Approximately 13 per cent of Swedish women between the ages of 20 and 29 say that they have had a prolonged period of coital pain, something which prevents them from enjoying a normal sex life and which can seriously affect their relationships.
The majority of these women suffer from vulva vestibulitis, which is characterised by lasting penetrative pain and tenderness in the region around the vaginal opening (the vulvar vestibule). The researchers believe that the pain is caused by a combination of factors, both physical and mental, but the condition is poorly understood and there is no simple effective treatment.
Gynaecologist Ulrika Johannesson has now demonstrated in her doctoral thesis that contraceptive pills affect the body in ways that can increase the risk of pain. Healthy women who are on the Pill have lower pain thresholds on the area around the vaginal opening, a greater number of superficial blood vessels, and a different mucosa profile than healthy women who do not take oral contraceptives.
“These women are healthy and experience no pain during sexual intercourse,” says Dr Johannesson. “However, it is possible that changes in their mucosae make them less resistant to mechanical stress, and this can cause microfissures. We believe that this, in combination with the lower pain threshold, can contribute to vestibulitis.”
Dr Johannesson’s thesis confirms previous research showing that long-term use of contraceptive pills can increase the chances of developing vestibulitis. However, she stresses that there is no reason for women to go off the Pill if they are not experiencing pain during sexual intercourse.
“The Pill is an excellent form of contraceptive, but if you’re taking it and if you start getting problems with fissuring and pain, you should contact your doctor or your clinic; it’s a good idea to then go off the pill for a while to see if the problems go away,” she says.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
