Weight loss support before IVF could boost pregnancy chances—and reduce the need for treatment

Around 1 in 5 women of childbearing age are living with [obesity], defined by the World Health Organization as having a body mass index (BMI) over 30 kg/m². Compared with women in the healthy BMI range (18.5–24.9 kg/m²), those living with obesity are three times more likely to experience fertility problems and nearly twice as likely to have a miscarriage. Many turn to in vitro fertilization (IVF) in the hope of having a baby.
