Can sun exposure improve female fertility?

In a recent study published in the Human Reproduction journal, researchers have found a potential link between sunlight exposure and female fertility.

The study, involving over 6,000 women undergoing 𝐢𝐧 𝐯𝐢𝐭𝐫𝐨 𝐟𝐞𝐫𝐭𝐢𝐥𝐢𝐳𝐚𝐭𝐢𝐨𝐧 (𝐈𝐕𝐅) treatment, suggests that 𝐡𝐢𝐠𝐡𝐞𝐫 𝐥𝐞𝐯𝐞𝐥𝐬 𝐨𝐟 𝐬𝐮𝐧 𝐞𝐱𝐩𝐨𝐬𝐮𝐫𝐞 𝐦𝐚𝐲 𝐢𝐧𝐜𝐫𝐞𝐚𝐬𝐞 𝐭𝐡𝐞 𝐜𝐡𝐚𝐧𝐜𝐞𝐬 𝐨𝐟 𝐩𝐫𝐞𝐠𝐧𝐚𝐧𝐜𝐲 success.Women who had greater exposure to sunlight in the month prior to their IVF procedure more likely achieved pregnancy compared with those with lower exposure levels. While the exact mechanisms behind this association remain unclear, researchers 𝐬𝐩𝐞𝐜𝐮𝐥𝐚𝐭𝐞 𝐭𝐡𝐚𝐭 𝐬𝐮𝐧𝐥𝐢𝐠𝐡𝐭 𝐞𝐱𝐩𝐨𝐬𝐮𝐫𝐞 𝐦𝐚𝐲 𝐢𝐧𝐟𝐥𝐮𝐞𝐧𝐜𝐞 𝐥𝐞𝐯𝐞𝐥𝐬 𝐨𝐟 𝐦𝐞𝐥𝐚𝐭𝐨𝐧𝐢𝐧, a hormone known to regulate sleep-wake cycles and 𝐫𝐞𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐯𝐞 𝐡𝐨𝐫𝐦𝐨𝐧𝐞𝐬.
