Well - thanks for the info. Funny, I am 37 and have three bio kids and some teenage foster children (4) and get pregnant ridicuously easily as well. I have also had a couple of recent miscarriages. Being a stay at home Mom (I was for 9 years) can be a recipe for low libido in some women. I think the lack of stimulation and the lack of spending any time alone pursuing your own interests just doesn't help. Is there anything she is interested in that you could support her in doing - yoga, karate, classes, whatever.... Sometimes just getting out of the house helps.

PS 37 yo women can be entering peri-menopause and can have crazy hormones - up one minute, down the next. It doesn't help.
