Clemens Bimek invented a shut-off valve for the vas deferens, the tubes that bring sperm from the testicles out of a man's body. The Bimek SLV Spermatic Duct Valve is essentially a vasectomy with a gummy bear-sized on/off switch that you control from outside. So far, Bimek himself is the only person outfitted with the devices. He's currently seeking investment and medical approval for commercialization in his home country of Germany and beyond. From the company site:

(In 1998, while) watching a health advice program on TV, Clemens Bimek saw a segment about vasectomies, an operation he had never heard of before. He then asked himself: “Why not just insert a valve instead?” At the time he passed the patent office in Berlin-Kreuzberg everyday on his way to the construction site, where he worked. One day he decided to do some research on the topic and discovered that a few developments had already been attempted in this direction, but to him, these methods seemed overly complicated and therefore impractical. Bimek had, from that point, begun to further develop his ideas and to work on a first prototype...
(In 2008, after developing the idea and prototypes) Clemens Bimek attempted to convince different urologists to perform the valve implantation on him. A few were prepared to do this, but were stopped by the ethics committee at each clinic. He finally found a microsurgical specialist, who allowed him to observe 3 vasovasostomies. The specialist stated that he was prepared to implant the valve for Bimek’s self experiment and even obtained approval from the relevant ethics committee.

As a woman, you do become less fertile as you get older, eventually culminating in menopause and the end of your potential babymaking years. But what does "less fertile" mean, and at what age, and how quickly does the drop-off in fertility happen?
According to this really fascinating piece by Jean Twenge at The Atlantic, some of the commonly cited scare stats — that one in three women ages 35 to 39 will not be pregnant after a year of trying, say — are based on extremely old data collected from historical birth records that don't necessarily reflect what's happening with real women who are alive right now. That statistic mentioned above, for instance, comes from French records (likely those collected by local church baptismal registries) for the years 1670 to 1830.
That matters because fertility is affected by things like quality of nutrition, infection rates, and even childhood illnesses — all of which have changed drastically for the average Western woman since the 19th century.
Look at more modern records, and the outlook for post-30 babymaking is completely different. Read the rest
As I write this, it is 1:17 am on Wednesday, June 20th, 2012.
I am lying awake in bed, trying to decide whether or not to have an abortion.
Of course, we don’t call it an abortion. We call it “a procedure” or a D&C. See, my potential abortion is one of the good abortions. I’m 31 years old. I’m married. These days, I’m pretty well off. I would very much like to stay pregnant right now. In fact, I have just spent the last year—following an earlier miscarriage—trying rather desperately to get pregnant.
Unfortunately, the doctors tell me that what I am now pregnant with is not going to survive. Last week, I had an ultrasound, I was almost 6 weeks along and looked okay. The only thing was that the heartbeat was slow. It wasn’t a huge deal. Heartbeats start slow, usually around the 6th week, and then they speed up. But my doctor asked me to come back in this week for a follow up, just to be sure. That was Tuesday, yesterday. Still my today. The heart hasn’t sped up. The fetus hasn’t grown. The egg yolk is now bigger than the fetus, which usually indicates a chromosomal abnormality. Basically, this fetus is going to die. I am going to have a miscarriage. It’s just a matter of when.
Because of these facts—all these facts—I get special privileges, compared to other women seeking abortion in the state of Minnesota. Read the rest
