STUDY QUESTIONDoes paternal age affect semen quality and reproductive outcomes in oocyte donor cycles with ICSI?

Is oral medroxiprogesterone acetate (MPA) non-inferior compared to ganirelix with respect the number of mature oocytes (MII) retrieved at ovum pick-up (OPU) in oocyte donation cycles?MPA is comparable terms MII OPU cycles.Oral treatment MPA inhibits pituitary LH surge during ovarian stimulation infertile patients. Because its negative effect on endometrium, suppression combined freeze-all. Published reports indicate that both and pregnancy rates from these are short protocol GnRH agonists...

Abstract STUDY QUESTION What is the relationship between sperm DNA fragmentation and oxidative stress (OS) with increasing male age? SUMMARY ANSWER Sperm increases age likely related to both defective spermatogenesis OS levels. WHAT IS KNOWN ALREADY quality declines age. The presence of damage in a high fraction spermatozoa from raw semen sample associated lower fertility natural conception intrauterine insemination. DESIGN, SIZE, DURATION A retrospective cohort study 16 945 samples analysed...

Does time to ICSI affect reproductive outcomes?Biochemical and clinical pregnancy diminish progressively as between oocyte pick up (OPU) increases after fresh embryo transfer.Appropriate cytoplasmic nuclear maturation are of paramount importance ensure an optimal embryonic developmental competence. While is usually attained by the reaches OPU, cannot be readily assessed might incomplete. On other hand, excessive in vitro culture mature human oocytes can their ultrastructural characteristics...

Is oocyte vitrification/warming as efficient and effective using fresh oocytes in donation cycles?IVF with vitrified donor is less than oocytes, but its efficacy remains comparable to that of cycles.Oocyte vitrification used preserve the reproductive potential oocytes. A small number randomized controlled trials carried out by experienced groups have shown this technique provides fertilization, pregnancy, implantation ongoing pregnancy rates those However, large registry-based analyses...

What is the quality of life (QoL) and mental health infertile heterosexual couples from different nations (Italy, Germany France) undergoing cross-border oocyte donation (OD) in Spain?Women have lower QoL more anxiety than their male partners; overall French Italian German counterparts.In Europe, thousands move across national borders annually to seek ARTs, primarily OD, driven mainly by legal restrictions countries origin. Most research shows that infertility ARTs affect patients' QoL. The...

How long is the individualized training and stability of competence for embryo transfer (ET) technique? The technique easy-to-learn, hardly unlearned, should be by monitoring with learning curve-cumulative summation (LC-CUSUM) curves. Like many medical procedures, an operator-dependent technique. Individualized or standardized these procedures monitored to determine when acquired. This prospective, monocentric study involving five trainees was carried out between August 2011 November 2012....

Background: The Miami VA Healthcare System serves veterans in three South Florida counties: Miami-Dade, Broward, and Monroe, with an estimated veteran population of 175,000. To overcome geographical barriers facilitate the access to nephrology clinics, we implemented provider–patient tele-nephrology using secured videoconferencing. Methods: A retrospective descriptive study design was used evaluate effect clinic intervention. Multiple clinical indicators were included analysis: blood...

Can two different methods for oocyte vitrification, one using an open tool and the other a closed tool, result in similar survival rates? The rate was found to be higher method. Open vitrification is performed routinely donation cycles. Closed may slower cooling rates thus it less used, even though has been recommended order avoid risk of cross-contamination between material from patients. This prospective cohort study with sibling oocytes carried out fertility center July 2014 January 2016....

Purpose: This study aimed to compare reproductive outcomes after Reception of Oocytes from Partner (ROPA; also called reciprocal in vitro fertilization) with those fertilization/intracytoplasmic sperm injection (IVF/ICSI) autologous oocytes, lesbian couples. Methods: was a retrospective matched cohort couples performing first cycle either ROPA (n = 60) or IVF/ICSI 120) between February 2012 and May 2018. Couples were 1:2 by age the oocyte provider, day embryo transfer (ET), number embryos...

Purpose: The aim of this study is to evaluate the health oocyte donors and explain how they regard their experience in long-term.Materials methods: This a cross-sectional single fertility centre that consists telephone interview guided by semi-structured questionnaire covering several aspects reproductive personal experience.Results: At time interview, 84 out 121 women (69%) had children while 64 (53%) were already mothers at donation. Of 38 achieving pregnancy after donation, five reported...

Can sperm donation increase live birth rates following ICSI in advanced maternal age (AMA) patients?Sperm increases the rate AMA cycles.In practice, has been predominantly applied to overcome male infertility. The involvement of paternal and lower quality severe reduction fertility observed patients remains be clarified.Retrospective multicenter cohort study including data generated between 2015 2019 from 755 cycles achieving a fresh embryo transfer, which 337 were first homologous...
