Frozen\u2013thawed sperm were selected and used in the following treatments. Control group: Fert-TALP medium without heparin; heparin (HEP) group: Fert-TALP with heparin (10 UI\/ml); BSP1 group: Fert-TALP medium with BSP1 (10 \u00b5g\/ml for ejaculated sperm; 40 \u00b5g\/ml for epididymal sperm); HEP + BSP1 group: Fert-TALP medium with heparin (5 UI\/ml) and BSP1 (5 \u00b5g\/ml for ejaculated sperm; 20 \u00b5g\/ml for epididymal sperm) and determined <jats:italic>in vitro<\/jats:italic> capacitation rates in different interval times (0, 15, 30 and 60 min) using the chlortetracycline \ufb02uorescence (CTC) method. Also, we evaluated the development rates of oocytes fertilized with ejaculated or epididymal sperm into the same treatments. Capacitation was greater and faster when ejaculated sperm were treated for 60 min with heparin compared with other treatments. However, developmental rates were similar in all treatments. For epididymal sperm, the treatments with BSP1 presented higher capacitation and fertilization rates compared with heparin (<jats:italic>P<\/jats:italic> &lt; 0.05). The effects of heparin + BSP1 on capacitation and developmental rates did not cause any increase in capacitation or blastocyst rates compared with other groups for ejaculated or epididymal sperm. In conclusion, this study confirmed that either BSP1 and heparin can be used as capacitator agents for bovine ejaculated sperm during IVF. However, BSP1 seems to be more efficient compared with heparin for epididymal sperm. Furthermore, BSP1 and heparin have no synergic effects on sperm capacitation.<\/jats:p>","DOI":"10.1017\/s0967199420000374","type":"journal-article","created":{"date-parts":[[2020,8,10]],"date-time":"2020-08-10T08:07:25Z","timestamp":1597046845000},"page":"489-494","source":"Crossref","is-referenced-by-count":8,"title":["Assessment of binder of sperm protein 1 (BSP1) and heparin effects on <i>in vitro<\/i> capacitation and fertilization of bovine ejaculated and epididymal sperm"],"prefix":"10.1017","volume":"28","author":[{"given":"Paula","family":"Rodr\u00edguez-Villamil","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daiane","family":"Mentz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3052-8768","authenticated-orcid":false,"given":"Felipe Ledur","family":"Ongaratto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis Henrique","family":"Aguiar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose Luiz","family":"Rodrigues","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcelo","family":"Bertolini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8271-5733","authenticated-orcid":false,"given":"Arlindo A.","family":"Moura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2020,8,10]]},"reference":[{"key":"S0967199420000374_ref23","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2015.09.044"},{"key":"S0967199420000374_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2004.09.016"},{"key":"S0967199420000374_ref10","first-page":"217","article-title":"Seminal plasma proteins: functions and interaction with protective agents during semen preservation","volume":"65","author":"Manjunath","year":"2007","journal-title":"Soc Reprod Fertil Suppl"},{"key":"S0967199420000374_ref24","doi-asserted-by":"publisher","DOI":"10.1021\/jp203509r"},{"key":"S0967199420000374_ref26","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod52.6.1372"},{"key":"S0967199420000374_ref21","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0897.2011.01033.x"},{"key":"S0967199420000374_ref11","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod.108.074088"},{"key":"S0967199420000374_ref30","doi-asserted-by":"publisher","DOI":"10.1095\/biolreprod59.1.1"},{"key":"S0967199420000374_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/0093-691X(95)00271-9"},{"key":"S0967199420000374_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0378(01)00098-5"},{"key":"S0967199420000374_ref32","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7827-7-119"},{"key":"S0967199420000374_ref33","unstructured":"Yanagimachi, R (1994).
