In vitro effect of recombinant human gonadotropins on meiotic competence of dog oocytes

, 2019
The reproductive biology of the domestic dog is unique among mammalian species; because of this, in vitro maturation (IVM) rate is still very low compared with other domestic animals in spite of attempts at improvement.

Membranous dysmenorrhea and decidual casts: A scoping review

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Membranous dysmenorrhea, characterized by the expulsion of intact endometrial tissue rather than gradual dissolution during menstruation, occasionally presents as a decidual cast—a complete triangular mold of the uterine cavity. This poorly understood condition is likely underdiagnosed.

Administration of Gonadotropins for Superovulation in Mice

, 2018
For experiments that require large numbers of preimplantation mouse embryos, such as microinjection of zygotes, gonadotropins are administered to females before mating to increase the number of oocytes that are ovulated (i.e., to induce superovulation ...
