TEL AVIV, Israel — Jewish and Arab, straight and gay, secular and religious, the patients who come to Assuta Hospital in Tel Aviv every day are united by a single hope: that medical science will bring them a baby.

Israel is the world capital of in vitro fertilization and the hospital, which performs about 7,000 of the procedures each year, is one of the busiest fertilization clinics in the world.

Unlike countries where couples can go broke trying to conceive with the assistance of costly medical technology, Israel provides free, unlimited IVF procedures for up to two “take-home babies” until a woman is 45. The policy has made Israelis the highest per capita users of the procedure in the world.

“It’s amazing when you think about it,” marveled Keren, 35, who asked to be identified only by her first name. She was seated in a waiting room at Assuta’s in vitro fertilization clinic, a beige canister of her husband’s frozen sperm at her feet. The sperm had been delivered from another hospital where she had her first IVF attempt three years ago, resulting in the birth of her daughter.
