I don't know if it helps or not but i do know that if a couple isn't having any luck and you give them a dr.'s check quite often one or the other sometimes both need baby boost. which i automatically give in later generations when my peeps marry and once it was funny with 6 children the father fell gravely ill and when i did the dr. exam in addition to needing the medicine to get better it said he may want to use baby boost if he wanted children. he was 59 and had 6 already the youngest of which had just left for college.
