LEZAMA-RUVALCABA, Jorge Luis; SALAZAR-LOPEZ ORTIZ, Carlos Gerardo; TELLEZ-VELASCO, Sergio e BAHENA-ESPINOZA, Natyeli. Results in IVF-ICSI cycles adding luteinizing hormone recombinant to follicle stimulating hormone recombinant with menotropins during ovarian stimulation in patients over 35 years-old. Ginecol. obstet. Méx. [online]. 2018, vol.86, n.6, pp.383-388. ISSN 0300-9041. https://doi.org/10.24245/gom.v86i4.2005.
OBJECTIVE
To evaluate the reproductive effects when recombinant luteinizing hormone is added and to compare two stimulation schemes by number of aspirated oocytes, mature oocytes, fertilization and implantation rates, live newborn and number of vitrified embryos.
MATERIALS AND METHODS
Longitudinal, observational and retrospective study carried out in patients of the Hisparep Reproduction Clinic of the Spanish Hospital with diagnosis of infertility, over 35 years old, who received a controlled ovarian hyperstimulation cycle with IVF-ICSI during the period 2014-2016. The statistical analysis was carried out with the Student t test for independent samples. The studies were analyzed with the IBM SPSS statistical package, version 22.
RESULTS
We analyzed 201 women with infertility, over 35 years of age. Group 1 (n = 101) of IVF-ICSI received stimulation with recombinant follicle-stimulating hormone and recombinant luteinizing hormone 2: 1 with menotropins (Pergoveris® and Merapur®) from the second day of the cycle. Group 2 (n = 100) received recombinant follicle stimulating hormone and menotropins (Gonal F® and Merapur®); in both schemes, GnRH antagonist was used from day 7 of the cycle. The average number of aspirated oocytes was 7.5 in Group 1 and 9.1 in Group 2 (p = 0.058). Mean mature oocytes were 6.2 in Group 1 vs 7.4 in Group 2 (p = 0.085). The fertilization rate in group 1 was 57 vs. 67% in Group 2 (p = 0.045). In Group 1 the implantation rate per embryo transferred fresh was 24.1 vs 10.3% in Group 2 (p = 0.40), the live newborn rate was 30% in Group 1 vs 20.6% in Group 2. The mean number of vitrified embryos in Group 1 was 1.47 vs 1.38 in Group 2.
CONCLUSIONS
The probable advantage of supplementation with recombinant follicle-stimulating hormone during ovarian stimulation in women over 35 years of age is of interest and its evaluation is required in subsequent studies.
