The most common sign of hypospermia is a low volume of semen during ejaculation. [1] The diagnosis is confirmed when one has a semen volume of less than 2.0 mL on at least two successive spermograms. [2] If hypospermia is caused by retrograde ejaculation, sign include cloudy urine after orgasm. There may not be any symptoms of hypospermia ...
Total motile spermatozoa (TMS) [25] or total motile sperm count (TMSC) [26] is a combination of sperm count, motility and volume, measuring how many million sperm cells in an entire ejaculate are motile. Use of approximately 20 million sperm of motility grade c or d in ICI, and 5 million ones in IUI may be an approximate recommendation.
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.
Asthenozoospermia—sperm motility below lower reference limit Azoospermia—absence of sperm in the ejaculate Hyperspermia—semen volume above upper reference limit Hypospermia—semen volume below lower reference limit Oligospermia—total sperm count below lower reference limit Necrospermia—absence of living sperm in the ejaculate
In a non-harmful environment outside the body, such as in a sterile glass container [32] the number of motile sperm decreases by approximately 5–10% [32] per hour. In contrast, in a latex condom, the quality decreases by 60–80% [32] per hour, rendering the sample unusable in a relatively short time.
Sperm motility is dependent on several metabolic pathways and regulatory mechanisms. The axonemal bend movement is based on the active sliding of axonemal doublet microtubules by the molecular motor dynein, which is divided into an outer and an inner arm. Outer and inner arm plays different roles in the production and regulation of flagellar motility: the outer arm increase the bea
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.
Sperm quantity and quality are the main parameters in semen quality, which is a measure of the ability of semen to accomplish fertilization. Thus, in humans, it is a measure of fertility in a man . The genetic quality of sperm, as well as its volume and motility, all typically decrease with age . [ 17 ]
