Black seed shows promising results for fertility — particularly for men. Take half a teaspoon of cold-pressed black seed oil daily in the morning on an empty stomach. For fertility support, consistency over at least 8–12 weeks is essential before expecting results.
For men, research shows black seed oil may improve sperm count, sperm motility, and sperm morphology — the three key markers of male fertility. It also helps reduce oxidative stress in reproductive cells, which is one of the most common underlying causes of unexplained male infertility.
For women, black seed may help regulate hormonal imbalances and reduce inflammation in the reproductive system — both of which can affect ovulation and cycle regularity. The evidence for women is less established than for men but still promising.
💡 Why it works: Thymoquinone in black seed is a powerful antioxidant that protects reproductive cells from oxidative damage. It also supports healthy testosterone levels in men and may help balance oestrogen and progesterone in women by reducing inflammation in the endocrine system.
⚠️ Important: Black seed oil should be stopped as soon as pregnancy is confirmed — it may stimulate uterine contractions in larger amounts. If you are undergoing fertility treatment or taking fertility medication, always consult your doctor before adding black seed oil to your routine. It is a supplement — not a fertility treatment.
