Ovariectomy

From 2021 to 2025, 309 animal research papers mentioned ovariectomy and at least one behavioral test.

That is about the same as the 322 papers of 2011 to 2015. Between the same two periods, all the animal research papers that mention any of the 90 tests we count rose 22%. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.

309 animal research papers from 2021 to 2025 mentioned ovariectomy and a test
About the same number of papers as in 2011 to 2015
18% of these papers mention the forced swim test
8% of the 3,775 animal research papers from 2021 to 2025 that mention ovariectomy also mention a test

The tests mentioned with ovariectomy

Treadmill running appears in 13% of these papers and in 6.5% of all 32,277 papers that mention a test. That makes it 2.0 times as common in this research. Each bar is one test, with how many of the 309 papers from 2021 to 2025 mention it, and what share that is. A paper that mentions two tests counts under both.

Papers that mention ovariectomy and a test fell from 78 in 2021 to 50 in 2023, then rose to 62 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. We take a paper's species from PubMed's indexing when the indexing names one. Otherwise PubTator 3, NCBI's text-mining service, has to find a species in the title or abstract, or the paper is not counted. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.

Disease models in papers that mention ovariectomy

Each bar is one disease model, with how many of the 309 papers from 2021 to 2025 are tagged with it, and what share that is. The model comes from the paper's MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. A paper without MeSH terms gets its model from PubTator 3, NCBI's text-mining service, if PubTator 3 finds the disease in the title or abstract. A paper can count under more than one model.

Which species the papers used

Each bar is a share of the 309 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

โ€œOther animalsโ€ counts papers that use none of the species this chart names.

NIH funding

54 of the 309 papers (17%) had NIH funding. NIA, the National Institute on Aging, funded the most, 17 of them. A paper counts as NIH-funded when its PubMed record lists an NIH grant, or when NIH RePORTER links it to an NIH project.

How we counted

A paper counts here when it is animal research and its title or abstract mentions ovariectomy and at least one of the 90 behavioral tests. A count is a number of papers, not of experiments, labs or animals. A paper that mentions ovariectomy only in its methods is missed, so the count runs low.

A paper is animal research when its MeSH terms name an animal species. If they name none, NCBI's text-mining service PubTator 3 has to find one in the title or abstract. Papers on animals other than mice, rats, zebrafish, flies and primates count only when they also mention a test. Many of them study people or use the same words for something else.

The search terms for ovariectomy are in the download Animal models and brain techniques. The counts in the chart of tests are in Tests mentioned with each model or technique. The full method, with each source and its terms of use, is on our main page, Behavioral tests in published research.

More animal models

Each animal model with 100 or more papers from 2021 to 2025 that mention a test has a page. These are the others, each with that count.
