Process of PGD IVF
Test tube baby is a modern technology, and the most commonly used one is PGD (Preimplantation Genetic Diagnosis). PGD improves the health of infants by detecting embryos related to the treatment of genetic genes other than certain congenital diseases. The flow of PGD IVF will be described in detail below.
1. Consultation and evaluation
Before carrying out PGD test tube baby, both husband and wife need to go to the formal hospital for consultation and evaluation. The doctor will know the birth history, family medical history and other relevant information of the couple in detail. At the same time, doctors will also explain the principle, success rate, risk and cost of PGD technology to help couples make decisions.
Once the couple decides to carry out PGD test tube baby, the next step is physical examination. The doctor will conduct a comprehensive physical examination for both the husband and wife to check their health and ensure that they are suitable for IVF.
After the assessment, the husband and wife will work with the doctor to develop a treatment plan for PGD IVF, including specific arrangements for egg retrieval cycle.
2. Ovulation promotion and egg retrieval
During the treatment of PGD test tube infants, ovulation induction therapy is the first step. The doctor will develop a personalized ovulation promotion program according to the specific conditions of the husband and wife, and stimulate the development of female eggs through hormone drugs.
When the egg is mature, the doctor will take the egg. Egg retrieval is usually performed 36 hours before the ovulation of the woman. The mature eggs are extracted from the woman's ovary by puncture technology. The egg retrieval operation needs to be carried out under sterile conditions, generally combined with local anesthesia or intravenous anesthesia.
After the egg retrieval operation, the eggs will be sent to the laboratory for PGD testing.
3. Embryo culture and PGD
In the laboratory, the eggs taken out will be fertilized with sperm from the man to form an embryo. Then, the embryo will be cultured for several days until it reaches the appropriate development stage, usually 5-6 days.
At the same time of embryo culture, the doctor will conduct PGD test on the embryo. PGD detection can detect whether embryos carry abnormal genes related to specific genetic diseases through gene analysis technology. Specific detection items include chromosome number abnormality, monogenic disease, blood disease, etc.
PGD testing can help doctors screen healthy embryos and reduce the risk of birth of babies with genetic diseases.
4. Embryo transfer and pregnancy
After PGD test, doctors will select healthy embryos for embryo transfer. The time of embryo transfer is usually 5 to 7 days after PGD detection.
Generally, embryo transfer does not require anesthesia. Doctors will put multiple embryos into the woman's uterus through a catheter. Then, both husband and wife need to wait several days for a pregnancy test.
Once pregnant, both the husband and the wife need to conduct regular pregnancy inspection, and follow the doctor's recommendations for relevant treatment and drug use. Generally speaking, after a successful pregnancy, both husband and wife can successfully welcome the birth of the baby.
summary
The process of PGD IVF includes consultation and evaluation, ovulation induction and oocyte retrieval, embryo culture and PGD, as well as embryo transfer and pregnancy. PGD technology improves the health of infants by screening healthy embryos, which brings hope to couples with genetic diseases.
