Ovulation can be predicted by testing Luteinising Hormone (LH) levels in either blood or urine. The surge of LH occurs approx. 40 hours before ovulation occurs.
- Eggs (oocytes – pronounced ‘oh-o-sites’) live reliably for 12 hours and up to 24 hours.
- Sperm live reliably up to 2 days, but can survive up to 5 days.
- Population data reveals that 85% of couples achieve a pregnancy within 12 months when they are not avoiding a pregnancy. Another 10% achieve a pregnancy within the following 12 months.
- Fertility rates decrease significantly as women age beyond the age of 35
- Miscarriage rates increase as a woman’s age increases, as a result of the increased proportion of genetically abnormal eggs being released.
- Males 38 years and older also are an independent risk factor for miscarriage, despite the age of the female partner.
