Rhythm and birth control questions in a DIY health column
Dear Dr Lamb answers fears about fertility windows, ovulation, sperm lifespan, and chromosome basics. The piece explains variability in cycles, ovum life about six hours, sperm survival up to two days, and how X and Y sperm determine a baby’s sex, then promotes Health Letter 5-12 and a request form via a New York postal address.
