In the UK, the National Health Service (NHS) is considering new plans that could prevent smokers and vapers from accessing IVF treatment. The proposed policy is part of wider efforts to improve the success rates of fertility treatments and the health of babies born through IVF. Researchers have found that smoking can reduce fertility and increase the risk of miscarriage, while vaping is still not fully understood in relation to fertility and pregnancy. The potential ban has sparked debate, with some arguing that it could be seen as discriminatory. There is also concern that such a ban could lead some women to lie about their smoking or vaping habits. The decision about the implementation of this policy ultimately lies with individual Clinical Commissioning Groups.
