The health benefits of chocolate may improve fertility.
In Mayan civilization, ground cocoa was thought to be a health-promoting elixir, and the Aztecs believed that cocoa pods symbolized life and fertility. Throughout history, chocolate has been used to treat a wide variety of ailments, and in recent years, multiple studies have found that chocolate can have positive health effects, providing evidence to a centuries-long established use.
Beneficial fertility-related components of dark chocolate (with a cacao content of 70% or higher) include it's antioxidants (beneficial for egg and sperm health), and it's anti-inflammatory actions that improve the bioavailability of nitric oxide, which contributes to improving platelet function and blood flow (an important part of how "nutrition" gets to the uterine environment).
A traditional hot chocolate preparation involved adding cinnamon and pepper - these are both Chinese herbs that "warm the uterus," or also help blood flow. So, chocolate can be a pleasurable and healthy indulgence to incorporate (in moderation) into your fertility routine.
