Intracytoplasmic Sperm Injection (ICSI)
This procedure is performed when sperm is unable to penetrate the membrane that surrounds the egg. Using a very fine needle, the microinjection technique provides the means to introduce a single sperm cell into the cytoplasm of the egg. The course of treatment then follows that of IVF without microinjection.
Today, this technique gives excellent results and enables couples, where the man is deemed infertile, to one day hopefully conceive a child.
Testicular Sperm Aspiration (TESE)
The procedure is only performed when dealing with In Vitro Fertilization with ICSI (microinjection of sperm). It consists in taking sperm directly from the testicles and is performed under local anesthetic. This technique is used when there is a complete absence of sperm in the ejaculate or in the epididymis while the testicles continue to produce sperm. Sperm is retrieved and treated, the healthiest sperm is then used for IVF with microinjection.
In Vitro Fertilization Using Donor Sperm
In the case where the spouse experiences severe infertility, it is possible to perform In Vitro Fertilization with donor sperm. The process is identical to that of conventional IVF.
