Can the ovulation calculator help me conceive a boy or girl?
The Shettles Method suggests timing intercourse closer to ovulation for a boy and 2–3 days before for a girl — but this method has not been validated in clinical trials. Most reproductive medicine specialists do not endorse it. The most important use of the calculator is maximising your overall conception probability. If family balancing is a medical priority, discuss Preimplantation Genetic Testing (PGT) with a specialist.
