Reveals that hydrosalpinx fluid reduces implantation rates and increases pregnancy loss, indicating a metabolic barrier in infertility.
Hydrosalpinx affects 10–30% of women with tubal factor infertility and is known to impair in vitro fertilization (IVF) outcomes by reducing implantation rates and increasing pregnancy loss. Although surgical interventions such as neosalpingostomy or salpingotomy can reduce the risk of pregnancy loss by approximately half compared with no treatment,1 the detrimental effects of hydrosalpinx on fertility have long been recognized. The embryotoxicity of hydrosalpinx fluid has been documented for decades in mouse models.
