<s>[INST] context: Post coital test (Sims or Huhner's test) is a test for evaluation of the potential role of Cervical factor in infertility.
It is designed to assess:

The quality of cervical mucus.
Presence and number of motile sperms in the female reproductive tract. after coitus.
Interaction between cervical mucus and sperms.
It gives an approximate idea of sperm count: (normally 10 - 50 motile sperms are seen per high power field in cervical mucus, if count is < 10 sperms/HPF it indicates the need for complete semen analysis).
Post coital test gives a very rough idea about sperm count, motility and morphology.
As far as fallopian tube block is concerned postcoital test has no relation.

Time of test:

It should be performed 1 or 2 days before the anticipated time of ovulation ,when maximum estrogen secretion is present.
For patients with irregular cycles, patients urinary LH surge may be helpful in scheduling the test.

Prerequisites for the test: - Abstinence of 2 days.

Intercourse to be performed 2 -12 hours before the test.
No use of lubricant. [/INST] question: Post coital test (PCT) is done for: | options: A: Cervical receptivity B: Sperm motility C: Absolute sperm count D: Viable sperm count e. Endometrial function | answer: A </s>
