Does it feel right?
Will you feel ok about it in the future?
Or will you always wonder what might have been?
Will you always feel sad that your kiddo is not related to both you and your partner?
Will you, if you're the only one who isn't genetically related to your child, feel like the odd man out?

These are important questions to consider, very carefully, before proceeding.

And the truth is, using donors is not for everyone.
Some people feel a lot more comfortable adopting. It makes them feel like they are on a level playing field with their partners. They may also feel like adoption is much easier to explain to the child and everyone else than donor conception.
And others decide not to have kids (or any more kids)

The really important thing is to take your time and talk to people
who've adopted or used donor procedures before deciding. 

If you feel very strongly that you would never want to tell anyone about using a donor (including your kid)then that's an indication that you don't really feel comfortable with it
and  you are probably not ready to proceed. 

On the other hand, if you're at least 80% certain that you will be all right with using a donor, then that's probably good enough. As one woman said they other day "I'm willing to take a leap of faith that this is going to be all right for everyone and that we'll all be happy that I did."

A better approach is to go for similar body type/hair and eye color; to read the profiles of lots of donors with an open mind; and choose someone you feel some rapport with. You want to feel good about your donor--your attitude towards her will be conveyed to your child.

And don't forget, most scientists agree that personality is formed equally by nature and nurture and you are going to have a profound influence on who your kid grows up to be from day one. 

There's an article in yesterday's New York Times today at  on the continuing controversies re: gestational surrogacy and the lack of consistent laws governing it from state to state and country to country.  To read it click here

Opposition to surrogacy from the conservative religious right and some women's rights groups (including the National Organization of Women) continues to influence legislators in certain states, while intended parents and surrogacy agencies argue that when the needs of all parties are attended to surrogacy is a huge benefit to all involved.

As a result, there are huge discrepancies from state to state (in six states surrogacy contracts are void and unenforceable while in others in surrogacy is legal, and in many others there are no laws one way or the other).

I've heard the argument that surrogacy should be banned because  surrogates are coerced by the financial compensation exploited by the arrangement (and I must admit that from what I've heard about surrogacy in India--where destitute women are required to live in dormitories throughout their pregnancies--this can sometimes be the case!)

But the surrogates that I know are not desperate for the financial compensation, and actually drive a huge emotional/psychological benefit from being able to fulfill the long-cherished dreams of the intended parents.
Psychological screenings to determine whether this is the case for any particular prospective surrogate is critical in determining whether this is, in fact, the case.

At the clinic where I work, extreme financial need would disqualify the woman from becoming a surrogate because the risk of exploitation is simply too great. And the surrogates who do enter into contracts with intended parents are very well cared for emotionally and psychologically by the agencies they work with.

And the intended parents are also  screened  to insure that their is a true medical necessity for the use of a surrogate (and not a simple preference not to undergo the inconvenience of pregancy) they are not emotionally detached from the surrogate and her family.
