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 ...

At the peak of arousal (0:57), orgasm occurs and semen is ejaculated from the penis in a series of rhythmic contractions. (In this demonstration, there are 15 strong contractions followed by 10 weaker contractions). Once arousal has peaked (1:35), the penis returns to its flaccid state, the scrotum loosens, and the testicles descend.
It is the opposite of hypospermia, which is defined as a semen volume of less than 1.5 mL. Hyperspermia alone does not appear to influence sperm health. However, large volumes of ejaculate may have lower concentrations of sperm, leading to low fertility. [3] [1] In some cases, high semen volumes can be a symptom of male accessory gland ...
Sperm count, or sperm concentration to avoid confusion with total sperm count, measures the concentration of sperm in ejaculate, distinguished from total sperm count, which is the sperm count multiplied with volume. Over 16 million sperm per milliliter is considered normal, according to the WHO in 2021. [8] Older definitions state 20 million.
Lecithin contains dietary precursors to choline, an essential nutrient, which was formerly classified as a B vitamin (vitamin B 4). [17] [18] Lecithin is a mixture of fats that contains phospholipids, including phosphatidylcholine, and the human body can convert phosphatidylcholine into choline.
A 1992 World Health Organization report described normal human semen as having a volume of 2 mL or greater, pH of 7.2 to 8.0, sperm concentration of 20×10 6 spermatozoa/mL or more, sperm count of 40×10 6 spermatozoa per ejaculate or more, and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid ...
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
