[|Human|] Hi, may I answer your health queries right now ?  Please type your query here... are you more likely to let pregnant from sperm that is from a 43 year old who has very very rare sex or a 28 year old who has sex every few days. from a 28 year old woman.
[|AI|]  Hallow Dear, The woman is 28 years young; so very much in peak of the childbearing age. Now, the timing of intercourse is more important than the frequency of intercourse. The egg is released (ovulation) 14 days prior to the next expected menses; so it is easy to spot the day of ovulation in a woman who is having regular menstrual cycles. The egg has a life of 24 hours while the sperms are active for 3 days. Hence, a period of about a week around the day of ovulation is fertile period. So more frequent intercourse during this fertile period is more likely to result in pregnancy. Intercourse on the day of ovulation is more likely to be successful in achieving pregnancy. If the semen quality and the sperm counts are within normal limits (as reported by semen examination), then a male of 43 years or of 28 yeas should not make any difference as far as the conception is concerned. The key factor is that the sperms should find live egg within 3 days of intercourse. I hope this clarifies your doubts.
