Steps of pulling test tube baby
Labrador test tube baby is a kind of assisted reproductive technology, which can help couples who cannot conceive in a natural way to realize their dreams of childbirth. After years of development and improvement, this technology has been widely used worldwide. The following will elaborate the steps of pulling IVF from four aspects.
Women's preparation
First, women need to undergo a series of physical examinations to ensure that their physical condition is suitable for IVF. This includes gynecological examination, medical history investigation and some special laboratory items. After that, women need to inject growth hormone to promote the development of eggs. After the follicles develop to the proper size, the doctor will inject the women with chorionic gonadotropin (HCG) for ovulation. Then, the doctor will arrange the operation according to the ovulation time. Egg retrieval is usually performed 36 hours before the release of eggs, and the eggs are taken out through a vaginal or abdominal incision.
Before ovum retrieval, women also need to prepare their endometrium. This includes taking estrogen drugs to promote endometrial thickening. When the endometrium reaches the proper state, doctors will carry out embryo transfer.
Throughout the process, women need to adhere to regular medical treatment, follow the guidance of doctors and cooperate with various examinations and treatments.
Male preparation
The preparation of men in the process of pulling IVF is mainly to provide sperm samples. Doctors can obtain sperm by natural or artificial ejaculation. Before ejaculation, men need to avoid overwork and sexual activity to ensure sperm quality. Ejaculation is usually carried out in the privacy of the hospital.
After sperm samples are collected, they will be processed and screened to select high-quality sperm for combination with eggs.
Embryo culture and selection
After the sperm is combined with the egg, the embryo begins to be cultured in the laboratory. This process usually takes five to six days. During the culture process, doctors will observe and evaluate the development of the embryo.
According to the condition and personal needs, doctors may choose to carry out embryonic genetic diagnosis (PGD). PGD can help screen out normal embryos and reduce the risk of chromosomal abnormalities and genetic diseases. After selecting healthy embryos, doctors will transfer them.
Embryo transfer and follow-up monitoring
Embryo transfer is the last step in the IVF process. Doctors will use catheters to transfer the screened embryos into a woman's uterus. After transplantation, women need to rest for a period of time to avoid strenuous activities and physical discomfort.
After transplantation, doctors will conduct regular observation and testing to ensure the safe implantation of embryos and the smooth progress of pregnancy. If the pregnancy is successful, women need to continue to receive monitoring and care during pregnancy.
In short, pulling IVF is a complex and rigorous process, which requires the cooperation of women and men and the professional guidance of doctors. From women's preparation, men's preparation, embryo culture and selection, to embryo transfer and follow-up monitoring, every step is very important. Only through comprehensive preparation and strict operation can a healthy baby be born.
The procedure of pulling IVF is very clear, and it has been proved by practice that it can help many couples to successfully realize their dreams of childbearing.
