There are steps you can take at home to increase your chances of getting your partner pregnant, including:
Increasing the frequency of sex. Having sexual intercourse every day or every other day beginning at least four days before ovulation increases your chances of getting your partner pregnant.
Having sex when fertilization is possible. A woman is likely to become pregnant during ovulation — which occurs in the middle of the menstrual cycle, between periods. This will ensure that sperm, which can live several days, are present when conception is possible.
Avoiding lubricants. Some products such as Astroglide or K-Y jelly, lotions, and saliva might impair sperm movement and function. Ask your doctor about sperm-safe lubricants...Consult infertility specialist for further information and treatment.
