Sperm Transmigration as a Cause of Ectopic Pregnancy

Abstract

This case represents the phenomenon of contralateral sperm transperitoneal migration: sperm gaining access to the left oviduct after entering the peritoneal cavity via the right oviduct. The ovum from the left ovary after being successfully fertilized could not be transported into the uterine cavity due to the previous segmental resection, ultimately resulting in an ectopic pregnancy.

Key Words:

• sperm
