Unfortunately, resultant menopausal symptoms sometimes limit the tolerability and duration of such treatment. The use of gonadotrophin-releasing hormone agonists to treat these diseases can result in short-term hypoestrogenic and vasomotor side effects as well as long-term impacts on bone health and cardiovascular risk. The routine use of add-back hormone replacement has reduced these risks and increased patient compliance, making this group of drugs more useful as a medium-term treatment option. The estrogen threshold hypothesis highlights the concept of a \u2018therapeutic window\u2019 in which bone loss is minimal but the primary disease is not aggravated. It explains why add-back therapy is appropriate for such patients and helps to explain the basis behind new developments in the treatment of hormonally responsive gynaecological conditions such as gonadotrophin-releasing hormone antagonists and progesterone receptor modulators.<\/jats:p>","DOI":"10.1177\/2053369114568440","type":"journal-article","created":{"date-parts":[[2015,3,23]],"date-time":"2015-03-23T00:01:01Z","timestamp":1427068861000},"page":"16-23","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Minimising menopausal side effects whilst treating endometriosis and fibroids"],"prefix":"10.1080","volume":"21","author":[{"given":"Paul D","family":"Simpson","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Norfolk and Norwich University Hospital, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James S","family":"McLaren","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Croydon University Hospital, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janice","family":"Rymer","sequence":"additional","affiliation":[{"name":"Department of Gynaecology, King\u2019s College School of Medicine, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward P","family":"Morris","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, Norfolk and Norwich University Hospital, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"301","published-online":{"date-parts":[[2015,3,22]]},"reference":[{"key":"bibr1-2053369114568440","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2011.08.021"},{"key":"bibr2-2053369114568440","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra0804690"},{"key":"bibr3-2053369114568440","unstructured":"Shaw RW.
