Risk and complications of IVF cycle progression
IVF is an assisted reproductive technology, which helps infertile patients realize their dreams of pregnancy and fertility through in vitro fertilization (IVF) or embryo transfer (ET). However, there are certain risks and complications during IVF cycle, which will be described in detail from several aspects below.
1. Risk of the elderly puerpera
Age is an important factor in IVF cycle. With the increase of age, women's ovarian function decreases, and the quality and quantity of eggs gradually decrease, leading to a lower success rate. Both the probability of successful pregnancy and the probability of embryo implantation will be affected. In addition, older women also face higher risk of pregnancy complications, such as abortion, fetal termination, gestational diabetes, etc.
For the elderly puerpera, a comprehensive physical examination, including cardiopulmonary function, blood indicators, gynecological examination, etc., is required before the IVF cycle to assess the risk of suitable acceptance of IVF.
2. Risk of multiple pregnancy
In the cycle of IVF, in order to improve the probability of successful pregnancy, multiple embryos are often transferred into the uterus. However, multiple pregnancy will increase the risk of pregnant women and fetuses. In multiple pregnancy, the mother may have complications such as premature delivery, anemia, pregnancy induced hypertension, and the fetus may face risks such as premature delivery, stunting, and labor.
In order to reduce the risk of multiple pregnancy, the number of embryos transferred is generally limited according to the patient's age, egg quality and medical history. This can reduce the incidence of multiple pregnancy to a certain extent.
3. Ovarian Hyperstimulation Syndrome
Ovarian hyperstimulation syndrome (OHSS) is a common complication in IVF cycles. This syndrome is mainly due to the use of ovulation promoting drugs to stimulate ovarian overreaction, resulting in follicular overdevelopment and the formation of osmotic ascites. Symptoms generally include abdominal distension, abdominal pain, fatigue, nausea, vomiting, etc.
In order to prevent and reduce the occurrence of OHSS, doctors will adjust the dosage and use of ovulation promoting drugs according to the individual conditions of patients. In addition, timely detection of follicular development and control of the best time for egg retrieval are also important measures to prevent OHSS.
4. Postoperative infection
In the IVF cycle, operations such as ovarian puncture or embryo transfer are required, and these operations have a certain risk of infection. Postoperative infection may lead to fever, abdominal infection and other symptoms, and increase the probability of embryo transfer failure.
In order to reduce the risk of infection, the hospital will strictly implement aseptic operation, and give appropriate antibiotic prevention before and after the operation to improve the safety and success rate of the operation.
summary
Although IVF cycles can help infertility patients achieve their reproductive aspirations, they are also accompanied by certain risks and complications. Older women may face higher maternal risks, multiple pregnancies will increase the risks of both mothers and infants, ovarian hyperstimulation syndrome and postoperative infection are also common complications. In order to reduce the risk, patients should fully understand the relevant information before choosing IVF and treat under the guidance of doctors.
