In this section, men and women over age 20 is being referred to
From Table A-1: https://www.bls.gov/news.release/empsit.t01.htm


September isn't at all typical of every recent month. But August and September were both months where 613,000 (Aug) and 649,000 (Sep) were the big months of male minus female differences in the labor force:

pp = percentage points.    LF = Labor Force,    LFPR = Labor Force Participation Rate

In August the male LF increased by 608,000 while the female LF decreased by 5,000 for a 613,000 differential

In September the male LF decreased by 216,000 and the female LF decreased by 865,000 for a 649,000 differential

From September 2019 to September 2020 (the past 12 months):
The male LFPR declined by 1.7 pp, while the female LFPR declined by 2.3 pp.
1,545,000 men left the LF while 2,463,000 women left the LF


From May 2020 to September 2020 (the past 5 months):
The male LFPR increased by 0.9 pp, while the female LFPR increased by 0.0 pp
1,239,00 men joined the LF, while 292,000 women joined the LF


As a reminder, the labor force statistics from the Household Survey (which is where these come from) are wildly volatile from month-to-month, with most of the month-to-month changes being more statistical noise than actual. But over several months, this is somewhat smoothed out somewhat.
