Expert: BMI Can Help Determine Fertility

BOSTON -- Doctors in Boston believe a person's body mass index could affect their fertility.

"Estrogens are produced in fat, and the more fat tissue you have, the higher your estrogen levels will be," said Dr. Samuel Pang, a fertility specialist. "What it does is, it causes an imbalance in the body, and that can lead to problems with ovulation."

Pang said the best way to figure out a woman's ideal weight range is to use the body mass index.

"The BMI is the ratio of the weight to the woman's height, and so based on the woman's height, we can calculate her ideal or optimum body weight," Pang said.

A BMI between 18 and 25 is considered normal, and that's the range doctors say you'll have your best chance at getting pregnant.

"Even if they can't get down to their ideal body weight, usually any amount of weight they can lose, and keep off, is helpful," Pang said.

Pang said a man's BMI will also affect a couple's fertility because his excess weight can hurt his sperm production.
