Dear Simon,

Seasons greetings.

Apologies for the delayed reply as I did not log on for a few days. You could use the Internetgrateful Med @ http://igm.nlm.nih.gov

You can create a temporary journal list and search only in J of Andrology (PA). I also found International Journal of Andrology in the list of journals. You can begin by using case control study as the title word (but there are no papers in J Andrology with the word case control study in title). Then you can use case control study as the subject word ( I found 8 papers in this journal).

This might work when you are searching few journals but the same may not apply if we are searching the whole MEDLINE as we might end up with lots & lots of papers.

Hope this is of some interest.

Cheers and warm regards,

Badri
