    en.wikipedia.org/wiki/Ejaculatory_duct_obstruction

    Low-volume, runny/fluid semen (oligospermia) or no semen at all (dry ejaculation/aspermia) are a logical consequence of an obstruction downstream of the seminal vesicles which contribute most to the volume of the semen. Usually, men will be able to observe a runny/fluid, low-volume semen by themselves during masturbation.

    The subject is a 27-year-old healthy circumcised Caucasian male whose genitals are in a state of mild sexual arousal. During the course of the video, the subject's semi-erect penis produces a drop of pre-ejaculate (also known as preseminal fluid, Cowper's fluid, or "pre-cum"); this is the typical amount produced at one time by this subject ...

    en.wikipedia.org/wiki/Ejaculatory_duct

    Retrograde ejaculation empties the seminal fluid formed in the emission phase into the bladder of the male instead of expelling it through the urethra and out the tip of the penis. [4] This results in a dry orgasm, where orgasm may still be experienced but without expulsion of semen from the ejaculatory ducts.

    en.wikipedia.org/wiki/Retrograde_ejaculation

    Retrograde ejaculation occurs when semen which would be ejaculated via the urethra is redirected to the urinary bladder. Normally, the sphincter of the bladder contracts before ejaculation, inhibiting urination and preventing a reflux of semen into the bladder. The semen is forced to exit via the urethra, the path of least resistance.

    en.wikipedia.org/wiki/Hypospermia

    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.

    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.

    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.
