Multicenter StudyFive years' experience using oocyte vitrification to preserve fertility for medical and nonmedical indications.
To evaluate the results of controlled ovarian hyperstimulation (COH) for oocyte vitrification to preserve fertility for medical and nonmedical indications. ⋯ Patients who vitrify eggs for medical or nonmedical reasons perform similarly, as observed in this large series. This technique offers realistic expectations to both groups of patients to have a child with their own eggs. These data could be used to adequately counsel our patients.

Multicenter StudyHow and when human chorionic gonadotropin curves in women with an ectopic pregnancy mimic other outcomes: differences by race and ethnicity.
To investigate the hCG profiles in a diverse patient group with ectopic pregnancy (EP) and to understand when they may mimic the curves of an intrauterine pregnancy (IUP) or spontaneous abortion (SAB). ⋯ The rate of change in serial hCG values can be used to distinguish EP from an IUP or SAB in only 73% of cases. The number of women who had a change in direction of serial hCG values was associated with race and ethnicity.

Multicenter Study Comparative StudyMulticenter observational study on slow-cooling oocyte cryopreservation: clinical outcome.
To evaluate the efficacy of oocyte cryopreservation by a single slow-cooling protocol involving sucrose (0.2 mol/L) in the freezing solution. ⋯ Under the conditions tested, the clinical outcome of oocyte slow-cooling cryopreservation is reduced compared with fresh cycles. Nevertheless, in cases of inapplicability of embryo cryopreservation, oocyte cryopreservation should be offered to patients with surplus oocytes.

Randomized Controlled Trial Multicenter Study Comparative StudyLetrozole versus combined metformin and clomiphene citrate for ovulation induction in clomiphene-resistant women with polycystic ovary syndrome: a randomized controlled trial.
To compare the effect of letrozole with combined metformin and clomiphene citrate (CC) for ovulation induction in CC-resistant women with polycystic ovary syndrome (PCOS). ⋯ Letrozole and combined metformin-CC are equally effective for inducing ovulation and achieving pregnancy in patients with CC-resistant PCOS.
