The "old" method is known as the "turkey baster" method, in which the semen is placed in a turkey baster.
Another method uses a cup called the instead softcup, which is meant to be used to collect menstrual blood.
Neither of these methods has medical approval.
Conceivex has a product that is in the process of FDA approval for home sale (all of the parts are approved & you can buy the kit with a prescription) - this uses a silicon cap that is placed over the cervix, with the semen inside. The kit includes everything you need - ovulation predictor sticks, a special condom, etc - its main disadvantage is the high price (around $300 for 3 cycles). On their site, I believe they have links to relevant medical research.
Whatever you do, just like any woman trying to conceive, choose the fertile time (use an ovulation calculator and possibly an ovulation prediction kit) and stay in the same position for about 20 minutes.
Good luck,
