ICSI (intracytoplasmic sperm injection) Brazil

Through special microscopes and micromanipulators, a single sperm is injected into an egg through a needle about seven times thinner than a hair.

In micromanipulation, the process of ovulation stimulation and egg retrieval is done in a manner similar to that of in vitro fertilization.

This technique is used not only for those men with low sperm number or quality, but also for those who do not have any sperm in the semen. In these cases, the spermatozoon is recovered from the epididymis (a canal soon after the exit of the testicle) or even from the testicle through a biopsy.
In order to improve pregnancy rates, the Center for Human Reproduction Prof. Franco Junior uses only morphologically selected spermatozoa. A microscope equipped with a high-resolution lens system allows amplification of the sperm image by 15,250 times, making it possible to accurately assess the characteristics of the nucleus, the intermediate part and the tail of these cells. Thus, the technique selects spermatozoa with perfect morphology, leading to an increase in pregnancy rates and a decrease in the number of abortions. Super-ICSI has already addressed difficult cases of infertility, where patients had gone through several frustrated attempts at IVF / ICSI.
