Forcible, sudden expulsion; especially expulsion of semen from the male urethra, a reflex action that occurs as a result of sexual stimulation. Adj., adj ejac´ulatory. The three components of semen are expelled in quick succession. First to emerge is a lubricating fluid produced by the bulbourethral glands in the penis; next comes a fluid released into the urethral channel by the prostate, providing a neutral medium within which the sperm cells can swim; and lastly, the spermatic fluid, which has been stored in the seminal vesicles, is likewise injected into the urethral channel and ejaculated. Delivery of semen ejaculate into the bladder; seen in neurologic disease, diabetes, and occasionally after prostate surgery. Retrograde ejaculation The passage of seminal fluid into the bladder during the male orgasm. This is due to failure of closure of the internal urethral sphincter as a result of injury during prostatectomy, damage to the sympathetic nerves in the region during local surgery, spinal injury or diabetic neuropathy.

Retrograde ejaculation is a common side effect of medications, such as tamsulosin, that are used to relax the muscles of the urinary tract, treating conditions such as benign prostatic hyperplasia. By relaxing the bladder sphincter muscle, the likelihood of retrograde ejaculation is increased. Retrograde ejaculation Overview. Retrograde ejaculation (which can also present with Anejaculation) as its name implies, is a condition that describes backward flow of seminal fluid into the urinary bladder instead of forward, as is the norm during orgasm.This usually occurs because the neck or opening of the urinary bladder, which normally closes to block such retrograde flow, is unable to do so.
Infertility may result but various measures may be used to overcome this. Retrograde ejaculation.
