Our surrogacy agency, Shared Conception, loves receiving your questions about surrogacy so please keep them coming. One question that weighs on most people's minds is this: Is there a weight requirement to become a surrogate?

There is no weight requirement but there is typically a BMI, or Body Mass Index, requirement.

Why does BMI matter for Surrogates?

BMI is a measure of your body fat based on your height and weight. The requirement is put in place for your safety and to also ensure that the transfer and pregnancy has the best possibly chance of being successful. Shared Conception typically screens surrogates because we want to make sure that a surrogacy journey is going to be the right choice for each individual who applies.

Each fertility clinic has their own BMI limit but most require the surrogate’s BMI to be 32 and under.
