[30] [unreliable medical source?] Computer assisted semen analysis (CASA) is a catch-all phrase for automatic or semi-automatic semen analysis techniques.
Semen can be tested for sperm count, sperm motility, sperm morphology, pH, volume, fructose content, and acrosome activity. Checks are also made to identify undescended testicles and retrograde ejaculation, along with medical history, such as cancer treatment, radiation, drug use, etc.
Males from India had a 30.3% decline in sperm count, 22.9% decline in sperm motility, and a 51% decrease in morphology over a span of a decade. Doctors in India disclosed that the sperm count of a fertile Indian male had decreased by a third over a span of three decades. [82]
The second category can be thought of as sperm quality, the visually identifiable characteristics that lab techs and doctors believed to be correlated with functional ability to find and fertilize ...
A doctor or WHNP takes a medical history and gives a physical examination. They can also carry out some basic tests on both partners to see if there is an identifiable reason for not having achieved a pregnancy.

Men are fertile continuously, but their sperm quality is affected by their health, frequency of ejaculation, and environmental factors. [24] Fertility declines with age in both sexes. For women, the decline begins around the age of 32, and becomes precipitous at age 37. For men, potency and sperm quality begins to decline around the age of 40.
The research is mixed on whether cycling affects male fertility, including sperm—but doctors offer some tips on protecting your swimmers, if you have concerns.
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), cryopreservation of gametes or embryos, and/or the use of fertility medication.
