IVF and the Physiological Process of Natural Pregnancy
IVF is a child that is bred through assisted reproductive technology in the process of in vitro fertilization and embryo development. In contrast, natural pregnancy is the combination of sperm and eggs through sexual intercourse, and the embryo develops into a baby in the female uterus. The following is a detailed comparison between IVF and natural pregnancy from four aspects: physiological process, success rate, medical means and psychological pressure.
1. Physiological process
The process of IVF consists of three main steps: ovulation, oocyte retrieval and in vitro fertilization. First, women are ovulated through drug therapy to produce multiple eggs. Then, an egg taking operation is carried out in the hospital, and the egg and sperm are combined in the laboratory to form a fertilized egg. Finally, after the fertilized egg is cultivated into an embryo, the embryo is transferred back to the female uterus to develop into a baby.
Natural pregnancy relies on sexual intercourse to combine sperm and eggs, and the embryo gradually develops into a baby through the development process in the womb.
2. Success rate
The success rate of IVF technology is usually affected by many factors, including age, health status, doctor's skill level, etc. According to the statistics of a famous hospital in China, the success rate of IVF is usually between 30% and 50%. This means that it takes several attempts to conceive successfully.
The success rate of natural pregnancy depends on the couple's physical condition, ovulation cycle and sexual life frequency. Generally, there is a 20% chance of pregnancy every month, but this number will decline with the increase of age.
3. Medical means
IVF needs the assistance of medical institutions to carry out assisted reproductive technology, such as hormone therapy, egg retrieval surgery and embryo transfer. This involves the application of doctors' professional skills and equipment, which needs to be carried out in hospitals.
Natural pregnancy does not need any medical means, but only sexual life between husband and wife, nutrition and healthy diet to help improve the chance of pregnancy.
4. Psychological pressure
The process of IVF may cause psychological pressure on both spouses. Due to the high number of attempts and long cycle, it may lead to emotional problems such as anxiety, disappointment and mood fluctuations. In addition, drug treatment during IVF may bring some side effects, which may bring physical discomfort to patients and further increase psychological pressure.
Natural pregnancy can reduce psychological pressure, because couples can prepare and conceive in a more natural and relaxed way, reducing the psychological burden brought by the medical process.
To sum up, there are obvious differences between IVF and natural pregnancy in terms of physiological process, success rate, medical means and psychological pressure. IVF needs the assistance of doctors and medical equipment, has a certain success rate, and may bring greater psychological pressure. While natural pregnancy depends on the physical conditions and sexual life of both spouses. The success rate is affected by many factors, but it is usually high and can reduce psychological pressure. Each husband and wife can choose their own reproductive mode according to their own conditions.
