Transcervical hysteroscopic permanent sterilization is currently Federal Drug Administration (FDA) approved. The hysteroscopic approach obviates the need for general anesthesia and surgical incision. The device is a dynamically expanding micro-insert that, when placed in the proximal portion of the fallopian tube, generates a benign tissue response that results in anchoring of the device and subsequent occlusion of the tube. The current trial of 745 women seeking birth control from Australia, Europe, and the United States were evaluated for successful micro-insert placement at three months. Comfort, safety, and return to normal activity were evaluated. All patients were followed for five years and returned for annual gynecologic status. Procedure time was 18 minutes, 92% returned to work in one day. There were no reported pregnancies among these patients in 27,526 months. The transcervical approach for sterilization represents ease of application, low morbidity, and convenience to the patient.

Transarterial embolization (TAE) is an image-guided, minimally invasive procedure for treating various clinical conditions by delivering embolic agents to occlude diseased arteries. Conventional embolic agents focus on vessel occlusion but can cause unintended long-term inflammation and ischemia in healthy tissues. Next-generation embolic agents must exhibit biocompatibility, biodegradability, and effective drug delivery, yet some degradable microspheres degrade too quickly, leading to the potential migration of fragments into distal blood vessels causing off-target embolization.

Young adults' access to contraception is shifting after the June 2022 United States Supreme Court decision. This concurrent mixed-methods study measured young adults' use of and perceptions about tubal sterilization and vasectomy after the leaked opinion in May 2022. Using national-level medical claims data from IQVIA, we conducted difference-in-differences analyses of tubal sterilizations and vasectomies by age and state policy; using open-text survey responses from national MyVoice surveys in 2022 and 2023, we thematically analyzed young adults' perspectives.

In the future, human beings will surely expand into space. But given its unique risks, will humanity thrive in space environments? For example, when humans begin living and reproducing in space habitats or on other planets in the solar system, are there risks that future generations may suffer from adverse mutations induced by space radiation, or that embryos and fetuses will develop abnormally in gravitational environments that differ from that of Earth? Moreover, human expansion to other stellar systems requires that for each breed of animal, thousands of individuals must be transported to destination planets to prevent populations from experiencing inbreeding-related degeneration. In even more distant future, when humans have spread throughout the galaxy, all genetic resources on Earth, the planet where humans originated, must be permanently and safely stored- but is this even possible? Such issues with future space colonization may not be an urgent research priority, but research and technological development accompanying advancements in spaceflight will excite many people and contribute to technological improvements that can improve living standards in the present day (e.

Background: Female sterilization, a safe, permanent method of contraception that blocks the fallopian tubes, has been in use since the 19th century. The procedure necessitates informed consent, a critical step that has been marred by reports of forced sterilization since World War II. These incidents often stem from inadequate consent processes where ethical principles are overlooked or deliberately flouted.

Background: The penile suspensory ligament (PSL) plays a significant role in penile support and erection and its injury or congenital absence may result in functional impairment of erectile function.
Aim: To describe the diagnosis and surgical repair technique for PSL abnormalities and overall outcomes.
Methods: A comprehensive review of the literature was performed to understand the anatomic relevance of the PSL and historical management of PSL defects.
