Lying with your legs in the air after sex has long been claimed to boost the chances of getting pregnant.
But a £49 sperm-catching device may spell the end of the decades-old conception ‘hack’ — which experts say never worked anyway.
A couple who spent half a year unsuccessfully trying for a second baby say they fell pregnant after using the silicone contraption just once. Kate Bennison, 36, is now four months pregnant with her husband Mark.
Women put the product into their vagina — like they would with a tampon — before sex, and their partner’s penis slides over it.
Once the man ejaculates and withdraws, a flap in the device springs up and forms a seal to stop semen from escaping. This directs more sperm straight to the cervix and keeps them their for longer — up to an hour.
Ms Bennison, from Redcar in Yorkshire, told MailOnline: ‘I was worried it would be really uncomfortable and I’d be stuck lying down.
‘But because it’s so soft, once inserted you really don’t notice it.’
She added: ‘Previously when trying to conceive I did the unromantic “legs up after sex”.
‘However with this in you can just cuddle up with your partner safe in the knowledge it’s not going anywhere.’

The couple experienced fertility issues when trying to conceive their first daughter, Grace, who is now two.
They had several miscarriages and took three years to get pregnant.
So how DOES the £49 fertility device work?
The twoplus sperm guide is a device designed to minimise leakage of semen post-intercourse.
Women insert it into the vagina and have their partner’s penis glide over it (and into the vagina) to begin intercourse.
Upon insertion, users should be able to see the sperm guide’s tail in plain view outside the vagina.
The silicone device sits right beneath the deeper region of the vaginal tract, allowing semen to interact directly with the cervical mucus, creating a ‘highway’ for sperms to swim to the egg and increases chances of fertilisation.
Once the man withdraws, a flap springs up which forms a seal and stops semen from coming out.
Twoplus Fertility, which makes the device, advises keeping it in for around one hour after sex.
It says the device can be used up to four times.
After trying for six months for a second, the couple resorted to the twoplus ‘Sperm Guide’ to increase their chance of conceiving.
They became pregnant after using the sperm guide once, but went on to suffer an early miscarriage.
They used the device, which launched in the UK last year, twice more and became pregnant on the third attempt.
Around one in seven couples in the UK have problems conceiving, but 84 per cent conceive naturally within a year of trying if they have unprotected sex every two to three days.
Ms Bennison said she didn’t notice the sperm guide after it had been inserted and it ‘keeps the romance there after sex’.
Along with using the sperm guide, Ms Bennison stopped drinking alcohol and took some prenatal vitamins.
Twoplus recommends women keep the reusable contraption — which can be gently pulled out by its ‘tail — in place for an hour after sex.
It also insists the device won’t get in the way because it’s ‘springy’ sperm flap allows the penis to ‘effortlessly glide over’.
‘After ejaculation, the male withdraws and the twoplus flap springs up,’ the firm says on its website. ‘This forms a seal that blocks the back-flow of semen.’
Men release 100million sperm on average when they ejaculate but a tiny amount of that reaches the uterus.
The sperm guide creates a ‘highway’ for the sperm to swim to the egg.
Recalling their experience with the device, Ms Bennison said: ‘We didn’t experience any leakage during or after sex.
‘I would recommend that anyone trying to conceive without success give the sperm guide a chance. It has literally helped us complete our family.’
Dr Benjamin Tee, founder of twoplus, said: ‘We are super delighted our technology helped Kate and her husband conceive as soon as possible.
‘We hope to continue bringing our science-backed innovations to the hands of couples so they can experience the indescribable joy of parenthood.’
