Independent reference archive
Reproductive biology and fertility, decoded.
Between 1960 and 2023, this address served the journal Reproduction, formerly the Journal of Reproduction and Fertility, and its companion Reviews of Reproduction. The journal has moved to its publisher. The citations have not: tens of thousands of papers, textbooks and web pages still point here.
So this site does two things. It keeps a reference record for every one of the 13,309 articles at the address the journal used, with the citation and a link to the publisher's full text. And it publishes plain-language articles on fertility and reproductive health, written for readers rather than specialists, with the research cited.

How common is infertility? What the WHO and NHS figures actually say
One in six people experience infertility in their lifetime, according to the WHO. What that figure measures, how the NHS describes the odds of conceiving, and when to seek advice.
IVF add-ons: what the evidence shows, add-on by add-on
Endometrial scratching, time-lapse imaging, PGT-A, EmbryoGlue and more: the UK fertility regulator's five-colour ratings, explained in plain language.
From one birth in 1978 to millions: how IVF became routine
Louise Brown, the 2010 Nobel Prize, 13 to 17 million IVF babies and about four million treatment cycles a year: the history of IVF in verified figures.
Endometriosis explained: symptoms, diagnosis delays and treatment options
Endometriosis affects about 10% of women and girls of reproductive age, around 190 million people. What the WHO says about symptoms, the long road to diagnosis and treatment.
Are sperm counts really falling? What the evidence says
A 2022 meta-analysis found that average sperm concentration fell by about half between 1973 and 2018. What the study shows, what it does not, and what a 'normal' result means.
When does menopause happen? Average age, early menopause and what it means for fertility
The average age of menopause in the UK is 51. What counts as early menopause and premature ovarian insufficiency, how common they are, and how menopause relates to fertility.
Miscarriage explained: how common it is, the warning signs and what happens next

About this site
Who runs it, how the archive works, and why it is not the journal.
This domain hosted the journal Reproduction and its predecessors until the journal moved to its publisher's platform. This site is independent: it is not the journal, its publisher or its society. Reference pages are kept at the original addresses so that existing citations keep working; the full text is available from the publisher through the DOI.
