Técnica de doble disparo (doubble trigger) en pacientes normorrespondedoras con bajo porcentaje de ovocitos maduros

OBJECTIVE: To evaluate the effect of double trigger in patients with a previous cycle with less than 65% of mature oocytes compared to the captured oocytes, in a normor-responding population with induction of ovulation with recombinant or urinary hCG. MATERIALS AND METHODS: A prospective cohort study, conducted in patients diagnosed with infertility, treated with in vitro fertilization, evaluated at the Mexican Fertility Center (Hospital Angeles Lomas) between 2017 and 2019. The treatment was carried out in the same patient, in whose previous conventional cycle with antagonist scheme and induction of ovulation with hCG had suboptimal ovarian response and oocyte capture with less than 65% in M2 phase (Group 1). Subsequently, a second cycle was performed with the same scheme of gonadotropins and induction of ovula- tion with double shot: 1 mg triptorelin acetate + 5000 IU of urinary hCG 40 and 34 hours prior to capture (Group 2 or double trigger). Percentage and quantity of oocytes captured in M2 phase were evaluated. CONCLUSIONS: The prospective studies are required to elucidate the aforementioned recommendation of the “double
