A new gel-based vasectomy has proven effective in a group of monkeys, raising hopes it could one day provide a permanent but easily reversible male contraceptive option in humans. Vasalgel works by plugging the vas deferens, the two tiny tubes that convey sperm into a male's semen, researchers said. The gel "doesn't break down. It just sets up a little more, and sticks where you inject it," said lead researcher Catherine VandeVoort. She's a professor of obstetrics and gynecology with the University of California, Davis School of Medicine. Sixteen male rhesus macaque monkeys injected with the non-hormonal gel have proven incapable of reproduction, according to the study findings.

No females have become pregnant in the males' presence, even though they were housed together for at least one breeding season -- about 6 months. "We're over two years in a lot of these males we injected with this, and so far they've all remained infertile," said VandeVoort. "We know that because we check the parentage of every baby that's born at the primate center." VandeVoort is also a scientist with the California National Primate Research Center at UC Davis. Traditional vasectomies either sever, crush or tie off the vas deferens, causing tissue damage that can be difficult to reverse, VandeVoort said. But researchers hope to revise the Vasalgel plug to the point where a simple solution of water and baking soda would flush it out of the vas deferens, easily restoring a man's fertility, said study co-author Elaine Lissner.

The gel plug has been successfully flushed out of male rabbits in animal testing, but reversibility has not yet been perfected in primates, said Lissner, founder and trustee of the Parsemus Foundation, the nonprofit group funding development of the gel. The focus of the current study was to see whether Vasalgel would effectively prevent conception, Lissner and VandeVoort said. "This tells us whatever challenges we face, the bottom line is it has worked and been safe in animals similar to humans," Lissner said. The Parsemus Foundation, based in Berkeley, Calif., funded the primate study. Source: http://www.webmd.com/men/news/20170207/a-plug-instead-of-a-snip-for-male-birth-control

Finasteride (Propecia) - Prostate Health - Patient guide - Quick tips

People often focus on pill itself, yet propecia finasteride works better when broader treatment plan stays organized. It is often part of plan for patients treating hair loss or prostate related concerns. Medicine alone may not solve every concern, but it can play valuable role when patient and clinician keep plan clear and consistent. A good starting resource is https://lucasclinic.com/prostate-health/propecia-finasteride/. Reading medicine specific guidance helps patients understand dosing basics, expected effects, and why one person's schedule should not be copied by someone else. Even when friends use similar treatment, goals and safety details may differ. Routine has real value here. Patients often benefit from reminders, pill organizers, calendar notes, or symptom logs. Those tools sound simple, but they reduce skipped doses and help show whether medicine is improving original problem or causing new concerns. Patients should also remember that treatment sits inside prostate care, not in isolation. Sleep, diet, hydration, activity, and underlying conditions can shape how well plan works. That is why follow up visits should review whole pattern rather than one symptom in a vacuum. Follow through after prescription also matters. Refills should be planned before bottles run low, symptom notes should be brought to visits, and any major change in routine should be mentioned early. Many medication problems are easier to fix when clinician hears about them after first week of trouble rather than after several months of guessing. No medicine should be managed on autopilot forever. Symptoms that deserve prompt review include breast changes, persistent sexual side effects, or mood decline. Early contact matters because timely dose changes, lab checks, or alternative treatment may prevent bigger setbacks. For wider reading in same care area, see https://lucasclinic.com/prostate-health/. Looking beyond one pill often helps patients understand why follow up and whole plan matter. Best long term approach is usually straightforward: use medicine as directed, keep communication early, and treat follow up as part of treatment rather than optional extra step.
