The presentations of José López Gálvez M.D. and Saúl Vital, M.D. revolved around fertility preservation in a forum attended by international specialists.
José López Gálvez, M.D. and Saúl Vital, M.D. responsible of the Reproduction Unit Ciudad de México, participated in the First International Course of Dialogues on Reproduction, organized by the Mexican Association of Reproductive Medicine and the Collegium of Gynecology and Obstetrics of Tijuana, held on August 18 and 19, with specialists from different cities of the country, as well as guests from Spain and the United States.
Fertility preservation was one of the main topics in the agenda, because social changes anticipate that this will be a much-needed procedure in the future considering the progressive maternity delay. The specialists of the Reproduction Center Mexico City stated that “this procedure provides benefits to women at high risk of suffering of fertility deterioration derived from their ovule quality loss for various causes, such as autoimmune diseases, endometriosis, early menopause, ovarian surgery, among others, or after radiotherapy and chemotherapy treatments in child-bearing age.”
The gynecologists explained that data indicates that at present the cancer cure rate in young patients under 35 years of age is around 80 %. Therefore, the reproductive specialists look for solutions in this field to preserve their fertility and protect the gametes from the aggressive cancer treatments.
The experts stressed the need to create awareness among physicians and scientific units of these circumstances, “because while there are may courses in this field, in practice the fertility preservation treatments are not performed systematically and following protocols.”
Preventive cryopreservation consists of the freezing and storage of ovules and semen with reproductive purposes. It consists of an ultrafast freezing process, with high cooling rates to avoid ice crystal formation, and thus prevent ovule damages or lesions.” The frozen oocytes are preserved until the time required, and when the woman intends to get pregnant, they are fertilized through intracytoplasmic sperm injection (ICSI). The embryos obtained are cultured according to the conventional techniques, following the same procedure as in vitro fertilization,” as was explained by the gynecologists.
