The WTA is introducing a new programme that will offer tennis players up to 12 months of paid maternity leave.
Financed by the tour's global partner, Saudi Arabia's Public Investment Fund, the WTA says it is the first time a comprehensive package of maternity benefits have been made available to independent, self-employed athletes.
As well as financial support, the more than 320 eligible players will also have access to grants for fertility treatment.
A WTA statement read: "PIF and the WTA on Thursday announced the introduction of the PIF WTA Maternity Fund Program, a groundbreaking initiative that provides eligible WTA players with the financial support and comprehensive resources to start or expand their families."
Former world No 1 Victoria Azarenka, who sits on the WTA Players' Council and has an eight-year-old son, said: "I'm honoured to introduce this programme, driven by players, and made possible with the support of PIF and the WTA.
"This marks the beginning of a meaningful shift in how we support women in tennis, making it easier for athletes to pursue both their careers and their aspirations of starting a family.
"Ensuring that programmes like this exist has been a personal mission of mine, and I'm excited to see the lasting impact it will have for generations to come."
Azarenka is one of a growing band of players who have returned to the tour after having children, with Belinda Bencic and Petra Kvitova the most recent new mothers to resume their careers.
They are among 50 players to have benefited from a special ranking protecting their previous level that can be used for up to three years after giving birth since it was introduced in 2019.
