People mean so well, but they have no idea the harm or frustration it can cause.” Dwyane Wade Calls Wife Gabrielle Union ‘One Strong Individual’ Following Revelation She Had ‘8 or 9 Miscarriages’ Ari Perilstein/Getty Dwyane Wade and Gabrielle Union In her book, Union painfully recalled the three years of failed IVF cycles she experienced. “For three years, my body has been a prisoner of trying to get pregnant — I’ve either been about to go into an IVF cycle, in the middle of an IVF cycle, or coming out of an IVF cycle,” she wrote. 10 Celebrities on Dealing with Infertility Earlier this month, Union revealed that a recent diagnosis gave her insight as to why she’s had so much trouble getting pregnant. “Everyone said ‘You’re a career woman, you’ve prioritized your career, you waited too long and now you’re just too old to have a kid — and that’s on you for wanting a career,’ ” she said, before adding, “the reality is I actually have adenomyosis.” Adenomyosis is a type of endometriosis that only occurs in the uterus, according to the Seckin Endometriosis Center. While side effects include an enlarged uterus, extremely heavy and painful periods and chronic pelvic pain, the only cure is to undergo a hysterectomy, according to the Mayo Clinic. Wade previously praised his wife for her strength and perseverance. “My wife is one strong individual!!!” he tweeted in October 2017 following news of Union’s multiple miscarriages. Though she was constantly bloated from the hormones of IVF treatments, Union wrote in her book that she and Wade “remain bursting with love and ready to do anything to meet the child we’ve both dreamed of.”
