Procedure for conception

A man whose semen is pure and who has himself kept celibacy for a month (the verse: a month or more) unites, with care, with a woman whose artava is pure (the commentary: who has also kept celibacy for a month) from the fourth-day bath onward. The commentary explains that the first three days of menstruation are left out and the period for procreation runs to the tenth or twelfth day from the start, and that the woman is to be pleased with loving words and the like as the kamashastra teaches. Wishing a son he goes to her on the even nights (fourth, sixth, eighth, tenth); wishing a daughter, on the odd nights (fifth, seventh, ninth).
