Seated with her legs stretched out on her living room floor, Vivian Tung scrunched her bare stomach to find a spot where she could inject Rekovelle, a hormonal medicine used to stimulate egg production.

The 33-year-old Taiwanese brand marketing director had to inject herself daily over the two-week process it took to freeze her eggs.

Tung, who is single, is one of a rising number of women in Taiwan opting to freeze their eggs to give them the option to have a child later in life, even though under current laws they cannot use the eggs unless they marry.
