Ejaculatory Dysfunction
Basic Information 
Clinical Presentation
Disease Forms/Subtypes
• Ejaculation failure (aspermia, anejaculation): The most common cause of ejaculatory dysfunction. It is an intermittent or continuous failure of emission of semen and ejaculation in spite of normal sexual arousal and persistent mounting and thrusting.
• Sperm accumulation syndrome (spermiostasis/spermastasis): Abnormal accumulation of sperm within the ductal system.
• Urospermia: Emission of variable quantities of urine during ejaculation.
• Premature ejaculation: Very rare affliction in which ejaculation occurs before adequate insertion.
• Retrograde ejaculation: Process by which semen passes backward through the bladder neck into the bladder. It can be partial or total.
Physical Exam Findings
• Possibly none; findings are variable depending on cause.
• Musculoskeletal or neurologic dysfunctions during mating or semen collection, such as failure to couple squarely and thrust; asymmetric hind limb weight bearing and thrusting; lateral instability; falling during thrusting or dismount; reluctance to mount or dismount; early dismount.
• Acute or chronic sources of pain affecting the urogenital tract (eg, epididymitis, scrotal inflammation).
• Acute or chronic lesions of the penis.
• Ultrasonographic examination of:
The accessory sex glands could show dilated (fluid filled) and/or hyperechoic areas of the ampullae.
