You Ask — We Answer

Dr. Fabio Castiglione Urologist London

Should men be concerned about watery semen? Does it affect their fertility?

Semen is usually a thick, whitish-gray liquid that is propelled out of the penis when a man ejaculates. It is made of seminal fluid (secreted largely by the seminal vesicles and the prostate gland) and sperm (produced by the testes).
At times, men might find that their semen is watery rather than thick. This situation can signal a fertility problem, but that is not always the case.
Semen might also change color depending on a man’s health.

Are there options for men with anejaculation who would like to father biological children?

Yes. There are three ways that sperm can be collected so that couples can conceive:

  • Penile vibratory stimulation (PVS). This method involves applying a penile vibrator to the tip of the penis. The vibrations move from the sensory nerves to the spinal cord, triggering ejaculation. This method works for about 60% of men, but men with spinal cord injury may not have as much success. PVS can be administered either in the doctor’s office or at home.

  • Electroejaculation. This procedure, usually performed under general anesthesia, involves electrically stimulating ejaculatory nerves near the prostate with a tool inserted through the rectum. The stimulation is gradually increased until the man ejaculates.

  • Extracting sperm from the testicles. In some cases, sperm can be removed from the testicles for in vitro fertilization use.
