Early corpus luteum formation (corpus haemorrhagicum) in a 3--3/12-year-old "senile" mouse.
In a female mouse sacrificed at the age of 3--3/12 years, corpus heamorrhagicum and arteric corpora lutea were found in the ovaries, apart from smaller follicles. No evidence could be found in the literature for their presence at this age. Based on these findings, aspects of basic gerontological research are discussed.
