Fly Me to the Moon: Unraveling How Female Astronauts Manage Menstruation in Space

Navigating Periods in the Cosmic Realm

Venturing into the vast expanse of space, astronauts face unique challenges that extend beyond the technicalities of space travel. For female astronauts, one such challenge is managing their menstrual cycles while orbiting the Earth.

The advent of female astronauts in space has sparked discussions and research on how they cope with this natural bodily function in the microgravity environment. While periods were initially perceived as a potential hindrance to space travel, the determination of women to explore the cosmos has led to innovative solutions and a deeper understanding of the female body in space.

Understanding Menstruation in Microgravity

Contrary to popular belief, the absence of gravity in space does not cause menstrual blood to flow backward. The menstrual cycle in space occurs similarly to how it does on Earth, with blood flowing out through the cervix. However, some concerns had been raised about the impact of microgravity on the menstrual flow, such as the potential for retrograde menstruation (blood flowing backward into the pelvic cavity). However, astronauts have not reported any such issues during their missions.

To avoid any potential complications, female astronauts have the option of suppressing their menstrual cycles using contraceptives such as oral birth control pills. This method allows them to pause their periods during their time in space, eliminating the need for menstrual products and the challenges of managing hygiene in the microgravity environment.

Practical Considerations and Challenges

Despite the availability of contraceptives, some female astronauts choose to have their periods in space. In such cases, they must consider the practical aspects of hygiene and waste management. Menstrual products, such as tampons and sanitary napkins, add extra weight to the limited resources available on spacecraft. Additionally, the disposal of used menstrual items presents hygiene concerns, as water is a precious commodity in space.

Engineers and scientists have dedicated efforts to designing adaptive solutions for female astronauts. For instance, specialized waste-disposal devices have been incorporated into spacecraft to handle menstrual blood, overcoming the limitations of the urine-processing assembly that was not initially designed for blood.

Benefits of Birth Control Pills in Space

Beyond their primary purpose of preventing pregnancy, oral birth control pills offer additional benefits for female astronauts. The main ingredient in these pills, estrogen, helps maintain bone density. Astronauts, both male and female, experience bone loss in the microgravity environment, and estrogen has been found to counteract this effect.

Furthermore, oral contraceptives regulate the menstrual cycle, reducing the likelihood of irregular periods, which can be uncomfortable and challenging to manage in space.

Alternative Methods for Period Suppression

While oral contraceptives remain the most common method of period suppression for female astronauts, other long-acting reversible contraceptives (LARCs) are also available. Intrauterine devices (IUDs) and subdermal implants offer reliable and effective means of preventing periods for extended periods, eliminating the need for pill intake and reducing waste.

To Bleed or Not to Bleed: A Personal Choice

Ultimately, the decision of whether to have a period in space is a personal one for each female astronaut. Some may prefer to suppress their periods for practical or medical reasons, while others may choose to experience their cycles naturally. Regardless of their choice, female astronauts are well-equipped with the necessary knowledge and tools to manage their menstruation in the unique environment of space.


The challenges of menstruation in space have not deterred female astronauts from pursuing their dreams of space exploration. Through research, innovation, and adaptability, they have overcome these obstacles, paving the way for future women to navigate this aspect of their physiology while contributing to the advancement of human spaceflight. As we venture further into the cosmos, the solutions developed to address menstruation in space will undoubtedly evolve, ensuring that female astronauts can participate fully and without hindrance in the exploration and discovery of our vast universe.
