These advantages make the development of a minimally invasive and repeatable procedure in pigs enticing, but simultaneously magnify the anatomical constraints. For decades, the swine industry has struggled to establish a universal procedure to collect pre-implantation embryos from pigs due to their long and convoluted uterine horns (UHs). Thus, the objectives were to evaluate the benefits of employing a transitional surgical model by shortening UH tissue using a 40 cm ipsilateral resection and assess the compensatory ovulatory response following an ovariectomy. The surgery was deemed successful as the UH was resected and the contralateral UH was fully ligated. The dam- and sire-line gilts exhibited ovarian hypertrophy between surgery and slaughter on the remaining ovary, illustrated by an increase in the number of corpora lutea (13.4 and 3.0 vs. 27.2 and 12; p &lt; 0.05, respectively) and intact ovary weight (11.9 and 7.7 vs. 25.9 vs. 38.7 g; p &lt; 0.05, respectively). This research is a vital step in assessing whether this interim surgical approach serves as a valuable method to advance the development of non-surgical techniques to collect pre-implantation embryos in pigs.<\/jats:p>","DOI":"10.3390\/ani15162366","type":"journal-article","created":{"date-parts":[[2025,8,12]],"date-time":"2025-08-12T15:51:02Z","timestamp":1755013862000},"page":"2366","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of an Ipsilateral Uterine Horn Resection and Ovariectomy Surgical Model in Gilts for Embryo Collection"],"prefix":"10.3390","volume":"15","author":[{"given":"Mikayla E.","family":"Ewasiuk","sequence":"first","affiliation":[{"name":"Department of Agricultural, Food, and Nutritional Science, University of Alberta, Edmonton, AB T6G 2P5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard R.
