Timing is everything in Infertility:
1. Intercourse within the fertility window.
2. Frequency- alternate days, but more is better but stressful.
3. Identify the window by mucus, BBT, LH kits.
4. Position or resting after intercourse does not matter.
5. Lubricants probably don’t matter but if required natural oils like canola oil, mineral oil can be used.
