An international group of scientists from the USA, Canada and Switzerland develops an injection that can create a contraceptive implant in the human body. It is reported by The Guardian.
Modern contraceptive implants have been operating for several years and are convenient in that they do not require daily use of pills: hormones enter the blood gradually. However, only doctors who have undergone special training can install them: the implant is implanted under the skin using a small incision.
In turn, contraceptive injections are easier to use, but their effect persists for only three months.
The new development, according to scientists, can combine the advantages of both methods and benefit in regions with poorly developed medical infrastructure. In addition, such injections are suitable for the treatment of HIV, tuberculosis, schizophrenia, chronic pain or metabolic diseases.
According to researchers, the injection involves the introduction of microcrystals of the synthetic version of the hormone progesterone contained in the solvent that is poorly mixed with water. Once in the body, the solvent interacts with the biological fluid, and microcrystals, on the contrary, “stick together” each other, which leads to the creation of a solid implant.
It is noted that the new technology has already successfully passed rates on rats.
