ZYGOS offers less invasive techniques in the treatment of male infertility.
Stimulation of spermatogenesis
Stimulation of spermatogenesis by gonadotropins. In men, this hormone is an essential stimulant for the synthesis and maturation of sperm. The pulsatile GnRH is indicated for cases of Hypogonadotropic Hypogonadism also called Sexual Infantilisms; that occur when there is no secretion of GnRH, LH and FSH. Often it causes structural abnormalities in the central nervous system, the hypothalamus, which affect the synthesis or normal GnRH secretion.
Testicular biopsy (TESE)
It is a surgical technique in which samples of testicular tissue of the male are obtained. Its applications in assisted reproduction can be: as a complementary test for the diagnosis within the previous study for male and to obtain sperm needed for carrying out assisted reproduction treatment, in case of a severe male factor or obstructive azoospermia. Afterwards, freezing tissue guaranteeing not to have to repeat the surgery if it is necessary to make more than one cycle of fertilization is often.
It is a technique for isolating motile sperm whereby the seminal plasma or any potentially infectious cell are eliminated, obtaining only useful motile sperm for assisted reproduction treatments. It applies in cases of seropositive men: Hepatitis C, HIV.
Testicular aspiration (TESA)
It is a minimally invasive technique of fine-needle aspiration for obtaining sperm. Testicular aspiration, TESA, is the most effective in detecting active foci of spermatogenesis in the testes because it allows to access to areas of deeper tissue.
Microsurgical epididymal aspiration (MESA)
Technique performed to extract sperm directly from the epididymis. It is a standard procedure in cases of azoospermia.
Aspiration epididymis (PESA)
This technique involves removing sperm directly from the epididymis, area adjacent to the testes where they are stored and acquire a great mobility before being released in the ejaculate.
It is the technique recommended in patients about to undergo radiation or chemotherapy treatments for cancer or autoimmune process in order to preserve the male fertility after the treatment. Psychologically it usually helps that allows a positive attitude toward healing and previous vasectomy.
