Most sperm banks require men to be age 18 to 39 to donate sperm, according to the Mayo Clinic, but it’s not a one-time affair. Many clinics require donors to commit to making regular deposits at least once per week — in some facilities, the requirement is two to three times per week — for at least six months to one year. There are also genetic requirements for donors. Some facilities require donors to meet certain height requirements — usually 5 feet 10 inches or taller — and smokers, drug users and those with genetic histories of certain diseases aren’t eligible.
One final point, for all the “civic duty” types – did you realize that if the Constitution of the United States were read literally, forced jury duty would be illegal (as would military conscription)? The Thirteenth Amendment to the United States Constitution clearly states that “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction”, and just because the courts have chosen to ignore that doesn’t mean that it’s not in the Constitution. And yes, the Sixth Amendment does guarantee the right of trial by jury, but it does NOT say that they can force people to be on a jury that don’t want to be there (the obvious implication is that they should pay people enough that they will want to do their civic duty, and not feel like they are suffering financial hardship). Of course the courts choose not to read the plain words of the Constitution and abide by them in this case, but those of you who think that it is right that citizens should be forced to serve on a jury do NOT have the moral high ground here, at least not if you believe we should all be subject to the Constitution of the United States.
If you have finished college and got your Optional Practical Training (OPT) work permit , this gives you the right to work for anyone in the US for one year, which theoretically means you can also work for the Military. The best way to find out is to speak with a military recruiter about these eligibility criteria . Military recruiters can be found in every college in the US. They are always looking for recruits and will be very happy to help you out. If one recruiter gives you discouraging news, talk to another recruiter from another Military branch. He or she may have different ideas.
