A woman with an obstructed cervix has been successfully treated for infertility using a technique known as intraperitoneal insemination (IPI). The technique, described in a case report just published in BMC Pregnancy and Childbirth, is less invasive and cheaper than alternative infertility treatments, which involve the harvesting of a womans eggs.
Scott Sills from the Atlanta Medical Center and Gianpiero Palermo from the Cornell Institute for Reproductive Medicine describe how they were able to successfully assist the 37 year old women to get pregnant. Their decision to publish this research in an online open access journal allows this important study to be read by the widest possible audience.
In couples with healthy semen, standard fertility treatments such as intrauterine insemination are usually the most appropriate. However, these treatments cannot be used if a narrow or obstructed cervix blocks the path to the uterus. Such women are usually offered either corrective surgery to remove the blockage or invasive fertility treatments like gamete or zygote intrafallopian transfer. Sills and Palermo suggest that women who have no blockages in their fallopian tubes could receive intraperitoneal insemination.
Intraperitoneal insemination bypasses the cervix by injecting sperm through the vagina, directly into the pelvic cavity where eggs are released. In this case study, the patient was first treated with follicle stimulating hormone to induce ovulation after which a specially prepared sperm sample was injected into the pelvic cavity. Following the procedure progesterone was given to the patient for eight weeks. The procedure was a success and it is hoped that it will be a useful alternative to more complex fertility treatments in patients where a cervical factor contributes to their infertility.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
