Knowledge sharing in the field of IVF in the United States: Description of possible experiences after embryo transfer

IVF technology is an assisted reproductive method that involves cultivating fertilized eggs in vitro and then implanting them into the mother’s uterus to achieve the goal of pregnancy. During the process of in vitro fertilization, women may experience some discomfort symptoms, which are usually caused by various factors such as changes in hormone levels, medical procedures, and drug reactions. Many women may feel anxious and worried about pregnancy failure after experiencing these uncomfortable symptoms, but in reality, there is no need to worry excessively because these symptoms are normal physiological phenomena.

After an embryo transfer, some women may experience the following symptoms:

Abdominal pain: Some women may experience mild abdominal pain after embryo transfer, sometimes similar to a needle prick, and the location and duration are not fixed. This type of abdominal pain is a common symptom after transplantation, as the implantation of embryonic tissue into the uterus may have a certain impact on the uterus. As long as the pain is mild but not severe, expectant mothers do not need to worry excessively to avoid unnecessary anxiety. But if you suddenly experience severe abdominal pain, you should seek medical attention immediately to understand the cause.

Minor bleeding: After embryo transfer, if there is bleeding or bloody discharge, attention should be paid to the bleeding situation. If the amount of bleeding is not significant, there is usually no need to worry too much. But if there is a lot of bleeding and the duration is long, it is recommended to seek medical attention to determine the cause of the bleeding. When necessary, B-ultrasound examination can be performed to determine whether there is intrauterine bleeding.

Abdominal distension and chest tightness: Abdominal distension is common after embryo transfer, and its causes may be related to factors such as progesterone injection, reduced intestinal peristalsis, and excessive rest. Within 48 hours after embryo transfer, adequate rest is necessary, but after that, moderate activity should be maintained and there is no need to stay in bed all the time. Just avoid vigorous exercise and heavy physical labor.

Constipation: Constipation after embryo transfer is a normal phenomenon. In order to protect the embryo, many expectant mothers may take excessive rest, resulting in a rich diet and lack of exercise, which can easily affect intestinal peristalsis. Combined with the influence of progesterone medication, constipation is more likely to occur. Therefore, after transplantation, attention should be paid to maintaining a balanced diet, increasing the intake of crude fiber and easily digestible foods, and engaging in moderate exercise. You can go to work normally and take a walk after meals, which not only helps with embryo implantation but also reduces the risk of blood clots. After embryo transfer, experts usually inject an appropriate amount of progesterone to assist in maintaining pregnancy.

The IVF technology in the United States has brought every expectant mother the opportunity to successfully conceive.

1. Painless egg retrieval technique increases the success rate of egg retrieval

Little Monster IVF experts in the United States will scientifically and reasonably develop personalized ovulation induction plans based on multiple indicators such as women’s age, ovarian function, basal follicle count, and hormone levels, while ensuring their physical health. The ovulation inducing drugs we use are all certified by the US Food and Drug Administration (FDA), so they are natural and have no side effects. During the drug induced ovulation period, embryologists will monitor the growth of follicles through full ultrasound, followed by a painless process of general anesthesia for egg retrieval. In this way, sufficient and high-quality eggs can be obtained.

2. By using ICSI technology, the success rate of sperm egg binding can be increased.

The test tube expert first uses gradient centrifugation to eliminate factors that are unfavorable for fertilization as much as possible, including semen, dead sperm, sperm antibodies, inflammatory cells, bacteria, and other impurities, in order to preserve sperm with normal morphology. Next, with the assistance of a high-power microscope, a sperm with abundant vitality and qualified quality is selected, and it is manually injected into the oocyte to directly complete the fertilization process, with a success rate of up to 99%.

3. Genetic screening technology (PGS/PGD) increases the probability of successful embryo implantation.

After fertilization of sperm and egg, in order to increase the chances of successful pregnancy, the Little Monster Reproductive Center in the United States usually chooses to conduct genetic testing on the embryos. IVF experts will cultivate embryos until the fifth day of development before proceeding with third-generation IVF techniques. At this stage, experts will extract 5-8 cells from the blastocyst for PGS testing to check for chromosomal duplications, deletions, translocations, and other issues, thereby reducing the risk of miscarriage. In addition, PGD technology will be used for genetic testing and diagnosis of specific segments on chromosomes. At present, the Little Monster Reproductive Center in the United States can use PGD technology to detect nearly 300 genetic diseases, which can effectively prevent the spread of various recessive family genetic diseases and improve the success rate of embryo implantation.
