A pelvic examination to collect a cervical mucus
sample does not cause problems.
A postcoital test checks a woman's
cervical mucus after sex to see whether sperm are
present and moving normally. Results of the postcoital test may be shared with
you right after the test.

No sperm or a large number of
dead sperm are seen in the sample.

What Affects the Test
A postcoital test may not be
normal if you do not know the exact day of
ovulation. If the test is done at another time in your
cycle, the sperm cannot move through your cervical mucus.
What To Think About
Clumped or dead sperm may mean that the
cervical mucus has problems that affect the sperm or that you or your partner
antibodies against the sperm (immunologic
infertility). For more information, see the topic
Antisperm Antibody Test.
If a postcoital
test is abnormal, a sperm penetration test may be done. For more information,
see the topic
Sperm Penetration Tests.
Many couples find
it hard to have sex "on demand," especially when an examination must be done
soon after having sex.
