The chances of conceiving for a regular couple who have 2-3 times of intercourse in a week, without protection are 25% (statistically). Out of a sample of 100 couples, in which 85% of the couple will conceive within a year of trying, 15% of the couple will take a year and half and the remaining 5% fall into the category of fertility or sub-fertility category. Such couples should opt for ART treatment, after consulting with a specialist. For more information, visit cloudninefertility.com
