Premature ejaculation (PE) is a male sexual dysfunction that occurs when a male expels semen (and most likely experiences orgasm) soon after beginning sexual activity, and with minimal penile stimulation. [1] It has also been called early ejaculation, rapid ejaculation, rapid climax, premature climax and (historically) ejaculatio praecox.
This means that the sperm is produced in the testes but on its way out, it gets misdirected into the bladder rather than coming out through the urethra. This can lead to a low volume of semen (hypospermia) or no semen production . Structural or functional damage to the bladder neck muscle causes the backflow of semen during the ejaculation.
Pre-ejaculate on the glans of the penis. Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as pre-cum) is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal and in general during sexual activity.
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).
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 ...
The term luteinizing comes from the Latin "luteus", meaning "yellow". [6] This is in reference to the corpus luteum, which is a mass of cells that forms in an ovary after an ovum (egg) has been discharged. [7]
Causes of complete asthenozoospermia include metabolic deficiencies, ultrastructural abnormalities of the sperm flagellum (see Primary ciliary dyskinesia) and necrozoospermia. [ 1 ] It decreases the sperm quality and is therefore one of the major causes of infertility or reduced fertility in men.
A more modern medical definition is the excessive release of semen with no accompanying erection or orgasm. [ 1 ] In Western medicine during the nineteenth century, spermatorrhea was regarded as a medical disorder with corrupting and devastating effects on the mind and body. [ 2 ]
