Is it true that clomid (clomiphene) decreases chance of conception at age 40? also, i have a severe prolapsed uterus is, can that decrease chance of conception?

Clomid (clomiphene) and others: Clomid (clomiphene) does not decrease chance of conception at any age: it is an ovulation induction drug, so improves - somewhat - chance of conceiving at any age. Prolapse is not strictly a fertility factor, tho with severe prolapse, intercourse can be difficult or painful. At age 40 roughly 50% of women cans till conceive, hope this helps.
