The material for researches contains data received from the books of births and case records concerning the pregnant who gave births to twins in the Institute of Obstetrics and Gynecology of the Medical University in L\u00f3d\u017a between 1970-1998. The final analysis concerned only gestations lasting more than 29 weeks, without any complications (excluding prematurity and the growth-discordant twins), and when gestational age was exactly known. The selected group was finally composed of 188 pairs of twins. The analyses considered relations between total birth weight of twins, the sex of newborn babies, parity, and the duration of gestation. The duration of the analyzed twin pregnancies was 35,6 weeks, including primiparous with 35,8 weeks, and multiparous \u2013 35,1 weeks. In the group of male-male twin pairs the average duration of pregnancy was 35,7 weeks, in unlike-sexed pairs \u2013 35,6 weeks, and in female-female pairs \u2013 35,5. In the group of the primiparous having male-male twin pairs the average duration of pregnancy was 35,1 weeks, unlike-sexed pairs \u2013 36,4 weeks and female female pairs \u2013 36,6 weeks, while in the group of multiparous relatively: 36,4, 35,4, 35,0 weeks. The total birth weight of the specific pairs of twins was from 2270 g to 6900g (average 4794g), while in 92% &lt;5500g. In the primiparous group it was 4908,1 g. and in the multiparous group \u2013 4663,1 g. Analyzing the total twins' weight according to the fetal gender and parity it was found that in primiparous with male-male twins - 4715,3, unlike-sexed \u2013 5271,6 and female-female \u2013 4967,5, whereas in multiparous relatively: 4961,5, 4692,6, 4414,0. The shortening of twin pregnancies was caused by the following factors: total body mass achieved by fetuses was &gt; 5500 g, presence of male sex in twin pregnancies (only in primiparous), and also the multiparity.<\/jats:p>","DOI":"10.1017\/s0001566000000088","type":"journal-article","created":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T06:04:58Z","timestamp":1469599498000},"page":"183-190","source":"Crossref","is-referenced-by-count":6,"title":["The Uterine Capacity Measured by the Total Twin Birth Weight and Duration of Twin Pregnancy"],"prefix":"10.1017","volume":"47","author":[{"given":"K.","family":"Malinowska","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Antosik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Balcerczak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,8,1]]},"reference":[{"key":"S0001566000000088_ref008","doi-asserted-by":"publisher","DOI":"10.1017\/S0001566000006747"},{"key":"S0001566000000088_ref014","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(91)90077-5"},{"key":"S0001566000000088_ref002","first-page":"122","article-title":"Perinatal problems \u2013 the second report of the 1968 British Perinatal","volume":"7","author":"Butler","year":"1969","journal-title":"Mortality Survey"},{"key":"S0001566000000088_ref009","doi-asserted-by":"publisher","DOI":"10.1017\/S0001566000006437"},{"key":"S0001566000000088_ref015","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(94)70211-X"},{"key":"S0001566000000088_ref016","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(88)80029-2"},{"key":"S0001566000000088_ref005","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(98)70079-1"},{"key":"S0001566000000088_ref001","first-page":"113","article-title":"The relation between inter-twin birth weight discordance total twin weight","volume":"93","author":"Blickstein","year":"1999","journal-title":"Obstet Gynecol"},{"key":"S0001566000000088_ref017","doi-asserted-by":"publisher","DOI":"10.3109\/00016349209041441"},{"key":"S0001566000000088_ref013","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(86)90596-X"},{"key":"S0001566000000088_ref003","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(97)70023-1"},{"key":"S0001566000000088_ref007","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(95)00566-8"},{"key":"S0001566000000088_ref010","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/S0095-5108(18)30409-3","article-title":"Biologic basis of term and preterm labor","volume":"20","author":"Mayers","year":"1993","journal-title":"Clin Perinatal"},{"key":"S0001566000000088_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/0029-7844(96)00106-8"},{"key":"S0001566000000088_ref006","first-page":"1","volume-title":"Multiple pregnancy and delivery","author":"Gall","year":"1996"},{"key":"S0001566000000088_ref012","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-994668"},{"key":"S0001566000000088_ref011","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9378(16)32628-X"}],"container-title":["Acta geneticae medicae et gemellologiae: twin research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0001566000000088","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,10]],"date-time":"2019-05-10T16:06:45Z","timestamp":1557504405000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0001566000000088\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,10]]},"references-count":17,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[1998,10]]}},"alternative-id":["S0001566000000088"],"URL":"https:\/\/doi.org\/10.1017\/s0001566000000088","relation":{},"ISSN":["0001-5660","2059-6324"],"issn-type":[{"value":"0001-5660","type":"print"},{"value":"2059-6324","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,10]]}}}
