Infertility can have many reasons but with modern medical innovations, the road to conceiving a child has become easy. In vitro fertilization is the process through which embryo culture takes place outside the womb of a woman. It helps to overcome complexities like infertility in both male and female. They reduce the need for surgeries to remove blockage of the fallopian tube. The process involves extraction of ovaries or eggs from the female body. Simulation lets the body produce more than one egg at a time. The eggs are then removed from the ovary using suction. Embryo culture starts after the process.
A safety reserve
It is a practice to harvest more than one egg at a time. Fusion of ovary and semen cell takes place under controlled temperature. After a span of five days from laboratory fertilization, embryos start multiplying at a normal rate. Doctors implant them in the uterine lining of a woman. While more than one cell is inserted to be on the safer side, it is a general practice to keep some samples in safe condition. These specimens aid later process of embryo transfer. The specimen is frozen so that they are intact and can be there for future use.
The varying usage
One of the purposes of freezing an embryo is for future use. There are times when a fresh transplant can fail. With the help of embryo transfer, you can get a second chance at pregnancy. It is a protocol to save and freeze embryo for future use. The cells help in a future pregnancy. You can use years after the first pregnancy. Some of the unused specimens act as donor cells. They allow you to conceive at an advanced age. The cells remain dormant and suspended for years and become active after thawing.
A comprehensive process
The implantation of the frozen embryo is a simple process and does not need any simulation or culture. The cell is thawed on the lining of the uterus so that it immediately attaches itself and springs to life. One of the processes of embryo transfer involves thawing the cell in the laboratory under controlled condition before injecting into the uterus. Once frozen, these cells remain dormant and have an infinite period. They can be thawed and put back to normal at any stage. Patients can opt for it at any given period. They do not have to go through simulation and other extensive therapy every time they want to conceive.
Preparing the body
Success in the case of frozen embryo is same as IVF. The process is same after thawing. The cell will act in the same way even years after freezing. The only therapy you require prior to embryo transfer is estrogen injections to thicken uterus lining for holding the embryo. The therapy starts two weeks before the transfer. The ideal thickness is eight millimeter after which Progesterone injection is given. The transfer takes place between four to six days of injection progesterone. In the process, there are certain medicines to suppress natural ovulation. Estrogen, on the other hand, ensures that uterine lining is thick.
