I wrote the following on the Women in Astronomy blog last year, and I think it's worth repeating today:
Reproductive freedom, up to and including safe and legal abortions, is vital to women in science precisely because it allows us to choose how and when to start our families, or even whether to do so at all. At nearly every forum on women in science or women in astronomy I attend, the subject of having children always comes up: when's the best time? what about childcare? can I get maternity leave? how do you balance work and family? These questions are hard enough to answer. It's made slightly easier by having the freedom to choose.
In light of the ongoging debate on health care reform and amendments to the bills designed to restrict access to abortion, I think it's vital now more than ever to think about what reproductive rights mean for all women. For my own part, I'll be making a donation to Planned Parenthood today.
