Ve also proved ineffective, considering that SPRMs induce reversible and benign endometrial alterations generally known as progesterone receptor modulator-associated endometrial modifications (PAECs) in Int. J. Environ. Res. Public Wellness 2021, intramyometrial endometrium [54]. Indeed, Donnez and Donnez reported more extreme 18, 9941 7 of 12 adenomyotic lesions following ulipristal acetate (UPA) therapy, with greater numbers and severity of cystic adenomyotic lesions [73]. Conway et al. reported the worsening of various ultrasound characteristics of adenomyosis, concomitant together with the aggravation of sympseveral ultrasound characteristics of adenomyosis, concomitant with all the aggravation of toms in UPA-treated adenomyosis individuals [74]. symptoms in UPA-treated adenomyosis patients [74]. As adenomyosis is essentially estrogen-dependent, hormone therapies lowering mitAs adenomyosis is essentially estrogen-dependent, hormone therapies reducing mitigating estrogens could prevent intramyometrial development of endometrial glands. GnRH agigating estrogens may perhaps protect against intramyometrial development of endometrial glands. GnRH onists were as a result proposed to each tackle adenomyosis-related Plasmodium Inhibitor drug hyperestrogenism and agonists have been consequently proposed to each tackle adenomyosis-related hyperestrogenism reduce proliferative activity in ectopic lesions [75]. Having said that, while GnRH agonists and lower proliferative activity in ectopic lesions [75]. Having said that, even though GnRH aghave have lengthy been recognized for their efficiency in uterine volume and offering onistslong been recognized for their efficiency in reducingreducing uterine volume and symptom symptom relief, their use remains limited and resulting from their adverse unwanted effects supplying relief, their use remains restricted and quick term short term due to their adverse and, importantly, speedy disease recurrence has been has been upon therapy cessation negative effects and, importantly, rapid disease recurrence observed observed upon therapy [13,768]. As outlined by Vannuccini and Petraglia [13,72] [13,72] and al. [68], use of cessation [13,768]. Based on Vannuccini and Petragliaand Cope etCope et al. [68], GnRH agonists for the management of adenomyosis-related discomfort and bleeding must use of GnRH agonists for the management of adenomyosis-related discomfort and bleeding only be regarded as for short-term administration mainly because as a result of their menopausal should really only be regarded as for short-term administrationof their menopausal effects, initial flare-up flare-up impact, and slow reversibility. 1 study did nevertheless a higher effects, initial effect, and slow reversibility. 1 study did nevertheless report report a pregnancy price in adenomyosis subjects undergoing frozen embryo transfer after GnRH higher pregnancy rate in adenomyosis subjects undergoing frozen embryo transfer right after agonist pretreatment [79].
