Complications related to ovarian stimulation and oocyte retrieval in 4052 oocyte donor cycles

Effect of ovarian stimulation and oocyte retrieval on reproductive outcome in oocyte donors.

OBJECTIVE To assess whether there is an increased risk of infertility in women that have previously undergone ovarian stimulation and oocyte retrieval for oocyte donation. DESIGN Cross-sectional survey. SETTING Tertiary referral center. PATIENT(S) A total of 194 past oocyte donors. INTERVENTION(S) Telephone questionnaire. MAIN OUTCOME MEASURE(S) Incidence of infertility after oocyte d...

Oocyte maturity in repeated ovarian stimulation

OBJECTIVE During stimulated IVF cycles, up to 15% of oocytes are recovered as immature. The purpose of this study was to investigate the trend of oocyte maturity in repeated ovarian stimulation for IVF. METHODS One hundred forty-eight patients were selected who underwent two consecutive IVF cycles using same stimulation protocol during 2008 to 2010. Ovarian stimulation was performed with FSH ...

Early Pregnancy Loss Following Laparoscopic Management of Ovarian Abscess Secondary to Oocyte Retrieval

Hydrosalpinges adversely affect implantation in donor oocyte cycles.

Hydrosalpinges have been associated with poor in-vitro fertilization (IVF) outcome in some, but not all, studies, perhaps through endometrial effects. To determine whether hydrosalpinges affect IVF outcome via endometrial factors alone, we analysed the results of recipients of donor oocytes with hydrosalpinges, thereby controlling for confounding variables, while isolating the intrauterine envi...

The Impact of In vitro Oocyte Maturity on Developmental Potential of Embryos Derived from Controlled Ovarian Stimulation Cycles

Background and Aims: One of the major subjects for improving in vitro fertilization (IVF) outcome is the quantity and quality of retrieved oocytes. In vitro maturation (IVM) provides an opportunity for using immature oocytes routinely discarded in clinics. This study aimed at evaluating the quality of embryos derived from in vivo and rescue in vitro matured oocytes. Materials and Methods: Tota...
