We sent 1600 questionnaires about this via the Victorian branch of the Australian Multiple Birth Association, to be returned anonymously. Parents were asked how their twins were conceived and whether those who used assisted conception would disclose this to researchers studying assisted conception, twin pregnancy or twin children, or to their children. Comments were invited. Altogether 975 (61%) questionnaires were returned and 389 (40%) indicated use of some form of assisted conception: 75 (19%) ovarian stimulation alone, 165 (42%) In Vitro Fertilisation, 132 (34%) Intracytoplasmic Sperm Injection, and 17 (4%) Gamete Intrafallopian Transfer, with 20 reporting use of donor eggs and thirteen donor sperm. Of those using assisted conception, the proportion reporting that they would not, or may not, tell researchers was 5% for assisted conception studies, 6% for twin pregnancy studies, and 7% for studies of twin children, while 7% reported that they would not, or may not, tell their children. From the comments (from 374\/975; 38%) it was clear that questions about mode of conception can be offensive to some parents of twins, unless there is a need to know. Further, the question \u2018are your twins natural?\u2019 should be avoided. We believe the question \u2018Did you need medical help to conceive your twins\u2019, followed up with specific questions, is more acceptable.<\/jats:p>","DOI":"10.1375\/twin.10.6.886","type":"journal-article","created":{"date-parts":[[2008,1,8]],"date-time":"2008-01-08T04:32:28Z","timestamp":1199766748000},"page":"886-891","source":"Crossref","is-referenced-by-count":6,"title":["\u2018Are You Asking Me If We Had Sex To Conceive?\u2019 To Whom Do Parents Of Twins Disclose Mode Of Conception and What Do They Feel About Being Asked?"],"prefix":"10.1017","volume":"10","author":[{"given":"Supriya","family":"Raj","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Morley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2012,2,21]]},"reference":[{"key":"p_1_162","doi-asserted-by":"crossref","first-page":"256","DOI":"10.5694\/j.1326-5377.1997.tb125049.x","volume":"167","author":"Bebe J.","year":"1997","journal-title":"Medical Journal of Australia"},{"key":"p_2_163","doi-asserted-by":"publisher","DOI":"10.1053\/sper.2002.34775"},{"key":"p_3_164","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(03)00659-9"},{"key":"p_4_165","doi-asserted-by":"publisher","DOI":"10.1375\/twin.9.6.707"},{"key":"p_5_166","doi-asserted-by":"crossref","first-page":"78","DOI":"10.1080\/00016340500334851","volume":"85","author":"Leeb-Lundberg S.","year":"2006","journal-title":"Acta Obstetricia Et Gynecologica Scandinavica"},{"key":"p_6_167","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/deh703"},{"key":"p_7_168","unstructured":"Miles, M. & Huberman, A.
