Sperm count and morphology can be calculated by microscopy. Sperm count can also be estimated by kits that measure the amount of a sperm-associated protein, and are suitable for home use. [30] [unreliable medical source?] Computer assisted semen analysis (CASA) is a catch-all phrase for automatic or semi-automatic semen analysis techniques.
This mucus allows sperm to survive in and travel through it. In contrast, when outside of the fertile window, the mucus does not stretch, is sticky, and is not clear. The stretch test can be performed prior to and immediately after urination. Mucus can be sampled with by either wiping with toilet paper or inserting a clean finger into the vagina.
Cervical mucus is examined for quality, viscosity and fern test. [1] A poor PCT may indicate sperm or mucus problems, including perhaps presence of immune factors that inactivate sperm. Also ovulatory problems and poor coital technique may affect the PCT. The test is useless in presence of cervical infection. [1]
What it looks like: Purplish lesions on the inner arms, legs, wrists, or ankles can signify lichen planus, a skin rash triggered by an overreaction of the immune system.
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).
Similarly, trying to determine the factors leading to a global decline in sperm count is far from an exact science, and the study's focus on cell phone usage might be obscuring more than it reveals.
Diagnosis has shown that fertility problems arise 35% of the time from males, 35% from female, 20% from combined issues, and 10% from unexplained causes. For the male, semen collection is a standard diagnostic test to ascertain problems with the semen quality , while females may undergo a number of tests including an ovulation analysis, x-ray ...
