What is the truth behind Kourtney Kardashian's claims about IVF and menopause?

Kourtney Kardashian has claimed that fertility treatment pushed her into menopause.

The reality star revealed her experience with IVF in the 'trailer' of "The Kardashians".

The mother-of-three said she wants to have a child with rocker fiance Travis Barker.

The 42-year-old told mum Kris: "Everybody on social media is always like 'Kourtney's pregnant, Kourtney's pregnant, Kourtney's put on so much weight.' It's so rude to comment on people when you have no idea what they're really going through. The drugs they are giving me put me into menopause. Literally in menopause".

And a number of IVF experts dug in for The Sun the facts behind the claim. Thousands of babies around the globe were born using methods first pioneered in the 1970s.

The process involves removing eggs from a woman's ovaries and fertilizing them using sperm in a laboratory.

One or more fertilized eggs, known as embryos, are then transferred to the woman's womb to grow.

While we don't know Kourtney's medical history and the 42-year-old's specific experience, a number of experts told The Sun that IVF cannot cause menopause. Menopause naturally begins in your 40s or 50s, with the average age for most women between 45-55.

Adam Balen, a professor of Reproductive Medicine and Surgery, said: “When you do IVF, it's a short-term treatment and there's no evidence of any long-term effects. The data are very reassuring and there is no medical reason why IVF drugs would advance menopause."

Professor Luciano Nardo, an IVF expert, explained a drug used by some clinics to help with egg retrieval called GNRH, which can "put women into a pseudo menopausal state".

This gives the doctor more control over starting a new cycle, but because the menopause-type condition is only for a short time, it is "self-limited".

He added: “There is no evidence that by starting these GNRH injections your body will go into menopause. Some women are deprived of hormone production, so it is possible that some women may experience some menopausal symptoms. But there is definitely no evidence of a permanent effect of menopause." /Telegraph/
