Grounded in real clinical data and showing where you statistically stand for natural conception, In Vitro Fertilization (IVF), and egg freezing.
Irregular cycles can indicate anovulation, which directly affects your probability.
Chronic stress can suppress the hormone surge that triggers ovulation.
BMI = weight in kg ÷ (height in m)2. Example: 65 kg ÷ (1.68 × 1.68) = 23 → normal. Not sure? Calculate your BMI →
Smoking can directly damage egg DNA and accelerate ovarian aging.

Calculating natural conception probability
Mapping In Vitro Fertilization (IVF) success rates

Your fertility overview
Based on your inputs and published clinical data, women with your profile statistically have the following probabilities:
Natural conception—natural conception probability within 12 months
In Vitro Fertilization (IVF)—IVF success rate per cycle today
Egg freezing—chance to have a baby if you freeze eggs now
1. Natural conception and where you stand
—get pregnant naturally within 12 months
—at age X+2
Natural conception probability by age
Source: Compiled from Dunson et al. 2004, Steiner et al. 2017, Wesselink et al. 2017, and NICE CG156 population data, adjusted for your cycle, BMI, smoking, and stress inputs where applicable. Educational only - not individualized prediction.
2. In Vitro Fertilization (IVF) and your success rate today
—IVF cycles lead to a baby today
—at age X+2
IVF chance of a baby by age
Source: Compiled from SART (Society for Assisted Reproductive Technology) and HFEA national registries and ASRM / ESHRE practice committee guidance, adjusted for your cycle, BMI, smoking, and stress inputs where applicable. Educational only.
3. Egg freezing timing and success rates
—chance to have a baby if you freeze eggs now
—at age X+2
Study data: eggs needed
Chance to have a baby by number of eggs frozen at each age
Source: Compiled from Cobo et al. 2021, Doyle et al. 2016, SART retrieval-yield data, and ASRM committee opinion on planned fertility preservation, adjusted for your inputs where applicable. Educational only.
4. Donor eggs option
With donor eggs, the chance to have a baby jumps to approximately 50-55% per cycle - regardless of your age. This is because what matters is the donor's age (typically 21-30 years old), not the recipient's. For women where natural conception and self-egg IVF are becoming more difficult, donor eggs represent a path with genuinely strong, consistent outcomes. Many women find this worth understanding clearly, even if it's not the first choice.

Share the details we should take into account for your fertifacts™ research report
Add more personal details so we can look up your exact data and generate a report specific to your situation. None of these are required - but each one can make the report more accurate.
Your cycle
Used for month-precise age calculations.
From first day of one period to first day of the next. Normal range: 21-35 days. Short or long cycles can indicate hormonal patterns that affect ovulation.
Lifestyle
Multiple studies show alcohol above 5 drinks/week is associated with reduced fertility.
Research shows more than 200mg caffeine/day (roughly 2 cups) may reduce fertility.
Studies show very intense endurance training can suppress ovulation in some women by disrupting energy balance.
Mediterranean-style diets have the strongest evidence for positive fertility effects.
Sleep affects reproductive hormones. Chronic sleep deprivation can disrupt the hormonal cycle that triggers ovulation.
Please select at least one main source of stress (or the option that best applies).
Knowing where your stress comes from helps us point to the most realistic interventions in your report.
Cannabis has been linked to disrupted ovulation in some studies.
We will review what you're taking against the research evidence and tell you what is actually supported by studies.
Medical markers (if you have them)
A proxy for cardiovascular fitness. You can find this on a fitness tracker or measure manually.
AMH (Anti-Müllerian Hormone) is the most precise indicator of how many eggs you have left.
FSH (Follicle-Stimulating Hormone) measured on day 3 of your cycle shows how hard your body is working to stimulate egg development.
