Ejaculatory Disorders

Ejaculatory Disorders

Ejaculation is the process of expelling semen from the male reproductive tract. This is commonly accompanied by orgasm. Several organs including the penis, seminal vesicles, prostate, testicles, and brain are involved in this complex activity. Disorders of this process can impair sperm from exiting the body.


Anejaculation is an inability to ejaculate. Either due to physical (e.g. spinal cord injury) or psychological factors, men may be unable to successfully ejaculate. Assisted ejaculation can assist in obtaining sperm to help achieve pregnancy.

Retrograde ejaculation

Retrograde ejaculation is a condition where semen is projected into the bladder rather than outside the body. This may be caused by damage to nerves or muscles (e.g. diabetes) involved in coordinating ejaculation. Treatments can aid in restoring normal ejaculation or collecting sperm from inside the bladder for use in reproduction.

Premature ejaculation

Premature ejaculation is a condition where a man ejaculates sooner than a patient or partner wish. It is estimated to affect more than 30 percent of men at some point in time. Behavioral therapy, topical, and oral medications can help prolong sexual encounters and improve sexual satisfaction.
