Post Coital Test

What is the post coital test? 

The post coital test is used to assess the interaction between the cervical mucus and sperm. Antibody reactions occur when the immune system mistakes sperm for invading pathogens, such as bacteria, and seeks to destroy them. Antisperm antibodies can be produced by the female, or rarely by the male, and when they are present in the cervical mucous, the sperm cannot survive.

How is the post coital test performed? 

The couple has intercourse at home and the female comes to the office two to twelve hours later. A sample of the cervical mucous is examined under the microscope and numerous incapacitated sperm indicate there may be an antigen antibody problem.
