When surgery is indicated in women with an endometrioma, clinicians should perform ovarian cystectomy, instead of drainage and electrocoagulation, for the secondary prevention of endometriosis-associated dysmenorrhoea, dyspareunia and non-menstrual pelvic pain. However, the risk of reduced ovarian reserve should be taken into account.	Strong recommendation ⊕⊕○○
Clinicians should consider prescribing the postoperative use of a LNG-IUS system (52 mg) or a combined hormonal contraceptive for at least 18–24 months for the secondary prevention of endometriosis-associated dysmenorrhoea (Seracchioli et al., 2009; Lee et al., 2018; Song et al., 2018; Chen et al., 2020; Zakhari et al., 2021).

After surgical management of ovarian endometrioma in women not immediately seeking conception, clinicians are recommended to offer long-term hormone treatment (e.g. combined hormonal contraceptives) for the secondary prevention of endometrioma and endometriosis-associated related symptom recurrence.	Strong recommendation ⊕○○○
For the prevention of recurrence of deep endometriosis and associated symptoms, long-term administration of postoperative hormone treatment can be considered.	Weak recommendation ⊕○○○
Clinicians can perform ART in women with deep endometriosis, as it does not seem to increase endometriosis recurrence per se (Somigliana et al., 2019).	Weak recommendation ⊕⊕⊕○
