In men with retrograde ejaculation, the muscle at the opening of the bladder, which usually stops semen from entering the bladder during orgasm, does not close normally. When the muscle does not close properly semen flows back into the bladder.
Therefore, little or no semen is discharged from the penis during ejaculation, and the first urination after sex looks cloudy as the semen mixes with the urine.
Retrograde ejaculation is uncommon and usually harmless.
Retrograde ejaculation can happen after surgery to the prostate or the neck of the bladder. Diabetes, multiple sclerosis, spinal cord injury, and some medications, in particular medicines for high blood pressure and medicines to treat benign prostate enlargement, can also cause retrograde ejaculation. Depending on the causes of retrograde ejaculation, It may be a temporary or permanent condition.
Most men with retrograde ejaculation do not need treatment. The important message is that it does not cause serious problems. However, it is difficult for men with retrograde ejaculation to have a baby naturally.
For men wishing to have a family, sperm may need to be collected in other ways for use in assisted reproduction procedures such as in vitro fertilisation (IVF).
A fertility specialist can take sperm from the urine, or take sperm directly from the testes(Microscopic testicular sperm extraction).
There are some medicines which have shown some benefit in treating retrograde ejaculation. However, to start these medications it is important to consult a specialist who can explain to you the risks and benefits of these medicines.
