There are a few steps you can take at home to increase your chances of getting your partner pregnant:
Increase frequency of sex. Having sexual intercourse every other day around the time of ovulation increases your chances of getting your partner pregnant. However, ejaculating more often than that may reduce your sperm count
Have 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. Experts generally recommend having intercourse every two days near the time of ovulation. This will ensure that sperm, which can live several days, are present when conception is possible.
Avoid the use of lubricants. Some products such as Astroglide or K-Y jelly, lotions, and saliva have been shown to reduce sperm movement. Ask your doctor about sperm-safe lubricants.
