Embryos derived from donor or patient oocytes are not different for in vitro fertilization outcomes when PGT allows euploid embryo selection: a retrospective study

Clinical and Translational Medicine, 2020
Background At our facilities, patients that received embryos using donor oocyte during in vitro fertilization (IVF), usually have had at least one failed attempt to produce at least one euploid embryo with their own oocytes; however, the current debate ...

Both Oocyte Hyperresponse and Oocyte Vitrification Are Safe Procedures Regarding Embryo Euploidy: A Real-World Study Involving Almost 200 000 Oocytes. [PDF]

Reprod Med Biol
ABSTRACT Purpose To ascertain whether ovarian hyperresponse and oocyte vitrification (OV) are associated with an increase in embryo aneuploidy. Methods Retrospective study involving 197 629 retrieved oocytes. We studied the euploidy rate (ER), the ER according to the number of retrieved oocytes (ERaRO) and according to the number of metaphase II ...

Aspiration of excess follicles before intrauterine insemination in high response cycles

Reproductive Medicine and Biology, Volume 21, Issue 1, January/December 2022., 2022
Abstract Purpose To assess the outcome of excess follicle aspiration before intrauterine insemination (EFABI) in intrauterine insemination (IUI) cycles with 4–6 follicles ≥14 mm. Methods A retrospective case–control study with 1559 patients undergoing IUI (donor and husband's sperm), of whom 86 underwent EFABI.

Strategies for managing Asherman's syndrome and endometrial atrophy: Since the classical experimental models to the new bioengineering approach

Molecular Reproduction and Development, Volume 88, Issue 8, Page 527-543, August 2021., 2021
ABSTRACT Endometrial function is essential for embryo implantation and pregnancy, but managing endometrial thickness that is too thin to support pregnancy or an endometrium of compromised functionality due to intrauterine adhesions is an ongoing challenge in reproductive medicine.

Initial ovarian sensitivity index predicts embryo quality and pregnancy potential in the first days of controlled ovarian stimulation

Journal of Ovarian Research, 2020
Background To determine if a modified ovarian sensitivity index (MOSI), based on initial follicular measurements and the initial follicle-stimulating hormone (FSH) dose, can predict the production of high-quality embryos for successful implantation ...

Freeze-all, for whom, when, and how

Upsala Journal of Medical Sciences, 2020
Background: The ‘freeze-all’ practice refers to the cryopreservation of all mature oocytes or viable embryos after ovarian stimulation. The development of the vitrification technique has been crucial to make this approach a reality, since it increases ...

Timing of paediatric orchidopexy in universal healthcare systems: international administrative data cohort study

BJS Open, Volume 4, Issue 6, Page 1117-1124, December 2020., 2020
International guidelines recommend orchidopexy before 12 months of age. This study, using international administrative health data, found that this was achieved in only a minority of cases and that there were socioeconomic inequities in this outcome. Guidelines not widely applied Background International guidelines in 2008 recommended orchidopexy for ...
