Effect of hysteroscopic septum resection on subsequent in vitro fertilization-intracytoplasmic sperm injection outcomes in cases of primary infertility.

Objective: Women with septate uteri are at risk for subfertility, recurrent miscarriage, and preterm birth. It is not clear if hysteroscopic septum resection is beneficial to subsequent in vitro fertilization-intracytoplasmic sperm injection o (IVF/ICSI) outcomes in women with primary infertility.

Study Design: We analyzed all 278 women with uterine septum and primary infertility between January 2011 and January 2019. In this retrospective cohort study, the patients were divided into a surgery group and an expectant (non-surgery) group.

Results: Among them, 87 had a complete and 191 a partial septate uterus. The IVF-ET characteristics of the two groups showed no significant differences in the patients' age, body mass index, or basal follicle-stimulating hormone, luteinizing hormone, and estradiol levels (P>0.05). The miscarriage rate in those who underwent hysteroscopic septum resection, however, was significantly reduced (5.1% vs. 12.9%, P = 0.035). In contrast, the live birth rate between the two groups revealed no significant difference (51.4% vs. 43.6%, P = 0.1771), nor did the obstetric and neonatal outcomes (P>0.05).

Conclusions: Hysteroscopic septum resection can be recommended prior to IVF/ICSI.
