This is a test involving the examination of the seminal fluid in regards to its volume (ml/cc) number/concentration of sperms usually read as number in million/ml, motility of the sperms (the sperm speed), morphology (the look of the sperms). Once scheduled for a semen test, be instructed to abstain from ejaculating for three to five consecutive days (not more and not less), shorter periods of abstinence result in lower counts than actually present, and longer periods of abstinence may yield sperms with poor quality. Usually the test is performed in specialized centres that are well prepared and private enough to host such examination. Once ready, you will be handled a sterile collection cup in which you will be asked to ejaculate after masturbation. Make sure you collect all the ejaculated semen and avoid spillage.
