Fertility Astrology, Medical Astrology, Electional Astrology. This archival document is a lecture manuscript titled “FERTILITY, INFERTILITY and ASTROLOGY” by Marion D. March, dated around 1991 to 1996. March expands upon her research into Dr. Eugen Jonas’s lunar-solar fertility cycle and its integration with modern reproductive medicine. She reiterates that astrological fertility cycles are highly unreliable for birth control, but serves as a powerful electional tool for timing pregnancies. The manuscript provides guidelines for electing conception windows based on applying lunar aspects, natal chart distance matching, and managing timing relative to physical ovulation and biological constraints. March addresses assisted reproductive procedures including artificial insemination, in-vitro fertilization (IVF), GIFT, and ZIFT, asserting that the critical electional moment for astrological timing occurs at embryo implantation rather than egg harvesting or fertilization. The text features technical client worksheets, correspondence, case studies, and discussions on gender prediction, lunar sign polarities, and navigating pregnancy complications.
