Chances of Conception

Q: What are my chances of getting pregnant?

A: Each month there is a 20-25% chance of getting pregnant, 50% of couples take 5-6 months, and 85% get pregnant after 1 year.
However, this answer is really incomplete without taking into consideration your personal circumstances:

• If you don’t ovulate, there is a 0% chance of getting pregnant
• If he has no sperm, there is a 0% of getting pregnant
• If you have had a tubal ligation, there is a 0% chance of getting pregnant
• If you have severe tubal disease which has closed off your tubes, there is a 0% chance of getting pregnant
• If you are over 35, your chance of getting pregnant decreases by about 3% each year
• If you are under 35 and have tried unsuccessfully to get pregnant for one year, your chances getting pregnant in the second year are less than in the first year.
• If you are 35 and over, and you have tried unsuccessfully to get pregnant for 6 months, your chances of getting pregnant in the next 6 months are less than in the first six months.
• If your menstrual cycle is irregular, your chances of getting pregnant are lower.
• If your corpus luteum phase is shorter than 12 days, your chances of getting pregnant are lower.
• If you ovulate irregularly, on different days of the cycle, your chances of getting pregnant are lower.
• If you ovulate late in the cycle, after cycle day 21, mathematically, you have a lower chance getting pregnant because there are less ovulations per year and also because implantation is less likely in a uterine lining that’s older than 3 weeks (after the last menstrual period).
• If you are underweight (BMI under 19.5) your chances of getting pregnant are lower.
• If you are overweight (BMI over 25) your chances of getting pregnant are lower.
• If you take certain medications (hormones or others) your chances of getting pregnant may change.
• If you had surgery on your cervix your chances may be lower.
• If you have an infection your chances may be less.
• If you use lubricants your chances may be less.
• If you have sex while standing or get up after sexual intercourse, your chances may be less.
