In IVF, which is the classical IVF method, sperm and eggs are brought side by side, and the sperm are expected to fertilize the egg. In the microinjection method, also known as intracytoplasmic sperm injection (ICSI), the sperm cell is taken into a glass needle and injected directly into the egg, ensuring fertilization. Microinjection applications are performed when the sperm count is insufficient, the motility is below average, and the cells cannot fertilize the egg.
The most important advantage of the microinjection method is that men with problems in sperm motility and number can also benefit from the in vitro fertilization method.
To Whom is it Applied?
Microinjection, which is different from the IVF method only in the fertilization process, is applied in cases where the sperm count and quality are low, as well as in the presence of sperm antibodies that prevent fertilization, fertilization by the classical method, and in cases where there is a problem in fertilization despite the absence of a certain sperm problem.
What is drug-free in in vitro fertilization (IVF) treatment?
In the classical IVF treatment, hormone-containing needle therapy is applied to obtain more eggs and embryos. However, some women’s ovarian capacity is insufficient to produce many eggs. In cases where the number of ovaries is low, and the chance of success with hormone injections is low, a non-drug treatment method in which women’s menstrual cycles are followed is preferred. In this method, which focuses on egg quality instead of egg number, women are either not given any medication or very low doses of hormones. The continuation of the procedures is similar to classical IVF. Following the natural spawning process, the eggs that come to the appropriate size are collected by needle. After fertilization, the embryo is placed in the uterus.
The advantages of drug-free IVF treatment, which is preferred in women with insufficient egg reserves, are as follows:
- Shorter duration of treatment compared to IVF, which is the classical IVF treatment,
- Low or no side effects because no medication is used,
- Less clinical and ultrasound controls,
- The risk of developing complications is very low,
- Injection applications are either very few or not at all,
- Lower cost.
