Impact of embryo biopsy technique on the prevalence of mosaicism
An observational study led by the embryologist Lluc Coll analysed whether the prevalence of mosaic embryos in ART cycles with preimplantation genetic testing for aneuploidy (PGT-A) is associated with the trophectoderm biopsy technique used or with the time elapsed until the tubing of the sample.
Is gestational diabetes more common in ART patients?
A retrospective study led by Dr Gemma Sesmilo analysed whether women who use assisted reproductive technology have a higher incidence of gestational diabetes than those who become pregnant spontaneously. The research also assessed whether…

Initiating ovarian stimulation at the luteal or follicular phase does not influence reproductive outcomes
Dexeus Mujer has conducted a prospective study to evaluate whether starting ovarian stimulation in the luteal phase (LS) or the follicular phase (FS) of the menstrual cycle offers better reproductive outcomes. The study was conducted in 44 oocyte donors who underwent…
The first analysis of oocyte transcriptomes, awarded at the 33rd SEF National Congress
A study led by Dr Francisca Martínez of the Reproductive Medicine Unit of Dexeus Mujer analysed oocyte transcriptomes after two different LH suppression protocols in the same patient: with a GnRH antagonist (ANT) and with progesterone.
Monitoring of egg donation cycles by nurses improves donor satisfaction
The nursing staff of the Reproductive Medicine Unit at Dexeus Mujer has carried out a retrospective observational study to see whether incorporating folliculometry into their routine during egg donation monitoring cycles can contribute to improving donor satisfaction without affecting the outcome of the treatment.
In ART, the sex of an embryo has no influence on implantation or whether the pregnancy is carried to term
A group of researchers at Dexeus Mujer, led by biologist Beatriz Carrasco, carried out a retrospective study to determine the sex ratio in the blastocyst stage of human embryos generated by ICSI, in transferred and implanted euploid blastocysts, and, finally, in babies at birth.
Fertility experts at Dexeus Mujer assess the indication for ICSI in assisted reproduction and debunk myths
Although ICSI has meant a significant advance in the field of reproductive medicine in patients with male infertility problems, there is a certain disparity of opinions in the medical world about its use in other cases of infertility.
Embryo transfer at the blastocyst stage improves pregnancy and live-birth rates in egg donation treatments
The study, led by the biologist Dr Elisabet Clua, head of the Oocyte and Embryo Donation Programme at Dexeus Mujer, was carried out at this centre between April 2017 and August 2018. The sample of women under study were recipients…
