   In her new memoir, The Secrets of My Life, the gold medal-winning Olympian–who confirmed her transition from male to female and revealed her new identity as Caitlyn in June 2015–says that she underwent gender reassignment surgery in January 2017, PEOPLE has confirmed. 
   
   “The surgery was a success, and I feel not only wonderful but liberated,” she writes in the memoir, according to RadarOnline, calling the decision to undergo the surgery “complex.” 
   
   Jenner says she decided to be open about the surgery in order to stop the questions and inquiries about when — or if — she would have it done. 
   
   “I am telling you because I believe in candor,” she says. “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.”

   “I just want to have all the right parts. I am also tired of tucking the damn thing in all the time.” 
   
   “Gender confirmation surgery is something I think anybody in my position, or the girls’ position, of course you look into,” Jenner previously said of undergoing the surgery on a 2016 episode of I Am Cait. “For me, I have no idea what the future holds.” 
   
   In October 2016, Jenner legally changed her name to Caitlyn Marie and her gender to female. 
   
   The Secrets of My Life is available April 25. ||||| Caitlyn Jenner has finally undergone genital surgery in her years-long transition from male to female, RadarOnline.com can exclusively reveal. 
   
   In the reality star’s new memoir, The Secrets of My Life, she claims she had the “Final Surgery” in January 2017, nearly two years after she publicly announced her identity as a trans woman in an explosive interview with Diane Sawyer. 
   
   “The surgery was a success, and I feel not only wonderful but liberated,” she writes in the new memoir, out April 25.

   The 67-year-old former Olympic gold medalist claims she came clean so fans will stop asking about her nether regions. 
   
   “I am telling you because I believe in candor,” she explains. “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.” 
   
   Earlier in the book, Jenner calls the surgery a “complex decision,” due in large part to the health risks associated with the operation.

   But, she says she still considers going under the knife to have “all the right parts.” 
   
   “So why even consider it? Because it’s just a penis. It has no special gifts or use for me other tan what I have said before, the ability to take a whiz in the woods,” the former I Am Cait star tells fans. “I just want to have all the right parts. I am also tired of tucking the damn thing in all the time.” 
   
   Two years earlier, on March 15, 2015, Jenner says she underwent breast augmentation and facial feminization surgery in order to become Caitlyn.

   “I am going to live authentically for the first time in my life,” she recalls thinking in the hours after the surgeries, following an initial freak-out. “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.” 
   
   As Radar previously reported, Jenner earned a cool $4 million advance for her hot new book.

target: – Caitlyn Jenner has a new memoir dropping April 25, and she makes a big announcement in it, People has confirmed: She underwent gender reassignment surgery in January, meaning her physical transformation from male to female is more or less complete. "The surgery was a success, and I feel not only wonderful but liberated," Jenner writes in The Secrets of My Life, per Radar. She had indicated back in 2016 during an I Am Cait episode that she wasn't sure when or if she'd undergo the procedure, which for a person born male means removing the penis and creating a vagina. She apparently decided to go for it, however, and to tell her fans in the interest of "candor"—and so everyone would quit bugging her about whether she'd had it done or not. "So all of you can stop staring," she writes. "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." She also adds, in typical Caitlyn style: "I am also tired of tucking the damn thing in all the time." (So yeah, that "sex change regret" story obviously didn't pan out.)
