Along with other complaints, the activities of the popes between 1458 to 1565, helped encourage the Protestant Revolt.
Pope Sergius III (904–911) was supposedly the father of Pope John XI by Marozia. Bertrand Fauvarque underlines that the
sources backing up this parenthood, notably Liutprand of Cremona in his Antapodosis are dubious, Liutprand being "prone
to exaggeration" while other mentions of this fatherhood appear in satires written by supporters of late Pope Formosus.
Pope John XII (955–963) (deposed by Conclave) was said to have turned the Basilica di San Giovanni in Laterano into a
brothel and was accused of adultery, fornication, and incest.

Ave Maria purissima prega per noi! LOL!
Pope Benedict IX (1032–1044, again in 1045 and finally 1047–1048) was said to have conducted a very dissolute life during his papacy.
Pope Alexander VI (1492–1503) had a notably long affair with Vannozza dei Cattanei before his papacy, by whom he had his famous
illegitimate children Cesare and Lucrezia. A later mistress, Giulia Farnese, was the sister of Alessandro Farnese, who later
became Pope Paul III. He fathered a total of at least seven, and possibly as many as ten illegitimate children.
Sexually active after receiving Holy Orders
Pope Julius II (1503–1513) had at least one illegitimate daughter, Felice della Rovere (born in 1483, twenty years before his
election). Some sources indicate that he had two additional illegitimate daughters, who died in their childhood.
Pope Paul III (1534–1549) held off ordination in order to continue his promiscuous lifestyle, fathering four illegitimate
children (three sons and one daughter) by his mistress Silvia Ruffini.

LOLROTF! He broke his relations with her ca. 1513.
There is no evidence of sexual activity during his papacy.
Pope Pius IV (1559–1565) had three illegitimate children before his election to the papacy.

LOLROTF!!!
There's actually more.
