Yes because fertile biomarkers are observable in the woman until she enters menopause. Sterilization, such as tubal ligation for women or vasectomy for men, disconnect reproductive system parts so that the egg and sperm cannot meet. Sterilization does not prevent ovulation from occurring or reduce sperm production. Couples can still track and chart biomarkers to determine fertile and infertile phases of the cycle so that the lifestyle of periodic abstinence can be lived. This lifestyle choice will grow your sexual relationship in a loving way, encouraging communication, caring for each other’s needs for affection and time spent together. Your children will be blessed as a result of your closeness.
