Celery can contribute to good fertility health. Though it is not recognized as a fertility booster on its own, it does contain several nutrients vital to fertility health. For instance, it has small amounts of folate or Vitamin B9, which is known to help improve fertility. A stalk of celery contains around 34 micrograms of folate (8.5% of daily recommend value), which is crucial in maintaining DNA integrity and promoting ovulation in women and sperm viability in men.
