2 years ago i done semen analysis test & its normal .now my doctor ask me to do these semen test again does this time result will same.

Here are some ...: No result for a test done on two occasions comes the same, but always with some variation as so-called normal range because not all expected variables in the patient, machine, and lab tech for testing remains identical. But, comparing the reports and reviewing clinical features over time will provide reasonable information for clinical use,

Likely will be same: Given your young age, a repeat semen analysis after only two years, should still be normal, unless: 1. You developed a medical condition or took a medication within the past 2yrs that could have impaired normal sperm production. 2. The original semen analysis you had was not from a reputable lab. Perhaps ur dr cannot find cause for infertility in your female partner, so he/she wants to recheck u.

Can Vary: Sperm can vary over time for lots of reasons. It is good to know if anything has changed. Also it is relatively simple to do without any harm.

Possibly: always good to double check these test results. Good luck, hope the results are good as last time.

May change: The test may show some variations, Your doctor might want to check additional tests like DNA content,.

Not really: certainly abstain from sexual activity and/or masturbation for 3 days before analysis.
