That's just the article's handwaving. The case report actually says:
> During follow-up at 3 years of age, routine ovarian surveillance showed Twin 2 to have gonadal dysgenesis, and prophylactic oophorectomy was performed.

In fact, it sounds like Twin 2 was already sterile. > Streak gonads are the defective development of the gonads in an embryo, with reproductive tissue replaced with functionless, fibrous tissue, termed streak gonads. [It is] a form of aplasia, resulting in hormonal failure that manifests as sexual infantism and infertility, with no initiation of puberty and secondary sex characteristics.
