PY - 2023 T2 - Current Medical Diagnosis & Treatment 2023 AB - A couple is said to be infertile if pregnancy does not result after 1 year of normal sexual activity without contraception. Up to 20% of couples experience infertility in their reproductive lives; the incidence of infertility increases with age, with a decline in fertility beginning in the early 30s and accelerating in the late 30s. The male partner contributes to about 40% of cases of infertility, and a combination of factors is common. CDC National Survey of Family Growth data from 2011–2015 noted that 12% of women in the United States aged 15–44 report impaired fecundity.
