Answer 1

To get the results for all months:

SELECT YEAR(entrydate) AS yr, MONTH(entrydate) AS mnth, gender, COUNT(*) AS cnt
FROM patient_master
GROUP BY YEAR(entrydate), MONTH(entrydate), gender

If you want it for all months of a single year:

SELECT MONTH(entrydate) AS mnth, gender, COUNT(*) AS cnt
FROM patient_master
WHERE YEAR(entrydate) = 2012
GROUP BY MONTH(entrydate), gender
