Caitlyn Jenner revealed in her new memoir that she underwent successful gender-reassignment surgery in January.
According to the Daily Mail, Jenner disclosed her procedure in her new book, "Secrets of My Life," a memoir scheduled to hit shelves April 25. In it, she describes her many interactions with strangers who were curious about Jenner's transformation, most of whom wanted to know if she'd had the reassignment surgery.
"I am telling you because I believe in candor,” she explains, according to Radar Online. "So all of you can stop staring. You want to know, so now you know. Which is why this is the first time, and the last time, I will ever speak of it."
Gender reassignment surgery is much more successful when performing a male to female change, which Jenner experienced. In the procedure, the penis and testicles are removed and the urethra is shortened to help create a functional vagina.
"So why even consider it? Because it’s just a penis," wrote Jenner. "It has no special gifts or use for me other than what I have said before, the ability to take a whiz in the woods."
"I just want to have all the right parts. I am also tired of tucking the damn thing in all the time."
Jenner's gender reassignment decisions have become quite the pop culture saga, beginning with a 2015 interview with Diane Sawyer on "20/20," when Jenner revealed she identified as a transsexual woman and had suffered from gender dysphoria since her youth, according to ABC.
“People look at me differently. They see you as this macho male, but my heart and my soul and everything that I do in life -- it is part of me," Jenner said in 2015. "That female side is part of me. That’s who I am."
Jenner appeared on the cover of Vanity Fair magazine, making her the first openly-transgender woman to do so. Her re-entrance into popular culture as Caitlyn caused a stir among mainstream and social media, particularly when she received Glamour's "Woman of the Year" award in fall of 2015, according to Us Weekly.
Jenner was a medalist at the 1976 Olympic games, winning gold in the male decathlon as Bruce. After the victory, Bruce grabbed an American flag from a spectator and ran a victory lap with it, starting what is a now common practice among Olympic athletes, according to ABC.
"I am going to live authentically for the first time in my life,” Jenner tells Radar she remembers thinking hours after the surgery. "I am going to have an enthusiasm for life that I have not had in 39 years since the Olympics, almost two-thirds of my life."
