Journal ArticleDOI
Embryo incubation and selection in a time-lapse monitoring system improves pregnancy outcome compared with a standard incubator: a retrospective cohort study
Marcos Meseguer,I. Rubio,María del Carmen de la Orden de la Cruz,N. Basile,Julián Marcos,Antonio Requena +5 more
TL;DR: Analysis of retrospective data indicated that culturing and selecting embryos by TMS significantly improved the relative probability of clinical pregnancy and was attributed to a combination of stable culture conditions and the use of morphokinetic parameters for embryo selection.
Journal ArticleDOI
The aromatase inhibitor letrozole increases the concentration of intraovarian androgens and improves in vitro fertilization outcome in low responder patients: a pilot study.
Juan A. Garcia-Velasco,L. Moreno,Alberto Pacheco,A. Guillen,Luis Duque,Antonio Requena,Antonio Pellicer +6 more
TL;DR: Adding 2.5 mg of letrozole to a high-dose FSH/hMG antagonist protocol increases intraovarian androstenedione and T concentration and improves IVF cycle outcome in poor responder patients.
Journal ArticleDOI
Adenomyosis in infertile women: prevalence and the role of 3D ultrasound as a marker of severity of the disease
TL;DR: The results indicate that adenomyosis is a clinical condition with a high prevalence that may affect the reproductive results and the described severity criteria may help future validating studies for better counseling of infertile couples.
Journal ArticleDOI
High doses of gonadotrophins combined with stop versus non-stop protocol of GnRH analogue administration in low responder IVF patients: a prospective, randomized, controlled trial
Juan A. Garcia-Velasco,Verónica Isaza,Antonio Requena,Fco.Javier Martínez-Salazar,A. Landazabal,José Remohí,Antonio Pellicer,Carlos Simón +7 more
TL;DR: The early cessation of GnRHa combined with high doses of gonadotrophins permitted the retrieval of a significantly higher number of oocytes in the study group (stop protocol), and both protocols resulted in a similar cancellation rate.
Journal ArticleDOI
Maturation in vitro of human oocytes from unstimulated cycles: selection of the optimal day for ovum retrieval based on follicular size
Ana Cobo,Antonio Requena,Fernando Neuspiller,M. Aragonés,Amparo Mercader,José Navarro,Carlos Simón,José Remohí,Antonio Pellicer +8 more
TL;DR: The data suggest the importance of retrieving immature oocytes before follicular selection, and define the conditions for the first stage in the use of immature oocyte retrieval, before further stages must be defined before this technique can be used clinically.
