Ex vivo experiments on Drosophila eggs show that physical pulling on the dorsal appendages can cause the resumption of meiosis (Endow and Komma, 1997), placing them into a hypotonic buffer causes them to swell and activate (Mahowald et al., 1983; Page and Orr-Weaver, 1997) and more recently, osmotic and hydrostatic pressure can activate the egg (Horner and Wolfner, 2008).
Various methods have previously been used to study this question, for example, physical pulling on the dorsal appendages of mature oocytes has been shown to cause the resumption of meiosis (Endow and Komma, 1997) and placing mature oocytes into a hypotonic buffer causes them to swell and activate (Mahowald et al., 1983; Page and Orr-Weaver, 1997).
Lactation causes a delay in ovulation in the postpartum period, and therefore a delay in the resumption of menses.

Follicles were chronically exposed in vitro to 3 or 300 nM BPA for 12 days, during which they matured under the influence of follicle stimulating hormone up to the large antral stage, when stimulation of ovulation by recombinant hCG and recombinant EGF caused resumption of oocyte maturation and development of oocytes to metaphase II, at day 13 of culture [ 38, 76].
But such a step would make it easier to move towards a resumption of diplomatic relations.
