Obstetrics and perinatal outcomes between elective single versus double blastocyst transfer in women younger than 35 years: A cross-sectional study.

Introduction: Clinicians have a positive attitude towards multiple embryo transfer in in vitro fertilization (IVF) cycles, considering increased live birth rates compared to single embryo transfer. We aimed to evaluate obstetric and perinatal outcomes among young women who became clinically pregnant after single & double blastocyst transfer.

Material-method: 545 women under 35 years who became clinically pregnant after fresh blastocyst transfer was evaluated retrospectively.

Intracytoplasmic sperm injection cycle success in patients under 35 years old with diminished ovarian reserve plus severe male factor.

Objective: We aimed to evaluate intracytoplasmic sperm injection (ICSI) outcomes in young patients with diminished ovarian reserve (DOR) plus severe male factor (SMF) compared with age-matched controls with DOR.

Study Design: A total of 189 infertile women under 35 years with DOR undergoing ICSI procedures were included retrospectively. Participants whose partners' sperm analysis was normal considered as the DOR group (n = 154) and whose partners' had SMF considered as the DOR + SMF group (n = 35).
