A contraceptive implant is a thin and flexible rod that sits under the skin and exposes contraceptive drugs to the body for years. Although it is a The most effective form of contraceptives And avoiding the difficulty of taking a pill every day, the implant requires slight surgery, which can limit accessibility. To make life a little easier, researchers are creating a self-campaign contraceptive implant whose ingredients in which women can self-manage with single injections.
A group of researchers created the technology for self-injected contraceptive shots that work the same with contraceptive implants. Such as a Study Published in the Journal of Nature Chemical Engineering on Monday, a highly effective and long -term contraceptive method for women with easily access to treatment infrastructure will be more accessible. Additionally, the design can be used to manage other long -term ATTS such as HIV.
As a result of the new approach, researchers supply hormonal drugs called “self-realized long-acting microcistals” (slim). Once injected into the body, miniature crystals are assembled in an implant or an drug “depot” that releases the levonorgestroll with the loss of several months or years.

Vivian Fag, a mechanical engineer and research at the University of Stanford, said “MITS (MIT),” MITSE (MIT) says, “Excessive aim is to give access to many different forms of contraception that is easy to manage, consistent with the developing world, and a range of work periods have a range of work periods.” StatementThe
Dition Birth control shot Already more accessible than existing and contraceptive implants because patients can give their own shot without seeing a hospital or medical clinic. However, they are a little less effective and chronic than the implant, so they must handle every three months.
Researchers’ new contraceptive design joins with the long-term functionality of an implant with accessibility of self-administered shots. The challenge of self-administration technologies similar to slim, however, is the larger (and so painful) needle size required to injection. In contrast, the source of the team – teini crystal and a solvent (in this case a liquid compound called benzil benzoate) – allow for the use of many small needles.
“The needle size and liquid viscosity are important for the commercial translation of injectable,” Senior author of the study and a gastroenterologist at MIT and Women Hospital, Giovanni Traverso says, a mass general brigham says StatementThe “Our engineering challenge was to find a way of most comfortable for patients using small needles, which causes less injury or bleeding, and reduce the viscosity enough to easily apply with syringes in hand.”
Furthermore, Traverso and his colleagues can change the mixture to extend the duration of “drug release rate, maintain its duration by maintaining injection,” MIT graduate student conflict Park explained in the MIT statement. “This shows the tuition of our system, which can be made engineer for other therapeutic applications as well as appropriate dosing regiments in addition to different types of contraceptive needs.”
Although slim has not yet passed through clinical trials, the development of technology in the proinical models is more convenient and paved the way for the long -term actions of the effective future.
