Dealing with menstrual cycles on Earth is a challenge many women face regularly, but what happens when women menstruate in space? As space exploration increasingly involves women, understanding how
female astronauts
manage their periods becomes crucial.
A brief history of women in space
The journey of women in space began with Valentina Tereshkova, the first woman to fly in space in 1963.
Over 60 women have since followed her footsteps beyond Earth’s atmosphere. However, the question of managing
periods in space
has been a topic of discussion since the early days of space exploration.
Historical perspectives and challenges
In the early years, menstruation was cited as a reason to exclude women from space missions due to concerns about hormonal changes and microgravity effects. However, advocates for gender equality in space argued that men faced similar unknowns when venturing into space, suggesting women should be equally considered.
Rhea Seddon, one of NASA’s first female astronauts, recalled the pragmatic approach taken by women in space exploration: “Consider it a non-problem until it becomes a problem.” This approach paved the way for addressing menstrual management as a practical consideration rather than a prohibitive factor.
Menstruation in microgravity
Contrary to early concerns, women experience
menstruation in space
similarly to how they do on Earth. There is no evidence suggesting menstrual blood flows backward in microgravity conditions. Female astronauts have not reported any significant menstrual issues during their missions.
According to Varsha Jain, a gynaecologist and researcher, women have the choice to manage their menstrual cycles in space. They can opt to continue menstruating or use contraceptive pills to suppress their periods. This choice is influenced by practical considerations such as hygiene and the logistics of managing menstrual products in a spacecraft environment.

The logistics of managing menstruation in space include carrying menstrual products and handling waste disposal systems designed primarily for other purposes. The weight and space constraints on missions like the International Space Station (ISS) pose additional challenges.
Jain suggests that many female astronauts opt for oral contraceptive pills to suppress menstruation during spaceflight. These pills, which contain estrogen, can be taken continuously to avoid menstrual bleeding. This approach is safe and effective for maintaining astronaut health and reducing logistical challenges associated with menstruation in space.
Future considerations and alternatives
While contraceptive pills are a common choice, Jain highlights the potential for using long-acting reversible contraceptives (LARCs) in space. However, further research is needed to determine their suitability and safety in microgravity environments.
Moreover, estrogen-based contraceptives may offer additional benefits to female astronauts, such as preserving bone density in microgravity conditions, which is essential for long-term space missions.
