Female authorship share in top medical journals fails to improve

"“Unfortunately, the differences in women versus men [authorship outcomes] identified here may likely serve to perpetuate the current gender inequalities found throughout medicine.” They add that the causes for the disparities were likely complex and involved issues around the career pipeline for women in medicine and implicit gender bias at institutions." - Why is it "unfortunate"? This assumes that women and men's interest in medical research and talents are on average identical, but if it were not so, that might itself be one of the "causes for the disparities". Does empirical psychology suggest that men and women's minds are on average identical?
