BACKGROUND A successful oocyte cryopreservation programme is of utmost importance where a limited number of oocytes can be inseminated per cycle, to overcome legal and ethical issues related to embryo storage, for oocyte donation programmes and for fertility preservation (especially for cancer patients). Vitrification has been recently proposed as an effective procedure for this purpose. METH...

Sperm DNA integrity is vital for successful fertilization, embryo development, pregnancy, and transmission of genetic material to the offspring. DNA fragmentation is the most frequent DNA anomaly present in the male gamete that has been associated to poor semen quality, low fertilization rates, impaired embryo quality, and preim‐ plantation development and reduced clinical outcomes in assisted ...

This is a report of a case of an egg recovery procedure completed with manual suction instead of the automated negative pressure suction. A 35-year-old woman who was undergoing in vitro fertilization (IVF) treatment had to undergo oocyte recovery using manual suction through a syringe instead of the automated negative pressure suction systems because of the failure of both the initial and repla...

Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....

ObjectiveTo determine whether 4 cytoplasmic granulation patterns of human metaphase II oocytes have a predictive value for in vitro fertilization outcomes.DesignA retrospective cohort study.SettingAn academically affiliated private clinical infertility and research center.Patient(s)A total 2,690 consecutive fresh autologous collected from women aged 41.2 ± 5.0 years between 2017 2019.Interventi...

BACKGROUND Minimal stimulation in vitro fertilization (mini-in vitro fertilization) is an alternative in vitro fertilization treatment protocol that may reduce ovarian hyperstimulation syndrome, multiple pregnancy rates, and cost while retaining high live birth rates. OBJECTIVE We performed a randomized noninferiority controlled trial with a prespecified border of 10% that compared 1 cycle of...

Purpose: To investigate the effect of BNT162b2 COVID-19 vaccine on women’s fertility. Methods: We prospectively collected data women patients undergoing In Vitro Fertilization (IVF) treatment after completion 2 doses vaccination between February and April 2021 (POST vaccine). For comparison, we reviewed records same before (PRE vaccine) up to 2019. Each woman served as self-control vaccination....

ObjectiveTo determine whether the ooplasm granulation patterns of donor oocytes, like those oocytes from poor-prognosis patients, are predictive in vitro fertilization (IVF) outcomes.DesignRetrospective cohort study.SettingAcademically affiliated private clinical infertility and research center.Patient(s)770 fresh 381 vitrified-thawed metaphase II young donors (aged 21.0–34.6 years) used for IV...
