Intracytoplasmic Sperm Injection (ICSI / Microinjection)
In couples diagnosed with infertility (infertility), vaccination or other treatment methods are considered when not responding.
Microinjection method is applied to couples who have not enough features in terms of number, mobility and structural characteristics (severe sperm disorders), female tubes are obstructed, egg number is low or fertility problem is encountered in previous test.
Drug treatment and monitoring of egg development
The basis of the treatment is the use of hormone needles to stimulate the ovaries. The aim is to obtain a sufficient number of mature eggs in one period. For this, various treatment protocols are applied.
Egg collection and sperm collection
Collecting and maturing eggs developed as a result of treatment is done under general anesthesia. Combining these eggs with spermatozoa that are taken from the spouse and prepared by various methods is called fertilization.
With this method, fertilization is performed by injecting a single sperm cell from the father candidate into a mature egg from the mother candidate. Using this method, 50-90% of the eggs processed under normal conditions are successfully fertilized.
It means that the eggs obtained from the woman are fertilized in the laboratory with the sperm of the spouse outside of their own body. Embryo / embryos formed as a result of this procedure are placed into the uterus. When one of the embryos clings into the uterus, a normal pregnancy begins and a healthy child can be found.
The process of placing the embryos formed as a result of fertilization of the eggs into the uterus is called embryo transfer. After the embryo transfer, embryos are expected to clutch into the uterus and form a pregnancy.
If you have good quality embryos after transfer, they can be stored for later use. In this storage process, your good quality embryos are treated with special protective media and then stored at -196 ° C for future use in cold.
When do we freeze the embryo?
- If you have good quality embryonic transfer after transfer
- If endometrial thickness is not sufficient for embryo transfer
- If endometrial polyp is detected
- If you bleed the embryo transfer time
- When ovarian hyperstimulation syndrome occurs in patients with polycystic ovary syndrome
The embryos of the collected oocytes can then be frozen for transfer. Thus, the possibility of re-pregnancy can be given without the need for expensive and demanding procedures such as stimulation of the ovaries and the collection of eggs. Frozen embryos have a second chance to try for a patient who is not pregnant or pregnant.
What is the vitality rate when frozen embryos are dissolved?
The quality of frozen embryos largely determines survival rates after thawing. This ratio is about 70-80%.
