  1. Ginther O. An FSH booster surge for resurgence of the preovulatory follicle in heifers. Domest Anim Endocrinol. 2018;65:90-94 pubmed publisher
    ..It is not known whether the booster surge and resurgence of the preovulatory follicle are essential for complete and normal maturation of the follicle and oocyte and for ovulation. ..

    ..These novel findings may complicate studies on the mechanisms of follicle selection. ..

    ..Knowledge on follicle diameters for the different deviation classifications should be considered in studying follicle selection especially when terminal follicle sampling is done before expected deviation. ..
  6. Ginther O, Hoffman M. Interactions of side (left and right ovary) with the number of follicles per ovary and with the intraovarian relationships between dominant follicle and corpus luteum in heifers. Theriogenology. 2016;86:907-913 pubmed publisher
    ..Future studies on the effect of side on luteal or follicle dynamics could be incomplete or misleading if intraovarian patterns are ignored. ..

  8. Ginther O, Siddiqui M, Baldrighi J, Araújo E. An intraovarian mechanism that enhances the effect of an FSH surge on recovery of subordinate follicles in heifers. Domest Anim Endocrinol. 2017;59:67-74 pubmed publisher
    ..Our interpretation is that the intraovarian mechanism that enhances the stimulatory effect of FSH on recovery of subordinate follicles was effective only in RO and only when it contained a DF. ..
