Aromatherapist Valerie Worwood suggests two massage blends using these oils diluted in 2 TB carrier oil:
Formula #1
Geranium 20 drops
Rose 5 drops
Nutmeg 5 drops
Formula #2
Fennel 15 drops
Geranium 10 drops
Coriander 5 drops
She does not say to do both blends, but offers them as two good blends. Massage on abdomen over the ovaries. She recommends 6 drops of Geranium added to bath water.

Treatment for men and women is the same, except that women should start theirs on the last day of their period and men should continue treatment for at least three months.
Worwood also suggests that one could add 5 drops of essential oil(s) above to 1 teaspoon of carrier oil and apply over the whole abdomen, the hips, across the lower back and into the crease of the buttocks, but not as far as the anus. For a bath, add 6-8 drops to bath water (I would suggest adding to bath salts first and then to the warm bath water.)
Worwood mentions that Zinc deficiency may be a factor for both male and female infertility. Good sources are fish, meat, green leafy veggies, nuts etc.
