This is a collection of the top ten Obstetrics and Gynaecology journals ranked by their Impact Factor as reported by Journal Citation Reports (JCR). JCR is currently published by Clarivate, a new corporation founded by Onex Corporation and Baring Private Equity Asia after they acquired Thomson ISI in 2018.

How do you calculate the Impact Factor (IF) for journals?

Impact factor was first designed by Eugene Garfield, the founder of the Institute for Scientific Information (ISI) in 1975. IF is a ratio between citations and recent citable items published by individual journals.

  • A = the number of total citations received by a Journal in (say) 2020.
  • B = the number of citations received by the Journal in 2020, but only to articles published in the previous 2 years (2018-2019); hence, B is a subset of A.
  • C = the number of articles published by the journal in the previous 2 years (2018-2019).
  • D = B/C = the IF of the Journal for 2020.

There are 82 Obstetrics and Gynaecology journals categorised by JCR in 2020. The top 10 are listed below:

Impact Factor 2019 for Obstetrics and Gynaecology journals
Impact Factor 2019 for Obstetrics and Gynaecology journals

Just to put this in perspective, 2019 IF for top journals related to medicine and health are: CA-Cancer J. Clin. (IF 292.2!), N. Engl. J. Med. (IF 74.6), Nat. Rev. Drug Discov. (IF 64.7), Lancet (IF 60.3), Nat. Rev. Mol. Cell Biol. (IF 55.4).
