Being underweight, presented by a low BMI value, was observed in an analysis to decrease the total sperm count and semen volume. No significant changes were observed in sperm concentration and motility due to a low BMI. However, due to the lack of raw data, further research is needed to clarify the role of BMI in semen quality. [8]
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). This is the most common type of fertility testing.
Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia ).
What does it mean to have a low sperm count? ... In addition to the number of live sperm present, the sample is also examined for motility (how well the sperm move) and shape. Doctors can also run ...
Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.
Aspermia is the complete lack of semen with ejaculation (not to be confused with azoospermia, the lack of sperm cells in the semen). It is associated with infertility.. One of the causes of aspermia is retrograde ejaculation, because of that the sperm is kept into the bladder and the final ejaculate is 0 mL. [1]
Hypoprolactinemia is associated with ovarian dysfunction in women, [3] [4] and, in men, metabolic syndrome, [5] anxiety symptoms, [5] arteriogenic erectile dysfunction, [6] premature ejaculation, [5] oligozoospermia (low concentration of sperm in semen), asthenospermia (reduced sperm motility), hypofunction of seminal vesicles, and hypoandrogenism. [7]
The motility and shape of the sperm are important for this role. A man with poor semen quality will often present with fertility problems which is defined as a couple trying to conceive for over 1 year with no success. [ 16 ]
