Hi I'm 32 years old had almost every test that can be done including making sure my tube are not blocked, all came back normal . My husband had his vasectomy reversed so we did a few iui's with him and not took, doc says his sperm showed clumping together, so she suggested I try donor sperm, I've done 2 cycle's of donor sperm with no meds and they did not take, reason for no med yet is because they say I ovulate naturally , so why did the donor sperm not take, I'm confused and concerned that it's due to their timing , if I get a surge at night , they don't have me in the next day, they wait 36 hrs.
