Azoospermia is one of the causes of male sterility. In order to be able to retrieve spermatozoa in men with this condition, the man has to undergo techniques involving sperm aspiration from the epididymis or testicles, or a testicular biopsy. Although these techniques can be performed at any time and the samples can be cryopreserved for use in the future, with our patients we generally aim to synchronise the procedure with oocyte retrieval. When we do so, the procedure can be performed the day before or the same day as the ovarian puncture that is used to retrieve oocytes from the female partner. Researchers at Instituto Bernabeu carried out a study to find out which of the two days chosen for testicular spermatozoa retrieval gave the best clinical results. The research work was presented to the 1st National Congress of the Spanish Society of Gynaecology and Obstetrics (SEISEGO) that was held within the framework of the Spanish Society of Gynaecology and Obstetrics Congress (SEGO).
A team of gynaecologists, embryologists, molecular biologists and biologists at Instituto Bernabeu has carried out research to determine if there is an increased number of monozygotic twin pregnancies following transfer when an embryo biopsy during the blastocyst stage (day 5 or 6 of development) has been performed. The twins come from a single ovum or single spermatozoon and they have the same genetic make-up. Pregnancies of this kind are also linked to various perinatal complications.
Instituto Bernabeu has presented research work analysing the clinical results obtained in an oocyte donor programme following random-start ovarian stimulation in comparison with conventional ovarian stimulation to the Sterility and Infertility Section of the Spanish Society of Gynaecology and Obstetrics (SEISEGO). Researchers at the reproductive medicine clinic discovered that there are no significant differences between the results and they highlight that this is an advantage for commencing treatment and synchronising the donor and recipient.
