How Baby Birth Probability Works

The probability of a baby being born depends on several biological and statistical factors:

• Mother's age and fertility status
• Father's age and sperm quality
• Duration of infertility treatment
• Historical conception and pregnancy rates

The calculator uses statistical models based on large population data to estimate these probabilities. It does not account for individual medical conditions or specific circumstances.

Key Factors Affecting Birth Probability

Mother's Age

Fertility naturally declines with age. The calculator accounts for this by applying age-specific fertility rates.

Father's Age

Sperm quality tends to decrease with age. The calculator adjusts probabilities based on the father's age group.

Infertility Treatment

For couples undergoing infertility treatment, the calculator includes success rates based on the duration of treatment.

Worked Examples

Example 1: Young Couple

A 28-year-old mother and a 30-year-old father with no infertility treatment:

• Mother's fertility: 95% (based on age)
• Father's sperm quality: 90% (based on age)
• Combined probability: 85.5%

Example 2: Older Couple with Treatment

A 38-year-old mother and a 42-year-old father with 6 months of infertility treatment:

• Mother's fertility: 70%
• Father's sperm quality: 60%
• Treatment success rate: 40%
• Combined probability: 10.8%
