SB 9.1.40

acaryanugrahat kamam
 labdhva pumstvam vyavasthaya
palayam asa jagatim
 nabhyanandan sma tam prajah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thus being favored by the spiritual master, according to the words of Lord Siva, Sudyumna regained his desired maleness every alternate month and in this way ruled the kingdom, although the citizens were not satisfied with this.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The citizens could understand that the king was transformed into a female every alternate month and therefore could not discharge his royal duty. Consequently they were not very satisfied.
