We think Women's History month should be every month.
But since it's (officially) just around the corner - in March - we're spotlighting the six women who changed the reproductive health and sex world as we know it.
See who made our list, below.
1. Margaret Sanger
Arguably one of the most iconic figures of the American reproductive rights movement, Margaret Sanger popularized the term "birth control" - and went on to open the first birth control clinic in the United States in Harlem in 1930. Sanger established many women's health organizations and is credited with founding the Planned Parenthood Federation of America.
2. Virginia Johnson
You may already know her story, as portrayed by Lizzy Caplan on Showtime's Masters of Sex. But Johnson's legacy dates back to 1957, where - along with William Masters - Johnson pioneered sex research, focusing on human sexual response and the diagnosis and treatment of sexual dysfunction.
3. Betty Friedan
Writer. Activist. Feminist. Friedan embraced hundreds of titles throughout the course of her life, serving as a leading figure in the women's movement of the 1960s. After penning her novel The Feminine Mystique in 1963, Freidan was elected the first president of the National Organization for Women (NOW) in 1966.
4. Gloria Steinem
A living legend, Gloria Steinem is often credited as the leader and spokeswoman for the feminist movement of the 1960s and 70s. Speaking to New York Magazine in 1969, Steinem said: "Honey, if men could get pregnant, abortion would be a sacrament."
In 2005, Steinem partnered with Jane Fonda and Robin Morgan to co-found the Women's Media Center, aimed "to make women visible and powerful in the media."
5. Ruth Bader Ginsberg
Serving as Associate Justice of the United States Supreme Court, Ginsburg is the second female justice in history, best known for her outspoken ways and for fighting to advance women's rights. In 2014, Ginsburg famously responded to the Hobby Lobby argument that the government should "assume the cost" of contraceptives by saying: "The nation’s only dedicated source of federal funding for safety net family planning services [is not designed to absorb the unmet needs of those already insured]."
6. Lena Dunham
Lena Dunham has more than earned her place on our list, serving as a whistleblower-actress-author-activist, all in one. Speaking up on major issues like equal pay, abortion rights, body shaming and more, one of our favorite memories of Dunham is when she poked fun at men's rights activists on Saturday Night Live.
