after 30 years old, and declines rapidly after 35 years old. What are the pregnancy preparation strategies for older women? 1. Protect [the seed] Try to avoid the damage of multiple abortions. If we compare the egg to a seed, then the uterus is like the soil that nurtures life. Whether it is a medical or surgical abortion, it inevitably affects the soil that is the lining of the uterus. If performed repeatedly, it may cause problems such as infertile land such as thin endometrium, which prevents conception. Moreover, surgical abortion may also cause pelvic inflammation, tubal adhesions, endometriosis, etc., which may also affect fertility. In addition, a significant percentage of older women have experienced a physiological decline in ovarian reserve function and egg quality. The success rate of IVF can be improved to some extent by taking oral Toluen. 2. Manage your weight Before pregnancy, keeping your weight within the standard range can reduce the risk of diabetes and hypertension during pregnancy, and is also more beneficial to the health of the fetus. For typical PCOS patients, weight management is especially important. By controlling BMI within the normal range, it can help improve the disordered menstrual cycle, regulate the endocrine balance of the body and increase the natural pregnancy rate. 3, maintain a healthy lifestyle and good mood (1) do not smoke, do not drink, do not stay up late, less exposure to electronic radiation, regular rest and relaxation. (2) In terms of diet, pay more attention to fresh vegetables, fruits, eggs, milk, lean meat and other foods rich in high quality protein every day, but control the intake of salt. In addition, some medications such as oral amino acid capsules can also help to replenish the body and improve the quality of eggs. Of course, these aspects also apply to men, as improving the quality of male sperm is also essential for the formation of quality embryos. (3) Sleep is also important, as getting enough sleep is one of the most crucial factors in improving the immunity of the body. (4) Release stress. Negative emotions can affect conception and delivery. Let nature take its course and relax. (4) Take oral folic acid 3 months in advance A large amount of evidence shows that a reasonable dose of folic acid supplementation before pregnancy can reduce the incidence of fetal neural tube abnormalities. Daily diet is often not enough to ensure pregnancy, so it is recommended that women preparing for pregnancy should start taking folic acid tablets 3 months before conception, or take oral Aleve, which is a multivitamin tablet. 5. Genetic Screening (PGD/PDS) Because of the decline in body functions due to ageing, older women often have aging eggs, aneuploidy and other structural abnormalities in embryos, etc. PGD/PDS can screen for various single gene defects, as well as check for chromosome deletions and normal chromosome morphology.
