Some might call the collection process the best part. Your testicles are constantly producing sperm. During an ejaculation, the sperm stored in your epididymis are shot out and fresh sperm come in. It takes days to completely refill the epididymis. Testing too soon after an ejaculation will usually show a lower sperm count than your average.
Semen Collection After Vasectomy: Care Instructions
Fertility Education - Topics - Progyny
After your vasectomy, you need to be sure you are not making any sperm. You will have to give your doctor a semen sample to send to a lab. The lab will count the number of sperm and may check the semen for signs of an infection. You must wait for at least 6 to 8 weeks after the vasectomy to give your doctor the sample. This is because you may still have sperm in your semen for several weeks. You should also have ejaculated at least 8 to 10 times since the surgery. Use some type of birth control during sex until you no longer have sperm in your semen.
Needing to produce a semen sample, for either semen analysis or fertility treatment use, may lead to "performance anxiety" or the inability to ejaculate. This should be no surprise when you consider all the factors involved with producing the semen sample. Often the semen sample must be produced in the fertility clinic , in a room set aside for this purpose.
Refrain from any sexual activity including masturbation for at least 2 days and no more than 10 days. Longer or shorter periods of abstinence may result in a lower sperm count or decreased sperm motility. A private room is available for semen collection within close proximity of our laboratory and is recommended for collection. The semen specimen should be obtained by masturbation. Alternate methods may be discussed but are not recommended.
