<unk>  is sometimes referred to as a "dry orgasm."<unk>  is one symptom of male infertility. A man may notice during masturbation that despite the occurrence of orgasm, no accompanying ejaculation was produced. Another underlying cause for this phenomenon may be ejaculatory duct obstruction. During a male orgasm, sperm are released from the epididymis and travel via small tubes called the vas deferens. The sperm mix with seminal fluid in the seminal vesicles, prostate fluid from the prostate gland, and lubricants from the bulbourethral gland. During climax, muscles at the end of the bladder neck tighten to prevent<unk>  flow of semen. In<unk> , these bladder neck muscles are either very weak or the nerves controlling the muscles have been damaged.
