Caprine reproductive system; cumulus-enclosed germinal vesicle oocytes aspirate from antral follicles for embryo production; (#) the place in fallopian tube where the 1-8 cell-stage developed embryos are collected or transferred; (*) the place in the uterine tube where the morula-blastocyst embryos are collected or transferred (Mohammed and Kassab, 2015).

Rabbit offspring obtained after transferred embryos to uterus of surrogate mothers (Mohammed et al., 2011).
Figure 5:
Micromanipulation of germinal oocytes, Pro-Metaphase I and Metaphase II oocytes in addition to enucleolation of germinal oocytes (Mohammed 2006; Mohammed et al., 2008, 2010; 2019; 2022).
