Traditionally, ET in pigs is performed by open surgery (laparotomy), an effective but invasive and time\u2010consuming method associated with risks such as infection and herniation. To overcome these limitations, we developed a minimally invasive laparoscopic embryo transfer (LapET) method enabling ET into the oviduct using a sheep insemination device (Aspic, IMV Technologies, France). Seventeen gilts were synchronised with 17.6\u2009mg altrenogest daily for 16\u2009days, 10\u2009mg dinoprost on D15, 1250\u2009IU eCG on D16 and 1000\u2009IU hCG on D19, followed by LapET on D21. Each gilt received an average of 160 embryos, transferred 24\u201348\u2009h post\u2010somatic cell nuclear transfer (SCNT). Under general anaesthesia, gilts were placed on a surgical table in a 30\u00b0 incline Trendelenburg position. Three trocars were inserted to serve as ports for the laparoscope, a grasper and the Aspic pipette. The grasper served to expose the ovaries to confirm ovulation and to position the oviduct for embryo deposition. Following ET, the oviduct was released, instruments were removed and incisions were closed with surgical glue. Pregnancy was confirmed by ultrasonography, with 12 of 17 gilts (70.6%) diagnosed as pregnant, a success rate comparable to our recent laparotomy\u2010based SCNT ETs into the oviduct (71.4%; 10 of 14). These results demonstrate that LapET is a viable, fast, minimally invasive and effective alternative to traditional open surgery ET in swine.<\/jats:p>","DOI":"10.1111\/rda.70220","type":"journal-article","created":{"date-parts":[[2026,5,8]],"date-time":"2026-05-08T14:41:44Z","timestamp":1778251304000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Laparoscopic Embryo Transfer in Swine: An Effective Alternative to Traditional Open Surgery"],"prefix":"10.1111","volume":"61","author":[{"given":"H.","family":"Baldassarre","sequence":"first","affiliation":[{"name":"Department of Animal Science McGill University  Quebec Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
