I had problems with infertility. After six years of marriage I had no children. I visited a tohunga who shared with me the following recommendations to improve fertility.
- Do not masturbate for at least three weeks prior to trying for children
- Give the female crayfish eggs to eat
- Do not masturbate at all until your child has been conceived
Another technique was for a donor (sometimes the advising tohunga) to ejaculate onto a kawakawa leaf and tell the male to wipe this on his partners vagina before intercourse.
