If your partner is 41 and you have been trying for a year, you REALLY need to see a Reproductive Endocrinologist. Over 40, fertility drops rapidly, so sooner is better.
Good luck!
the say around 36hrs to replenish. but can differ. you should bd 4/5 days before ovulation and the day after.
Hi,
given your age and that your sperm are normal I would think that BD once a day, or at worst once every two days would be fine.
My doctor actually told me to have sex as frequently as we want (but at least daily) during the 'fertile' period.
Best wishes and hope you can be successful soon.
