Why don’t we do it in the lab?

Fucking for science. Where do the masturbators sign up?

…For the first time – after hours and behind locked doors in an examination room in the Heart Hospital in London – a scientist is attempting to capture three-dimensional moving picture (or 4D, time being the fourth dimension) ultrasound footage of human genitalia in the act of sexual congress.

Jing Deng, a senior lecturer in medical physics at University College London, has made his name developing a new technique for viewing anatomical structures in motion. His website includes fairly astonishing 4D ultrasound footage of, for instance, beating hearts. This kind of imaging gives surgeons a preview of the structure on which they’ll be operating, in motion and from any perspective. It allows them to see what the problem is before picking up the scalpel.

In his most recent paper, Deng filmed a 4D “erecting penis“. With genital imaging, the hope is that the technology may help diagnose and treat patients with vascular or structural abnormalities, such as Peyronie’s disease, in which scar tissue in the erectile chamber on one side of the penis causes painful, crooked erections. … In his penis paper, Deng mentions the possibility of one day soon capturing an ultrasound sequence of real-time two-party human coitus. He envisions the scan as a potentially useful diagnostic tool – for instance, in teasing apart the possible causes of dyspareunia (painful intercourse)….

I Get Aroused Without Touching My Genitals Due to PGAD | Betty Dodson with Carlin Ross

Have you heard of a condition called PGAD (persistant genital arousal disorder)? I am in physical therapy for this and I feel like a freak.I do not know anyone nor have i ever heard of anyone afflicted with this. However, the one good thing I have gained from having this is the relationship i needed to form with myself. I know every part of myself so well. I know all my pleasure spots and have to spend extra time with myself. I was diagnosed with this about five years ago and I have since learned to accept it but the shame is still there because most of the time I am the only one doctors have ever met and some doctors just think im a nymphomaniac.Maybe I am that too but the arousal comes without stimulation and sometimes screams at me for attention. As I have said, i am in physical therapy now to manipulate the muscles that are squeezing the nerve to my clit.So am I a freak or do others have this issue? Have you ever heard of it?

Sperm donation – Wikipedia

 For fun and profit:

… When a sperm donor provides his sperm through a sperm bank or fertility clinic he will usually enter into a contract to donate sperm for a specified contractual minimum period of time ranging from six to twenty four months. To donate sperm a man must generally meet specific requirements regarding age and medical history. In the United States, sperm banks are regulated as Human Cell and Tissue or Cell and Tissue Bank Product (HCT/Ps) establishments by the FDA. Many states also have regulations in addition to those imposed by the FDA. A man generally donates sperm at a clinic or sperm bank by way of masturbation in a private room or cabin, known as a ‘men’s production room’ (UK) or a ‘masturbatorium’ (USA). Many of these facilities contain pornography such as videos, magazines, and/or photographs in order to assist the donor to produce the ejaculate … more Sperm donation – Wikipedia, the free encyclopedia
