Dr. Marcus Setchell was Queen Elizabeth's gynecologist for 18 years. Affectionately called the "royal gynecologist," he will retire after delivering Prince William and Kate Middleton's first child this summer.

Setchell has enjoyed an illustrious career. Aside from the honor of being the Queen's gynecologist, he delivered Sophie, Countess of Wessex's two children, cared for Sophie during her ectopic pregnancy in 2011, and performed Prince Charles' wife Camilla's hysterectomy in 2007.

According to Hello! Daily News, William and Kate's baby is due mid-July and will be delivered by 69-year-old Dr. Setchell in the Lindo Wing of St. Mary's Hospital in London. Prince Harry and Prince William were both born in the same hospital.

Dr. Setchell postponed his retirement to deliver the royal baby, and a source believes he would leave retirement to deliver Middleton's babies if the couple decides to have more.

"Marcus says he will retire after the baby is born but because he knows they are planning more children, he will probably have to take time out of his retirement to deliver those too," a source close to Marcus told the Mirror.
