When it involves having intercourse, there are nuggets of so-called knowledge most of take as gospel. Those with dodgy hearts or dangerous backs for instance, ought to keep away from intercourse or take it straightforward, ladies on their interval can’t get pregnant and peeing beforehand may cut back the chance of a urinary tract an infection. As it seems, most such nuggets are nothing however myths.
#1 Having intercourse will increase your possibilities of a coronary heart assault: MYTH (…besides for those who’re dishonest)
Heart assault sufferers are sometimes apprehensive about getting busy between the sheets however a paper printed final week within the Journal of the American College of Cardiology suggests they needn’t fear.
Researchers regarded on the well being histories of 536 coronary heart illness sufferers aged 30 to 70 and located that sexual exercise was not a danger think about any subsequent coronary heart assaults.
Just .7 of sufferers reported having intercourse inside an hour earlier than having a coronary heart assault whereas 78 per cent mentioned that they had intercourse greater than 24 hours earlier than the center assault.
‘Based on our data, it seems unlikely that sexual activity is a relevant trigger for heart attack,’ mentioned Deitrich Rothenbacher, lead writer of the examine and professor and chair of the Institute of Epidemiology and Medical Biometry at Ulm University, Germany. ‘Patients need not be worried and should resume their usual sexual activity.’
Someone will occur to have a coronary heart assault similtaneously they’re having sexual activity and people are the circumstances we hear about, says Dr Mark Knapton, affiliate medical director of the British Heart Foundation. ‘But they were going to have a heart attack anyway, it’s not the intercourse that did it.’
‘What’s extra worrying is when sufferers expertise erectile dysfunction as that is typically an indication of an underlying coronary heart downside,’ added Dr Knapton.
The similar guidelines don’t apply if to the adulterous, nonetheless.
A paper printed in 2012 in The Journal of Sexual Medicine discovered males have been extra more likely to expertise ‘sudden coital death’ – a deadly coronary heart assault throughout intercourse – throughout intercourse with somebody aside from their wives.
‘Sex causes arousal, excitement, stimulation of the adrenal glands,’ says Dr Knapton, including that these results could also be heightened with a brand new associate.
‘It’s a bit like the joy of watching a soccer match, which has additionally been reported to result in elevated numbers of calls to well being emergency companies due to cardiac issues.
‘Of course, we would advise waiting 4-6 weeks after your heart attack before resuming sexual activity, but after that, sex generally won’t trigger an elevated danger of coronary heart assault.’
Those with vital coronary heart failure, harm to their coronary heart muscle or a historical past of extreme angina may expertise breathlessness that would restrict their sexual exercise, and may discuss to their medical doctors.
Sexual exercise can in actual fact, depend as a necessary a part of the 30 minutes a day train regime of coronary heart assault sufferers, Dr Knapton advises. But provided that it lasts that lengthy – which is unlikely, he says.
Indeed, a paper printed in January 2013 within the New England Journal of Medicine examined the physique of proof for the declare that intercourse is nice train and concluded that the typical bout of sexual exercise was solely six minutes and expended a paltry 21 energy.
#2 If you stand in your head after intercourse it will increase your possibilities of getting pregnant: MYTH
In truth, mendacity down as an alternative is simpler at growing your possibilities of being pregnant.
A randomised managed trial printed within the British Medical Journal in 2009 checked out 400 who have been being artificially inseminated and located that the ladies that lay flat for 15 minutes had a 50 per cent better likelihood of getting pregnant than people who instantly acquired up and walked round.
The similar might maintain true when involves getting pregnant after having intercourse, says Dr Gabrielle Downey, advisor gynaecologist and obstetrician at BMI Hospital, The Priory in Birmingham.
But whereas there’s completely no want to face in your head, you possibly can assist the method alongside.
‘A woman’s uterus is bent barely forwards so for those who tilt your pelvis upward a bit, say by placing a pillow below your decrease again as you lie down, the sperm can have much less of a distance to journey,’ says Dr Downey.
‘That means they are effectively travelling downhill and need less energy to get to where they want to go.’
But why 15 minutes? Post-sex sperm need to get into the womb, journey throughout it and thru the fallopian tubes, she explains.
‘I would actually suggest that lying down for half an hour after sex would be better, to ensure this process has enough time to happen,’ advises Dr Downey.
After that, gravity isn’t fairly so vital to sperm’s actions because the fallopian tubes have rhythmical actions inside them that assist the motion of sperm alongside, she explains.
#3 You can’t get pregnant in your interval: MYTH
There is not any time at which a girl between the ages of 15 and 50 can’t get pregnant, says Dr Gillian Lockwood, advisor obstetrician and gynaecologist and medical director of Midland’s Fertility Services.
Ideally, the window of alternative for implantation when conception can happen, is a quick 3 to 4 day time which happens spherical about cycle days 18 or 19, taking cycle day 1 as the primary day of the interval, she says.
But an excellent egg launched throughout ovulation has a life span of presumably about 4 or 5 days days and wholesome sperm have fertilising capability for as much as 4 days, she asserts.
‘This is why we hear about lots of women who’ve thought, ‘Oh, it’s the tail finish of my interval. I’m completely protected”, however really, they get pregnant.’
Furthermore, in response to Dr Gabrielle Downey, post-pregnancy you may be at elevated danger.
During being pregnant, all of your hormone ranges are excessive typically, besides those that stimulate your ovaries to make eggs are low, she explains. But this adjustments.
‘After you have had the baby, the brain tries to stimulate the ovaries again to make eggs so it can induce another pregnancy, so it sends out strong hormonal signals to the eggs to say ‘Right. Start working,’’ she says.
‘The effect is so strong that it’s virtually like having fertility therapy so don’t use having your interval as contraception.’
#4 Headaches are an excellent excuse to not indulge: MYTH (…and intercourse may assist)
In ladies, orgasm may really assist the ache of a headache cancelling out the age-old ‘Not tonight darling…’ excuse.
In truth, in analysis printed in 2013, a crew of neurologists from the University of Munster, Germany discovered that over half of of migraine victims who had intercourse throughout an episode skilled an enchancment in signs.
Staggeringly, one among 5 completed with no ache in any respect – a distinction seen in male victims particularly.
The researchers theorised that intercourse triggered the discharge of endorphins, the physique’s pure painkillers, by means of the central nervous system, which may cut back or eradicate a headache.
Indeed, in response to Dr Beverley Whipple, the neurophysicist from Rutgers Universitywho found the G-spot within the late 70s (on the entrance wall of the vagina, 5cm from the doorway), having this space stimulated to orgasm elevated ladies’s ache threshold by 106 per cent.
#5 People with dangerous backs ought to keep away from strenuous intercourse: MYTH
A staggering 4 out of 5 folks expertise at the least 1 episode of debilitating low again ache of their lifetimes and as much as 84 per cent of males and 73 per cent of girls with the situation report a lower within the frequency of intercourse.
But analysis printed in October final 12 months within the journal Spine discovered that sure positions may make intercourse much less painful for victims – relying on the kind of again ache you will have.
Women who get low again ache after they arch their backs or lie on their stomachs skilled much less ache within the missionary place, the researchers discovered.
For males with again ache (particularly if it damage after they touched their toes or sat for too lengthy), doggy fashion was the most effective place and adopting a ‘hip-hinging motion instead of thrusting with their spines’ may additionally reduce the ache.
According to physiotherapist Tim Allardyce of Surrey Physio, doggy fashion is certainly an excellent place for low again ache in males – with 1 caveat.
‘They have to ensure they are on their knees rather than standing up,’ he explains.
‘One of the biggest causes of pain for lower back pain sufferers or those with slipped discs is forward bending,’ he says.
‘By kneeling the back remains in a safe position, maintaining its natural curve which will minimise the pain during sex.’
If the person is standing however (with the girl on all fours on the mattress) he’ll typically need to bend his knees a bit, spherical his again and lean ahead to get the suitable angle, Allardyce says. This can improve low again ache or pressure an present damage.
He agrees that the missionary is nice for girls with decrease again ache because it retains her backbone on impartial, that’s, in a slight S-shaped from the decrease to higher backbone, thus minimising ache or additional damage.
Kneeling throughout doggy fashion or lady on prime might also work for girls – so long as she doesn’t arch her again an excessive amount of.
‘The main thing is to keep that natural curve in the spine and not round or arch.’
What ladies ought to keep away from is bending absolutely forwards with the person behind them, as this places an excessive amount of pressure on the decrease discs of the backbone and will result in damage, says Allardyce.
While there’s no motive these with again ache must keep away from having intercourse, some issues are simply asking for hassle, he asserts.
‘When people start doing like having sex over sofas or in cars and showers, they often need to get their bodies into tight, complicated environments and find themselves aggravating an existing back problem or creating a whole new one,’ he warns.
So what’s essentially the most back-unfriendly intercourse transfer? ‘Definitely a man trying to pick someone up – literally – against a wall, in the shower or into mid-air,’ says Allardyce.
#6 If you pee earlier than intercourse you cut back your possibilities of an STI: MYTH
Around half of of all ladies and 1 in 2000 males will develop a urinary tract an infection (UTI) annually, in response to the NHS.
UTIs develop when the bladder turns into contaminated, normally by micro organism which mostly enter by means of the urethra.
Sex is a typical reason behind UTIs in younger ladies of their 20s, says Dr Zaki Almallah, advisor urologist at BMI Hospital in Edgbaston.
But it additionally impacts older ladies. One examine in 2008 printed within the Journal of General Internal Medicine additionally discovered that sexual activity was additionally related to the chance of UTI in postmenopausal ladies too.
While most of us are informed to pee earlier than and after intercourse to keep away from UTIs, that is solely half of true, say specialists.
Indeed, in accordance 1 main New York urologist Dr David Kaufman, peeing earlier than intercourse ‘is the number one cause of post-coital urinary tract infections.’
According to Kaufman, UTIs may be brought on when throughout intercourse, micro organism can get pushed into the urethra. But not urinating earlier than intercourse means you should have sufficient saved within the bladder to create a robust stream, making it extra seemingly that micro organism might be flushed.
While Mr Almallah says there’s no actual proof for Dr Kaufman’s idea, he says there isn’t a must urinate earlier than intercourse for those who don’t must, as it’s going to don’t have any impact on stopping a post-intercourse UTI. But urinating afterwards might help.
Bacteria that trigger UTIs normally dwell naturally within the space referred to as the perineum – between the anus, vagina and urethra – and intercourse can transport micro organism from these areas into the bladder by means of the pipe of the urethra.
‘Urinating after sex means you’re flushing out any micro organism that has lodged throughout intercourse into the urethra, which is the supply of this transport of micro organism into the bladder, thus serving to minimise your possibilities of a post-sex UIT,’ Mr Almallah explains.
#7 Sex and orgasm can induce early labour: MYTH
Theoretically, intercourse can induce labour, however the cervix must be prepared, explains Dr Downey. Semen accommodates hormones referred to as prostaglandins (which come from the person’s prostate gland) which may soften the cervix and stimulate contractions.
Synthetic types of these are used medically to induce labour, which is why – theoretically – it’s doable that intercourse might hasten labour. But provided that you’re near your due date.
‘Your cervix has to ripen and be receptive to prostaglandins and this only happens near the end of your pregnancy,’ Dr Downey says. ‘If your cervix isn’t prepared, having intercourse at 20 weeks gained’t make you go into early labour.’
Having mentioned that, intercourse might induce Braxton Hicks contractions, attributable to the ache from tightening of the uterine muscle tissue felt typically within the 2d or 3rd trimester and generally mistaken for labour pains.
‘Anything that stimulates movement in the uterus can cause Braxton Hicks – including sex – but the difference will be that they tend to only last 20-30 seconds and will rarely stop you from doing what you’re doing, which is a inform story signal you’re in labour’.
Plus, actual labour pains begin and get progressively worse and extra frequent, whereas Braxton Hicks are usually short-lived, she explains.
There are caveats nonetheless.
If your midwife or advisor have mentioned your membranes have ruptured (when a tear develops within the fluid-filled bag that surrounds the child), when you’ve got low-lying placenta (normally detectable at your 20 week scan), if you’re having twins, are at elevated danger of an infection or anticipating a untimely child, chances are you’ll be suggested to keep away from intercourse throughout half or all of you being pregnant, Dr Downey explains.
