Curious about male contraception? We’re in the business of helping people have children, but not everyone who wants kids has baby-making on their mind right now. Lots of people may be sure they want kids in the future, but aren’t ready at their current stage in life – and that’s where contraception comes in. 

Whilst there are a tonne of options of birth control for women, there aren’t many male contraceptives out there right now, but the future looks bright! Here we’ll run through current methods, exciting prospects on the rise, and how these may impact fertility.

What are current male contraception options?

Condoms

The classic contraception. Condoms (well, specifically male condoms) are sleeves that go over the penis to prevent mixing sexual fluids. They’re typically made of very thin latex, but there are also plastic and lambskin alternatives for people with latex allergies.

Pros:

  • condoms prevent both STIs and unwanted pregnancy
  • condoms are easily available in most supermarkets or pharmacies
  • you can also get condoms free in most sexual health clinics, LGBT centres and some GP surgeries
  • condoms have no biological impacts on the wearer or partner

Cons:

  • condoms are not always effective, and many people like to use them alongside another form of birth control (like the hormonal pill) for added security 
  • they can’t be used with oil based lubricants such as vaseline or coconut oil as these will dissolve the condom
  • when used incorrectly, condoms can break

If there’s anything we’ve learnt from 90s TV, it’s that condoms don’t always protect from accidental pregnancy. Even when used perfectly condoms are only 98% effective. Which means 2 in 100 couples using condoms correctly will get pregnant over time. One aspect of this is that people aren’t perfect. Condom effectiveness can be impacted by human error – think putting them on incorrectly (even forgetting to put them on), or ripping them as you put them on – and problems with the condoms, such as ripping during intercourse.  

Natural contraception 

Natural contraception is just strategic sex to try and avoid getting pregnant. One of the methods is  the infamous ‘pull-out’ method . Which is when a male takes their penis out before ejaculating, so sperm doesn’t get inside. However, we do not recommend this method, as you can release sperm cells before ejaculation. Natural conception has become big again after the launch of Natural Cycles, which instructs the woman on how to track their fertile window. Unprotected intercourse can then be done during the non-fertile window, which is actually around 21 days per cycle (An average cycle is 28 days).  This method is also described by the NHS as the  Fertility Awareness Method (FAM), which involves timing sex around the fertile window and only having sex when your partner is not ovulating.

Pros of pull-out method:

  • it’s free and convenient
  • requires no medication or medical procedures
  • some people report that they don’t like the feel of condoms

Cons of pull-out method:

Pros of FAM:

  • natural family planning can be up to 99% effective when followed perfectly
  • requires no medication or medical procedures
  • most faiths and cultures allow for this form of contraception

Cons of FAM:

  • it doesn’t prevent STIs such as HIV, gonorrhoea, chlamydia
  • it requires abstinence or using condoms during fertile windows
  • not everyone has predictable or reliable menstrual cycles, which can lead to unexpected pregnancies
  • It takes time to properly establish your partners fertile and non-fertile days.

So while it’s better than nothing, couples should only use natural conception after they have made their  STI screenings. The efficacy of natural contraception depends heavily on the compliance to your partner’s fertile window. If she does have her fertile window or her cycle starts to be irregular it is better to use a condom during those times to be safe, if you’re not ready for kids right now.  

Vasectomy 

A vasectomy is a surgical procedure to cut or seal the tubes that carry sperm. This makes it (almost) impossible to impregnate a partner. It’s a quick procedure done under local anaesthetic – meaning you’re awake for the surgery – and takes around 15 minutes.

Pros:

  • it’s more than 99% effective
  • It’s a one-off procedure, meaning you don’t have to worry about contraception
  • Your hormone levels are left unaffected, so your mood, sex drive and erections will be left unscathed

Cons:

  • It comes with all the difficulties of surgery – pain, lack of movement during recovery, risk of infection
  • A vasectomy does not stop you from catching or giving STIs, so protection is still necessary in many cases
  • While vasectomies are reversible, the reverse surgery is very difficult and not always successful.

Ultimately vasectomies are for people who are 100% done with their baby-making. They’re a bit more permanent than most forms of contraception, and really aren’t ideal for anyone who just isn’t ready to be a parent now.

What does the future look like for male contraception? 

Since the current state of male contraception isn’t the most effective, women usually carries the burden of extra contraception. This is often with birth control pills, coils and implants, and all the side effects that come with them. But since sperm is the thing that actually causes the pregnancy (and the fact that there’s no shortage of it), then it makes a lot more sense to focus on male contraception. Sort of like putting a cap on a bottle of ketchup instead of wearing a plastic sheet over your white clothes.

Why is it taking so long for male contraceptives to become available?

It’s been more than 60 years since female contraceptives became publicly available, and yet research into male contraceptives has only taken off in the last few years. And even with so many breakthroughs, there are still no male hormonal contraceptives available.

A lot of this is down to the side effects of lowered testosterone. Many male contraceptives in the works come with the guarantee of zero side effects – the big ones being weight gain, developing acne and lowered sex drive. On the flip side female contraceptives have all of these side effects, and more. At this point many women are still waiting for a side-effect free contraceptive, while male contraceptives won’t be released until they’re reliably free of side-effects.

Right now, there are no male contraceptives available (apart from condoms). So let’s look at the options currently in the works.

The Male Contraceptive Pill 

What if men could take a contraception pill? Estrogen/progesterone birth control – or ‘The Pill’ – is one of the most common contraceptive methods, and is also used to manage painful or irregular menstruation. For many people however, the pill causes many uncomfortable, painful and even life threatening side effects. And with no reliable male contraceptive, the burden of these symptoms lies on women. The female pill has been around since the 1960s, so why is there still no male version?

According to YouGov, one in three (33%) of sexually active men are open to taking hormonal contraception. This is also the percentage of British women already using hormonal contraception, so it’s a significant amount. 8 in 10 of those taking the survey also said that contraception should be the responsibility of both partners, not just the man or woman. The attitudes towards a male pill are therefore pretty positive from both men and women.

Research into a male contraceptive pill has rocketed in the last few years, and with new funding from the Bill and Melinda Gates foundation, development and clinical trials may only be a few years away.

However, According to Professor Barratt at Dundee University’s School of Medicine, male hormonal contraception is more difficult to get around than female. “Men produce 1000 sperm in a heartbeat, so they’re producing more than 100 million sperm every day, and they do that continuously, 24/7.” An affective and reliable pill will need to stop that entirely, without impacting hormone levels severely or causing erectile dysfunction (after all, there’s no need for contraception if you can’t have sex). The trials have shown a lot of other side effects which delays further development, but these are the same side effects that female contraceptives have had for 60 years.

Heat Contraception 

You may have read our blog: Temperatura testicular: Cómo influye el calor en la fertilidad. But what if this could work as contraception? That doesn’t mean you should take a hair dryer to your balls, but there may be some exciting solutions on the horizon.

The way heat contraceptives could work is with nanoparticles injected into the bloodstream which are then moved and heated by magnets. The nanoparticles would heat up male testicles to prevent sperm production and kill any sperm. In their experiment, researchers injected citric-acid coated nanoparticles into the bloodstream of rats, guided the particles to the testes with magnets, then applied an alternating magnetic field for 15 minutes. This heated the testes to 104°F (40°C), stopping the production of sperm.

For 7 days the mice could have sex but not get any female mouse pregnant. In humans, sperm fully regenerates every 70 or so days. It’s similar for mice, and within 30 to 60 days after the experiment they recovered their normal sperm counts. 

Now this is a pretty innovative idea. The prospect of being injected with nanoparticles for days before sex also isn’t the most appealing, but it’s breakthroughs like this that can lead to more suitable solutions.

Gels

Once again one of the big barriers to figuring out male hormonal contraception is balancing a reduction in sperm and maintaining normal testosterone levels. And Nestorone/Testosterone gel may be the ticket.

Testosterone gel is already widely used by men who need to up their T levels. It’s a gel to apply daily into the shoulders. The gel absorbs into your system, giving you the hormone boost you need without any injection. Segesterone acetate (Nestorone) suppresses sperm production. The contraceptive gel will contain Nestorone to keep your sperm count low and Testosterone to keep hormone levels high.

Outlook 

Timing is everything when it comes to starting a family, which means contraception can be vital for those who want kids in the future. Not just in preventing surprise pregnancies, but also preventing STIs. Some of the most common STIs can harm your chances of conceiving. You can read all about it in our blog “STIs and Male Fertility – Is There A Link?”

And finally for guys hoping to be dads in the future, it’s never too early to check your sperm quality. It’s easy to assume that when the time comes, it’ll be all-too easy to make a baby. But that’s not always the case. With an ExSeed kit you can test your sperm count and quality from home, and get detailed information and advice about your results. You can put to bed any concerns and get some reassurance for the future. Or if your results aren’t so great, you have plenty of time to make a big difference to your sperm.

Finding out about your swimmers is one of the best ways you can plan for fatherhood, and give you a head-start on trying to conceive.

Guía sobre endometriosis y fertilidad

La endometriosis es una enfermedad que afecta a 1 de cada 10 mujeres y personas con menstruación, pero a menudo se diagnostica erróneamente y se malinterpreta. Aunque muchas mujeres con endometriosis pueden concebir de forma natural, existe la posibilidad de que la enfermedad afecte a la fertilidad.

Llevar pantalones y ropa interior ajustados

Los estudios demuestran que los hombres que llevan ropa interior más holgada tienen una mayor concentración de espermatozoides y un mayor recuento total de espermatozoides en comparación con los hombres que llevan ropa interior más ajustada. Así que deja la ropa ajustada y ponte algo holgado para dar aire a tus testículos.

CONCLUSIÓN: más información sobre cómo el calor puede afectar a la calidad del esperma aquí.

Estrés

Además de una mayor tasa de mortalidad y diversas enfermedades, el estrés se asocia a una baja calidad del esperma. Se sabe que el estrés está asociado a niveles más bajos de testosterona y al estrés oxidativo, desempeñando ambos un papel esencial en la producción y el mantenimiento de espermatozoides sanos.

CONCLUSIÓN: Si te sientes estresado, te recomendamos que busques ayuda para tener una salud mental equilibrada. Para obtener una guía de gestión del estrés, descárguese el ExSeed gratis y empieza hoy mismo tu plan de acción personalizado.

Actividad física

Los estudios científicos demuestran que los hombres físicamente activos tienen mejores parámetros seminales que los inactivos. Los especialistas en fertilidad también afirman que la actividad física regular tiene efectos beneficiosos sobre los parámetros de fertilidad del esperma y que un estilo de vida de este tipo puede mejorar el estado de fertilidad de los hombres.

Dar prioridad al ejercicio puede ayudar a mejorar su salud general y dar lugar a espermatozoides sanos y de natación rápida que tienen buenas posibilidades de fecundar un óvulo.

CONCLUSIÓN: Intente incorporar el ejercicio en su programa semanal para asegurarse de hacer ejercicio al menos dos veces por semana. Recomendamos una combinación de entrenamiento cardiovascular y ejercicio de fuerza. Más información ejercicio y fertilidad masculina en nuestro blog.

Nutrición

Comida rápida
Los alimentos procesados dañan la salud de las células productoras de esperma y provocan estrés oxidativo, lo que conduce a una peor calidad del esperma. El consumo excesivo de comida basura (todas las semanas) puede aumentar la probabilidad de infertilidad, ya que los hombres que consumen grandes cantidades de alimentos poco saludables corren el riesgo de tener una mala calidad del esperma. Además de perjudicar la fertilidad, la comida basura agranda la cintura, daña el sistema cardiovascular y los riñones, entre otras cosas.

Verduras
Comer más fruta y verdura puede aumentar la concentración y la motilidad de tus espermatozoides. Es importante que consuma una dieta sana llena de antioxidantes y que coma verduras todos los días. Alimentos como los albaricoques y los pimientos rojos tienen un alto contenido en vitamina A, que mejora la fertilidad masculina al nutrir un esperma más sano. Los hombres con carencias de esta vitamina tienden a tener espermatozoides lentos y perezosos.

Aperitivos/bebidas azucarados: varias veces a la semana El consumo excesivo de productos con alto contenido en azúcar puede provocar estrés oxidativo, que afecta negativamente a los niveles de testosterona y a la motilidad de los espermatozoides. Los tentempiés y bebidas azucarados también están muy relacionados con la obesidad y la baja fertilidad.
CONCLUSIÓN: Para mejorar la calidad del esperma, manténgase alejado de la comida rápida, los alimentos procesados y los aperitivos o bebidas azucarados. Debe seguir una dieta sana y prudente que contenga los superalimentos necesarios para una buena producción de esperma. Consulta nuestra guía sobre Superalimentos para la fertilidad masculina.

Calor

El calor directo puede inhibir la producción óptima de esperma y causar daños en el ADN espermático. A los espermatozoides les gustan los ambientes que están un par de grados por debajo de la temperatura corporal. Evite el sobrecalentamiento con mantas calientes, calentadores de asiento, calor de su ordenador portátil, duchas calientes y saunas.

Fumar cigarrillos

La exposición al humo del tabaco tiene importantes efectos negativos sobre la calidad del semen. El daño de los cigarrillos y la nicotina depende, por supuesto, de cuántos cigarrillos fume al día y durante cuánto tiempo, pero incluso un consumo bajo (hasta 10 cigarrillos / día) puede inhibir la producción de esperma sano.  

CONCLUSIÓN: Manténgase lo más alejado posible del consumo de cigarrillos si le preocupan su salud general y su fertilidad. Leer más aquí.

Teléfono móvil

Cuando llevas el móvil en el bolsillo delantero, tus testículos están expuestos a radiaciones electromagnéticas que, según los estudios, dañan los espermatozoides. Ponte el móvil en el bolsillo trasero del pantalón o en el bolsillo de la chaqueta.

IMC

Existe una clara relación entre la obesidad y la reducción de la calidad del esperma. Al menos en parte, esto se debe a que los hombres obesos pueden tener perfiles hormonales reproductivos anormales, lo que puede perjudicar la producción de esperma y provocar infertilidad. 

Un IMC superior a 30 puede provocar varios procesos en el organismo (sobrecalentamiento, aumento del estrés oxidativo en los testículos, daños en el ADN de los espermatozoides, disfunción eréctil) que pueden repercutir negativamente en la fertilidad masculina. Esto puede acarrear problemas a la hora de intentar concebir.  

CONCLUSIÓN: El IMC es uno de los factores de riesgo que influyen en la calidad del semen y, por ejemplo, en la movilidad de los espermatozoides.
