However, male sperm also die faster than female sperm. Since frozen sperm only live in the female genital tract for about 24 hours after thawing, this would reduce the chances of pregnancy altogether. The average is 8 months for all age groups combined. If you're approaching 40, you may want to consider a fertility evaluation before you even start inseminating. Statistically, intrauterine insemination combined with treatment, if indicated, will increase the chances of conceiving sooner for this age group.
Most sperm banks charge a registration fee or require a physician referral to use their sperm.
Most sperm banks can get your sperm to you within days or several weeks, depending upon their requirements for recipient registration. Start several months ahead, however, by getting a physical exam and lab tests to rule out pregnancy related risks for you, as well as genetic health risks for your child. Other recommended tests are a pap smear and cultures for Chlamydia. Some sperm banks also require testing for AIDS, Syphilis and Gonorrhea. Many sperm banks will ship to your home, but some will only ship to a physician.
