Explanation: The Shettles method suggests that female sperm (X-chromosome) are slower but more resilient, so having intercourse 2-3 days before ovulation gives them an advantage.
Details: Accurate timing is crucial for gender selection according to the Shettles method. The method is based on the different characteristics and survival times of X and Y chromosome sperm.
Tips: Enter your average menstrual cycle length in days. The calculator will determine the optimal day for intercourse to increase chances of conceiving a girl. Track your cycles for several months for best accuracy.
Q1: How accurate is the Shettles method?
A: The Shettles method has about 75% success rate according to some studies, but results can vary and it's not guaranteed.
Q2: What if my cycle length varies?
A: Use your average cycle length over the past 3-6 months for the most accurate calculation.
Q3: Should I use other methods alongside this calculator?
A: Yes, combining with ovulation predictor kits, basal body temperature tracking, and cervical mucus observation can improve accuracy.
Q4: Are there any medical interventions for gender selection?
A: Yes, procedures like PGD (Preimplantation Genetic Diagnosis) exist but are typically used for medical reasons and not widely available.
