This is due to the fact that the levels of progesterone, a hormone that promotes menstruation and reduces interest in sex, increase before ovulation. However, the researchers in the new study found no correlation between a woman’s loss of interest in sex and a surge in the hormone luteinizing hormone (LH), suggesting that the woman’s partner’s hormonal changes were not the cause of a woman’s loss of interest in sex. ADVERTISEMENT The researchers used a test to measure levels of the stress hormone cortisol – which is associated with stress – and testosterone, which is associated with interest in sex.
