The Science Behind the Female Orgasm: Originally an Ovarian Matter (Maybe)
The female orgasm—it’s been researched enough to prove that it exists and what the female body undergoes before, during, and after orgasm. But another question remains: Does the female orgasm serve a reproductive purpose? We know why male bodies orgasm. From a solely reproductive lens, it serves as a way to trigger ejaculation and get sperm one step closer to fertilizing an egg. According to Women’s Health, during sexual stimulation, the vagina widens up toward the cervix while pelvic muscles tense up near the vaginal opening. After more stimulation prompts those muscles and nerves to build more tension, an orgasm happens as that tension is involuntarily released. “The big bang is the moment when the uterus, vagina, and anus contract simultaneously at 0.8-second intervals,” writes Nicole Beland for Women’s Health….

The Science Behind The Copper IUD: How Does Metal Work for Birth Control?
Most forms of birth control, in terms of understanding how they work, are fairly straightforward. Barrier methods like diaphragms and condoms physically prevent sperm from entering the uterus, and hormonal methods like birth control pills, NuvaRings, and Nexplanon administer dosages of hormones that disrupt ovulation. But there’s an outlier in the BC field: PARAGARD, also known as the copper IUD. It is different from its other T-shaped counterparts because it does not contain any hormones; copper is the contraceptive in this product. How does copper actually work to prevent pregnancy? Is this method as reliable as its hormone-based peers, like other IUDs and the Nexplanon implant? Medical mechanisms In a mechanism of action report by CooperSurgical, the company that makes the copper IUD, the pharmacology behind this birth control… Read more »
RJ Tech Talk: Male Contraceptive Pill
Hooray! Male birth control will be available by 2017. What is male birth control? The Parsemus Foundation, a company that works on making healthcare affordable, is working on developing Valgasel: a pill made for men that will prevent contraception from happening. Luckily for you, guys, this is not a hormonal method! It targets a physical mechanism that targets the sperms little tiny tails and stops them from swimming. Also, the process if reversible and sperm will completely viable once again. As with any form of contraceptive pill, a barrier method will also be required to prevent transferring STIs between partners. What happens inside of bodies that take Valgasel? When sperm are created and stored in the testis (aka balls), and when they make there way from their storage center to exit… Read more »
RJ Tech Talk: Egg Freezing
As new technology is being developed for reproductive health, many questions come up as to how each product can fit into the framework justice. Technology’s impact on gender, sexuality, and reproductive choices has vastly expanded over the past fifty years. I’ve chosen to explain oocyte cryopreservation, or egg freezing, one tech product I’ve been seeing in the media a lot and provide links to other sources that talk about its use within reproductive justice, controversial or not. Oocyte cryopreservation, also known as egg freezing, is a procedure where a woman’s oocytes (eggs) are extracted, frozen, and the preserved. The eggs can be thawed later on when the person wants to become pregnant, transferred after fertilization to the uterus as embryos. Recently, egg freezing has been in the news because Facebook… Read more »
