Older women who fail to conceive often opt for in vitro fertilization on the advice of their doctors. The process of in vitro fertilization is believed to be unfamiliar to many people. Let's take a look together.
Both husband and wife should first retrieve eggs and sperm from the egg and sperm retrieval rooms using equipment, and then put them into test tubes. They should be transported to the laboratory through a miniature disinfection window for cleaning, and artificial insemination should be performed on a glass dish, rather than in a test tube as commonly understood.
Laboratories usually cultivate around 10 embryos for couples undergoing in vitro fertilization, but not all of them can be implanted into expectant mothers, as too many can be dangerous. Usually, embryo transfer involves transferring 2 to 3 embryos based on the patient's age, previous pregnancy status, and embryo quality.
The remaining embryos are stored in a liquid nitrogen tank at -196 ℃. The experimenters will select excellent sperm and eggs under a microscope and place them in a culture incubator for cultivation. After 18 hours, the sperm and eggs will freely combine.
The incubator, which is equivalent to a female uterus, maintains a temperature of 37 ℃, and regulates humidity, carbon dioxide, and oxygen concentration according to relevant human body indices. Open the incubator and place several transparent glass dishes on each partition. These incubators are like artificial wombs, storing sperm and eggs inside.
The most critical process in the in vitro fertilization stage is that if the sperm's own strength is not enough in the culture vessel, the doctor will assist the sperm and send it into the egg, making the egg a fertilized egg.
Embryos survive in culture vessels for 3 to 5 days, then are transferred to the mother's uterus, and continue with natural pregnancy until normal delivery. If the patient is under 35 years old and undergoing IVF surgery for the first time, a maximum of 2 implants can be implanted. Over the age of 35, a maximum of 3 embryos can be placed, and any excess embryos will be frozen.
The woman walked out of the operating room after the surgery. If all three implanted embryos develop well, according to relevant requirements, technology must also be used to reduce the chances of triplets or twins.
The process of conceiving in vitro fertilization is also full of hardships, but all the hardships are worth it. Looking forward to the arrival of the little angel.
