The postcoital test (PCT), also known as the Sims test, Hühner test ,Sims–Hühner test, or cervical mucous penetration assay is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix .
The sperm–cervical mucus contact test is an in-vitro slide test used for detecting antispermal antibodies. [1] It is one of the investigations done for infertility. It should not be confused with Kurzrock–Miller test , where there is interface between the two materials; whereas in this test the materials are thoroughly mixed.
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
Drops of the resultant fluid are then placed on a test strip, which changes color to indicate fertility. A reddish line means a normal sperm count (at least 20 million per milliliter of semen); no ...

Semen analysis is a complex test that should be performed in andrology laboratories by experienced technicians with quality control and validation of test systems. A routine semen analysis should include: physical characteristics of semen (color, odor, pH, viscosity and liquefaction), volume, concentration, morphology and sperm motility and ...
In this test, sperm are incubated with several hamster eggs. After seven to twenty hours, the number of sperm penetrations per egg is measured. The hamster eggs have had the zona pellucida, the outer membrane, removed—hence, zona-free. [3] Having all eggs penetrated by multiple sperm is considered to be a positive sign for fertility.
A semen analysis typically measures the number of sperm per millilitre of ejaculate, and analyzes the morphology (shape) and motility (ability to swim forward) of the sperm (the typical ejaculate of a healthy, physically mature young adult male of reproductive age with no fertility-related problems usually contains 300–500 million spermatozoa ...
