Risk of first trimester spontaneous miscarriage among singleton gestations following ICSI and its relation to underlying cause of infertility

Study objective: To assess the association between the first trimester miscarriage rates among women undergoing intracytoplasmic sperm injection (ICSI) and underlying etiology of infertility. Design: Prospective cohort study. Setting: Ain Shams University maternity hospital. Materials and methods: The study included women who became pregnant with singleton pregnancy following ICSI as a treatment for different causes of infertility. Women were followed up throughout the first trimester of pregnancy up to 12 weeks’ gestation (10 weeks after the day of embryo transfer). Main outcome measure: First trimester miscarriage rate. Results: Two hundred and thirty four pregnant young women were included in the study, 164 (70.9%) women miscarried. The causes of infertility among these women were as follows: 41 (25%) mild male factor infertility, 40 (24.4%) severe male factor infertility, 45 (27.44%) tubal factor, 7 (4.27%) polycystic ovarian syndrome, 3 (1.83%) endometriosis, 20 (12.19%) unexplained and 8 (4.87%) multifactorial. Stepwise logistic multi-regression analysis showed that both maternal age (>31 years) and tubal block were the most sensitive discriminators for the prediction of first trimester spontaneous miscarriage among the study population (P < 0.01). Major conclusions: First trimester spontaneous miscarriage rates among pregnant women with singleton pregnancy following ICSI were related to maternal age >31 years and/or the presence of tubal block.
