United Kingdom[edit] In the UK, previous NICE guidelines defined infertility as failure to conceive after regular unprotected sexual intercourse for two years in the absence of known reproductive pathology.[11] Updated NICE guidelines do not include a specific definition, but recommend that "A woman of reproductive age who has not conceived after 1 year of unprotected vaginal sexual intercourse, in the absence of any known cause of infertility, should be offered further clinical assessment and investigation along with her partner, with earlier referral to a specialist if the woman is over 36 years of age."[12] Other definitions[edit] Researchers commonly base demographic studies on infertility prevalence on a five-year period.[13] Practical measurement problems, however, exist for any definition, because it is difficult to measure continuous exposure to the risk of pregnancy over a period of years.

Infectious, anatomic, metabolic, and functional problems associated with infertility are seen less frequently. (Also see Infertility.) The only confirmed infectious cause of infertility in the bitch is brucellosis (see Brucellosis in Dogs). For a woman to conceive, certain things have to happen: vaginal intercourse must take place around the time when an egg is released from her ovary; the system that produces eggs has to be working at optimum levels; and her hormones must be balanced.[54] For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs.
