In Aldous Huxley's Brave New World, the "World State" maintains strict control over every facet of every human's existence, including, and especially, their sexuality and reproductivity. In Chapter Three, Lenina and Fanny, with Mustafa, are discussing their social lives, which invariably involves discussions of sexuality. Naked in a communal bathroom, the women begin turn their discussion towards their hormonal processes, prompting the following exchange:
“Who are you going out with to-night?” Lenina asked, returning from the vibro-vac like a pearl illuminated from within, pinkly glowing.
Lenina raised her eyebrows in astonishment.
“I’ve been feeling rather out of sorts lately,” Fanny explained. “Dr. Wells advised me to have a Pregnancy Substitute.”
“But, my dear, you’re only nineteen. The first Pregnancy Substitute isn’t compulsory till twenty-one.”
Fanny's comment that she is feeling "out of sorts" is interpreted here to suggest she is not feeling sexual, probably related to her menstruation cycle. The "Pregnancy Substitute," we can infer, is intended by the state to manipulate a woman's hormonal status for the purpose of reinvigorating her libido. Lenina then proceeds to read the ingredients and procedures associated with this "substitute":
“SYRUP OF CORPUS LUTEUM,” Lenina read the names aloud. “OVARIN,
GUARANTEED FRESH: NOT TO BE USED AFTER AUGUST 1ST, A.F. 632.
MAMMARY GLAND EXTRACT: TO BE TAKEN THREE TIMES DAILY, BEFORE
MEALS, WITH A LITTLE WATER. PLACENTIN: 5cc TO BE INJECTED
INTRAVENALLY EVERY THIRD DAY. Ugh!” Lenina shuddered. “
In Huxley's dystopian universe, the all-seeing, all-knowing government has developed the technological and pharmaceutical means of controlling even the most personal and intrusive human activities.
