Menopause is a natural phenomenon that occurs when the ovaries stop functioning (i.e. no longer produce eggs and thus estrogen and progesterone hormones). A main symptom is that the woman's menstrual cycle will stop; hence the name: 'menopause' [menstruation pause]. It's a perfectly natural process so nothing to worry about.
A milestone is defined as a significant stage or event in the development of something. NG23 is not a milestone document but another millstone around the neck of a profession that is trying to maintain the trust that patients have in it.. NICE needs to choose its words carefully. A 'sound bite' can often bite you back.
They may be not perfect, but condoms are currently the only way to stem the tide. Once older couples are in a monogamous relationship, they can have a joint sexual health screening at a genitourinary clinic and if the results are clear they can ditch the condoms, because an infection can only be contracted if there is one present.
