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.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
