These muscle contractions are related to the sensations of orgasm for the male. [5] Sperm are produced in the testes and enter the ejaculatory ducts via the vas deferens. As they pass by the seminal vesicles, a fluid rich in fructose combines with the sperm. This addition nourishes the sperm in order to keep them active and motile. [6]
If both ejaculatory ducts are completely obstructed, affected men will demonstrate male infertility due to aspermia/azoospermia.They will suffer from a very low volume of semen which lacks the gel-like fluid of the seminal vesicles or from no semen at all while they are able to have the sensation of an orgasm during which they will have involuntary contractions of the pelvic musculature.
Additionally, when the woman is fertile, sperm is only transported to the side of the dominant ovary. [3] Involuntary vaginal contractions may arise from non-sexual causes. Involuntary spasm of the muscles around the vagina, usually caused by anxiety, can result in vaginismus. [4] [5] Vaginal contractions should not be confused with uterine ...

His penis exhibits noticeable contractions both during his ejaculation, and after he withdraws his penis from the vagina at 2:55, when the contractions cause his penis to bounce (which may be assumed partly voluntary) as his erection subsides. Semen can be seen dripping from the vagina after the penis is withdrawn.
Semen is moved into the urethra following contractions of the smooth muscle of the vas deferens and seminal vesicles, following stimulation, primarily of the glans penis. Stimulation sends nerve signals via the internal pudendal nerves to the upper lumbar spine; the nerve signals causing contraction act via the hypogastric nerves. [19]
Blood in the semen can cause a pink or reddish colour, known as hematospermia, and may indicate a medical problem which should be evaluated by a doctor if the symptom persists. [ 11 ] After ejaculation, the latter part of the ejaculated semen coagulates immediately, [ 12 ] forming globules, [ 13 ] while the earlier part of the ejaculate ...
