Spermicides and vaginal sponges are two over-the-counter birth control methods used during sex to prevent pregnancy. Trials had to focus on a spermicide used alone for birth control The product could be compared to a different spermicide, the same spermicide used with a barrier method, another dose of the same spermicide, a different base for the same product, or another type of birth control Each study must have had data on pregnancy. When Lisa Rentz decided she’d had enough of birth control pills, she walked into her local drug store and picked up something different: a vaginal contraceptive film that contains the spermicide nonoxynol-9, or N-9. Most contraceptive vaginal gels are surfactant-based spermicides that contain the active ingredient nonoxynol-9, which kills sperm by destroying the cell membrane. Up-to-date pricing and reviews for Contraceptive Gels on the market can be found at the many weeks pregnant website.
Until now, women who choose non-hormonal birth control had to deal with chemical laden spermicides or contraceptive gels that often led to rash or irritation. The remaining three trials are studying the effect of a drug on testosterone levels in the blood and/or sperm creation, effectively aiming to create a male birth control pill. “Nonoxynol-9 spermicide for prevention of vaginally acquired HIV and other sexually transmitted infections: systematic review and meta-analysis of randomised controlled trials including more than 5000 women”.
33 But a 2002 systemic review and meta-analysis of nine randomized controlled trials of vaginal nonoxynol-9 for HIV and STI prevention involving more than 5,000 women (predominantly sex workers) found no statistically significant reduction in risk of HIV and STIs, but found a small statistically significant increase in genital lesions among nonoxynol-9 spermicide users. Since the approval of the first birth control pill in 1960, other methods of contraception have been approved in Canada, including Norplant (1994 no longer available in Canada), female condoms (1996), depot medroxyprogesterone acetate (DMPA) injections (1997), progestin-only emergency contraception pills (1999), the levonorgestrel-releasing intrauterine system (LNG-IUS 20; 2000), the transdermal contraceptive patch (2002), the vaginal contraceptive ring (2004), extended-regimen oral contraceptives (2007), ulipristal acetate emergency contraception (UPA-EC; 2015), and the LNG-IUS 12 (2017). Despite this, the discontinuation rates for women participating in self-administration contraceptive methods such as spermicide averaged 44%, vaginal rings 32%; and female condom 49% at 6 months (personal communication with D. L. Blithe, Ph.D., NIH NICHD).
Sometime the gels used may cause irritation in vagina and cervix which may increase the rate of STD.Global contraceptive gels market is projected to grow rapidly due to increasing in awareness in sexual and reproductive health. Spermicides and vaginal sponges do not work as well at preventing pregnancy as some other forms of birth control. Vaginal douching is not considered a birth control method even if it is done with spermicides.
But hormonal birth controls like NES/T, the product Blithe and her colleagues are studying at NIH, are the male contraceptive products furthest along in clinical trials and appear to have the best shot at reaching the market most quickly. Over-the-counter vaginal contraceptive and spermicide drug products containing nonoxynol-9; Required labeling. If you get irritated using spermicide, you’re probably allergic to it. Unfortunately, all spermicides and contraceptive gels sold in the United States contain the same active ingredient, Nonoxynol-9.
Spermicides contain an active ingredient (most commonly nonoxynol-9) and a formulation used to disperse the product, such as foam or vaginal suppository. A gel containing nonoxynol-9 52.5 mg was inferior to two other products tested in the largest trial Aside from this finding, personal characteristics and behavior of users may be more important than characteristics of the spermicide products in determining the probability of pregnancy. Spermicides contain an active ingredient (usually nonoxynol-9) and something to disperse the product, such as foam or vaginal suppository (pessary).
The spermicidal action and adverse effects of other potential spermicides are also under study, including cellulose sulphate, LL-37, a human peptide called cathelicidin, a tampon-like biodegradable foam device, a vaginal gel that uses nano-sacs called polymersomes, vaginal tablets containing adhesive microcapsules, and subtilosin. As with female contraceptive trials with self-administration methods, nonadherence with daily gel application in some subjects may contribute to the lower spermatogenesis suppression rate as well as sperm rebound after suppression observed in this study. A pilot study using T and NES transdermal gels in healthy men for 20 d showed effective gonadotropin suppression without any significant adverse events ( 26 ), prompting us to evaluate this gel-gel combination for potential use as a male hormonal contraceptive.
VCF Vaginal Contraceptive Film® is a soft square of soluble film that dissolves, creating a gel coating that contains a highly effective spermicide that kills sperm on contact for up to 3 hours. “Expanding male contraceptive options could help make familyplanning more of a shared responsibility between women and men,”says Regine Sitruk-Ware, co-director of the trial, explaining theurgent need to develop an effective male contraceptive treatment.”Safe, effective, and reversible tools for men to control their ownfertility gives new meaning and significance to the term ‘familyplanning.’ No matter the challenge, we must continue to innovateand develop new products to improve lives.” Spermicides are not as effective as many other birth control methods , such as birth control pills or intrauterine devices (IUDs).
Spermicide may be a good birth control option for couples who can plan in advance of having sex and who want extra protection when they use condoms or other barrier methods of contraception. Spermicides can be used alone but are more effective when used with another birth control method , such as condoms or a diaphragm. The women in the trial will also use a form of female birth control for about the first four months their male partners are using the contraceptive gel.
Results from the trial are expected in 2022 and will help determine whether the NES/T gel should be evaluated in a separate, larger-scale Phase III contraceptive efficacy clinical trial, with the aim of obtaining approval from the U.S. Food and Drug Administration to market the product as a male contraceptive. Study participants were asked to engage in at least four acts of vaginal sexual intercourse per month, use the study product as the primary method of contraception, and keep a diary of coital activity, product use, use of other vaginal products, and adverse events. Contraceptive Efficacy, Acceptability, and Safety of C31G and Nonoxynol-9 Spermicidal Gels: A Randomized Controlled Trial.
Global contraceptive gels market is projected to grow rapidly due to increasing in awareness in sexual and reproductive health. Contraceptive gels are a form of chemical contraception which act as a birth control method. Health Canada warns that N9 in vaginal contraceptives and spermicides may irritate the lining of the vagina or rectum.
A product was approved by the U.S. Food and Drug Administration in August as part of a vaginal ring for women to use as birth control. When researchers conducted the first large-scale trial of female birth control in Puerto Rico in 1956, they didn’t seem to have such concerns about potential side effects (which at the time included nausea, dizziness, headaches, and blood clots ). Part of the reason that birth control went to market just four years later is the fact that for women “pregnancy is still a life-threatening condition,” Page said. Couples are being recruited to take part in a groundbreaking trial of a male contraceptive gel that could allow men and women to take equal responsibility for birth control in future.
A safe, highly effective and reversible method of male contraception would fill an important public health need,” study investigator Diana Blithe, PhD, chief of NICHD’s Contraceptive Development Program, said in a news release. This is because the success of male contraception depends on near complete suppression of sperm production while maintaining healthy testosterone levels to maintain a man’s sexual drive (libido). Contraceptive effectiveness and safety of five nonoxynol-9 spermicides: A randomized trial.
The U.S. Food and Drug Administration (FDA) warns that N9 in vaginal contraceptives and spermicides may irritate the lining of the vagina or rectum. Spermicides should be used with another barrier method of birth control such as a diaphragm , cervical cap , or condom You should take a pregnancy test if you are experiencing any pregnancy symptoms.

The road to market for Amphora, the Evofem gel, shows how long and winding it can be for contraceptives. About 20 years ago, Rush University’s labs in Chicago developed a version of the gel at a time of surging interest in products that could tackle both birth control and sexually transmitted diseases such as HIV. Since 2017, MCI has dispersed $1.7 million in funds from private donors toward global male contraceptive research, specifically to those studying non-hormonal birth control methods, which include methods that prevent sperm-egg interaction” and the development of new sperm, as well as those that block sperm from passing through the vas deferens. The past few decades of research have been able to correct for these problems: Hormonal contraceptives currently being tested for male use—gels, injections, and pills—typically use testosterone in conjunction with a second hormone or hormone compound to stop sperm production while regulating the testosterone levels in the rest of the body.
Research suggests there’s truth to Blithe’s theory: A recent survey from the Male Contraceptive Initiative found that 8.1 million men in the US are very likely” to use new male contraceptive methods, while 5.6 million are somewhat likely.” Another study published in the National Center for Biotechnology Information in 2002 found that 75 percent of male partners of women who had recently given birth would consider trying male hormonal contraception. This lengthy process isn’t exclusive to Blithe’s contraceptive gel: Other male birth control methods, like the pill and the injection , are making their way through this timeline, too, as any first-time drug would have to. On the phone earlier this month, Blithe described the steps it would take to get a contraceptive gel—the contraceptive product for men furthest along in clinical trials , and the one she’s currently studying at the National Institutes of Health (NIH)—to market.
Men might soon use this gel for birth controlThe National Institutes of Health recently funded a study to see if a topical gel for men could prevent pregnancy, potentially giving couples who don’t want children a new contraceptive option. Especially after the prohibition of contraception in the U.S. by the 1873 Comstock Act , spermicides—the most popular of which was Lysol —were marketed only as “feminine hygiene” products and were not held to any standard of effectiveness. Scholars K.T. Bartman and et al. study observing the distribution of spermicide containing Nonoxynol-9 in the vaginal tract, showed After 10 min the gel spread within the vaginal canal providing a contiguous covering of the epithelium of variable thickness.” 5 The sole goal of spermicide is to prevent fertilization.
In the largest trial to date, the gel (Advantage S) containing the lowest dose of nonoxynol-9 (52.5 mg) was significantly less effective in preventing pregnancy than were gels with higher doses of the same agent (100 mg and 150 mg). In August 2013, we searched the following computerized databases for randomized controlled trials of spermicides for contraception: CENTRAL, MEDLINE , POPLINE, LILACS, EMBASE , , and ICTRP. Gel was liked more than the film or vaginal suppository in the largest trial Spermicide trials have the dual challenges of difficult recruitment and high discontinuation rates; the latter threatens trial validity.
In August 2013, we did computer searches for randomized trials of spermicides used for birth control We have not found any new trials since the initial review For the initial review , we also wrote to researchers to find other trials. This is the first study of a transdermal male hormonal contraceptive regimen showing effective suppression of spermatogenesis using T gel combined with the nonandrogenic progestin NES gel. A recent 2-yr study using monthly T undecanoate injections in more than 1000 healthy Chinese men showed efficacy rates similar to female hormonal contraceptives ( 5 ). However, monthly injections are inconvenient and contraceptive regimens using T alone are not as effective in non-Asian men ( 8 , 10 , 11 ). Addition of progestins to exogenous T enhances the rate and extent of suppression of spermatogenesis in men of all races with few short-term side effects ( 11 – 24 ). Male hormonal contraceptive strategies to date have relied on combining injections, patches, or pellets of T (or its esters) with injectable, oral, or implants of progestins in two delivery forms.
The shots suppressed sperm production and prevented the men’s female partners from getting pregnant, but they also gave men severe mood swings and other serious side effects (see Why We Still Don’t Have Birth Control Drugs for Men” ). After more than a decade of work, government researchers in the U.S. are ready to test an unusual birth control method for men—a topical gel that could prevent the production of sperm. The product could be compared to a different spermicide, the same spermicide used with a barrier method, another dose of the same spermicide, a different base for the same product, or another type of birth control.
We did computer searches for randomized trials of spermicides used for birth control.

To study and analyze the global Contraceptive Gels market size (value and volume) by company, key regions, products and end user, breakdown data from 2013 to 2017, and forecast to 2025. When they look at male contraception, they see a global regulatory system that is largely unprepared to guide and support the study and approval of male contraceptive products. Pulling N-9 — the only spermicide available in the U.S. — off the market would effectively eliminate those few existing nonhormonal sources of birth control.
Spermicides are only about 78% effective in preventing pregnancy if used as the only form of contraception. Spermicides come in the form of creams, gels, film, or suppositories (an insertable solid dosage in either the anus or vagina), and often contain chemicals that are designed to kill sperm or otherwise reduce their motility in the vagina. This is the first serious, real-world test into a malecontraceptive for some time, and all members signing up for the trialmust be aware and willing to enter into a pregnancy if the gel provesineffective.

Finding a simple male contraceptive compound that is safe,effective and reversible has been relatively elusive for scientists.Outside of condoms and vasectomies, birth control has remained welland truly in hands of women. According to the Northern Arizona University site on vaginal spermicides, 2 applicators full are needed for women at elevations higher than 3500 feet Protection is immediate and lasts about an hour
