The desire to conceive can be intense -- and couples encounter problems more often than you might think. About one in ten couples will experience infertility.

A recent study in Scotland found that, among couples who have unexplained infertility problems, the use of two common treatments didn't seem to have any significant effect on whether or not they ultimately conceived. Doctors tested a drug that stimulates ovulation and artificial insemination against doing nothing except counseling couples on the need to have regular sex -- and they found little difference in the numbers of couples who became pregnant.

What do you think? Can infertility treatments work miracles?
