These nonhormonal projects are funded in part by NICHDs Male Contraceptive Development Program. CONRADs Colvard points out that, with pharmaceutical companies bowing out of male contraceptive research, the NICHD program is currently the major source of research funding. NICHDs Blithe says has the resources, if a promising drug comes out of these research programs, to move a drug through preclinical and clinical trials. Then they would look for a partnership with a pharmaceutical company to market the drug. For a nonhormonal drug, that process could take more than a decade. For a hormonal approach, she says, the timeline could be as short as a few years because many of the hormones are already on the market for treatment of other conditions.. ...
Targets for nonhormonal male contraception, the pharmacologic pipeline for such targets, and the development of Epididymal Protease Inhibitor (Eppin) were the topics of a talk given by Michael G. ORand, PhD, at The Endocrine Society Annual Meeting in San Diego, CA.

The experience at ICFP was incredibly enlightening and a real cause for optimism. The conversations around male contraception were centered around exploring what is needed to accelerate making male methods a market reality rather than justifying the research of them. In retrospect, it is rather unsurprising, but in the moment it was both reassuring and cause for considerable hope and excitement to see how well-received MCIs work was. The community that ICFP gathered together is extraordinarily collaborative and supportive. Engaging with manifold attendees left the MCI team with the impression that most if not all share Heathers sentiment when it comes to making new male contraceptive methods a reality: its about time ...
STANFORD -- Combining vasectomy with existing technologies of cryogenic sperm preservation and artificial insemination could produce a reliable system for reversible male contraception. Because this is the only new approach to male contraception likely to become available in the foreseeable future, the military services should set up a large-scale sperm cryopreservation program in order to create public confidence in the approach, and to work out its technical, legal and ethical aspects, a Stanford chemist says. "Would it not be a dramatic gesture if the military were the vehicle whereby the responsibility for birth control would be more equitably shared by both males and females," says Carl Djerassi, professor of chemistry at Stanford University, widely known as the father of the birth control pill. Djerassi and Stanley P. Leibo, research professor at the University of Guelph, propose this new approach to birth control in the July 7 issue of the British science journal Nature. The absence of ...
Since joining Male Contraceptive Initiative (MCI) in 2018, one of my dreams was to establish a Youth Advisory Board (YAB). The seed of this idea was first planted when I was introduced to YTH, an organization that I now have the pleasure of calling close colleagues. I was immediately impressed by YTHs deliberate and outward-facing commitment to youth. It occurred to me that the inclusion of youth perspectives in sexual and reproductive health research, programs, and policy should be a best practice for all organizations. In the case of MCI, I believe it is a critical practice given that todays young men and their partners will be the first beneficiaries of non-hormonal, reversible, male contraceptive methods that are currently in development. ...
No effective hormonal contraceptive has yet been devised for men. Through their suppressive effect on gonadotropin secretion, GnRH antagonists inhibit both testosterone (T) production and spermatogenesis in animals. Long term administration of an antagonist alone would result in androgen deficiency; this would cause unacceptable physiological and behavioral sequellae in men. Therefore, androgen replacement must be included in any GnRH antagonist regimen used in human male contraception. We tested the hypothesis that the combination of a GnRH antagonist plus T would suppress spermatogenesis in the male primate to azoospermic levels while maintaining normal serum T levels. We examined the effects of the GnRH antagonist Deterelix [N-Ac-DNal(2)1-DpCl-Phe2-DTrp3-DhArg(Et2)6 -DAla10-GnRH], alone and with simultaneous T replacement, on sperm production and serum T levels in adult male monkeys (n = 22). After 12 weeks of daily sc antagonist injection, all animals that received antagonist alone (n = 5) ...
From birth control pills and injections, to intrauterine devices (IUDs), women have the benefit of being able to choose from a wide range of contraceptives. While some pharmaceutical companies have tried in the past to develop a male contraceptive, so far none has been successful at making a safe and effective male birth control.. As the Centers for Disease Control and Prevention (CDC) estimates that nearly half of all pregnancies are unplanned, there is a clear need for additional forms of contraception. Now, a company known as Revolution Contraceptives have developed a male non-hormonal contraceptive gel, named Vasalgel.. Last year, researchers tested Vasalgel in rabbits, and found that the product could rival vasectomies in terms of its successfulness as a long-term male contraceptive. A recent study - published in the journal, Basic and Clinical Andrology - tested the drug in monkeys and found similarly promising results.. Vasalgel is a high molecular weight polymer, which could offer a ...

Male contraceptives, also known as male birth control are methods of preventing pregnancy that primarily involve the male physiology. The most common kinds of male contraception include condoms, withdrawal or pulling out, outercourse, and vasectomy. In domestic animals, castration is commonly used for contraception. Other forms of male contraception are in various stages of research and development. These include methods like RISUG/VasalGel (which has completed a small phase II clinical trial in humans in India) and ultrasound (with results so far obtained in experimental animals). Vasectomy is a surgical procedure for male sterilization or permanent birth control. During the procedure, the vasa deferentia of a man are severed, and then tied or sealed in a manner such to prevent sperm from entering into the seminal stream (ejaculate). Vasectomies are usually performed in a physicians office or medical clinic. CDC research has estimated there is a probability of 11 failures per 1,000 procedures ...

Adjudin was derived from the anti-cancer drug lonidamine. Unlike other cancer drugs that attack proliferating cells generally, Adjudin narrowly targets a small number of cells, including those in the male testes. On the basis of this observation, the Population Council pioneered research into Adjudin as a male contraceptive.. Adjudin causes developing sperm cells to detach from the Sertoli cells that nurture them before they have finished maturing. The prematurely detached cells die, causing temporary infertility. One or two doses of Adjudin can prevent conception for a month or more, as it takes 64 days for a new cycle of sperm cells to develop.. Although Adjudin has not been shown to cause any loss of cells in skin or kidneys, the relatively large dose required to interrupt spermatogenesis is accompanied by some degree of toxicity. The margin between safety and efficacy is narrow. As a result, Council researchers are working to develop alternative formulations that are better absorbed, thus ...

Makes more sense, but still, I disagree. But lets talk about birth control.. Modern birth control for women is possibly the most important invention of the last century, and Im very grateful for it. Its also brutal. The side effects for many women include migraines, mood swings, decreased libido, depression, severe cramps, heavy bleeding, aneurysm - and thats just a small fraction of them.. Discouragingly, a promising study on a new male contraceptive was canceled in large part due to… (wait for it)… side effects. To be clear, this list of side effects was about one-third as long as the known side effects for commonly used womens contraception. Theres a lot to unpack in that story alone. Ill simply point out that, as a society, we really dont mind if women suffer, physically or mentally, as long as it makes things easier for men.. But, men, Ive got good news. Even with the horrible side effects, women are (amazingly!) very willing to use birth control. Unfortunately, its harder to ...
Geneticists say that we should not yet add the male to the endangered species list, and for now all is not lost for the little modern Y. It was previously thought that the Y chromosome contained mostly junk DNA and that the production of the testes triggered by SRY was its only function. But it is now known that the genes remaining on the Y chromosome are particularly important for survival in males and for fertility. In about half of all couples affected by infertility the problem rests with the man. Disruption of the genes on Y can reduce sperm count causing infertility. Infertility research is now directing efforts towards understanding the strange Y and searching for a cure. On the flip side, the possibility of new male contraceptives that target the sperm producing regions of Y is being developed ...

An experimental male contraceptive method involves heating the testicles so that they cannot produce sperm. Sperm are best produced at a temperature slightly below body temperature. The muscles around a males scrotum involuntarily tighten if the mans body temperature drops, and they loosen, allowing the testes to hang, if the body temperature rises. This is the bodys way of keeping the sperm at an ideal temperature.[citation needed] Although research has not addressed methods of applying heat, sperm production can be disrupted with increased temperature. Some suggest exposure to high temperatures (116 °F) can affect fertility for months. Methods used include hot water applied to the scrotum, heat generated by ultrasound, and artificial cryptorchidism (holding the testicles inside the abdomen) using specialized briefs. One of the initial experiments resulted in partial infertility lasting more than four years. Initial experiments suggest it is effective and safe, though there have not been ...
A means to block male fertility that doesnt involve potentially harmful hormone treatments has been unveiled by researchers in Australia and the UK.A male equivalent of the female oral contraceptive pill has long been sought-after by scientists. But, so far, every attempt has failed, owing mainly to the risk of significant side-effects or concerns over long-term impacts on fertility.
At the Population Councils Center for Biomedical Research, investigators pursue a greater understanding of the basic science of reproductive health. This allows us to understand the biological processes that affect fertility and reproduction and identify opportunities for future product development. Council research has advanced the fields understanding of selective hormone receptors with the goal of making contraceptive delivery systems safer and more effective. Our research on the biology and regulation of sperm cell activities may help inform contraceptive development for men and increase understanding of the underlying causes of male infertility.. Additional research focuses on identifying sperm function to promote the development of non-hormonal contraceptive methods and to understand the effects of the environment on reproductive health.. ...
