Editorial Reviews

Review

"I am so thankful to Lisa for writing The Fifth Vital Sign -- a book that contributes immeasurably to the field of fertility awareness. Using impeccable research standards, she has made her book easily accessible while being scientifically sound -- a goldmine of practical advice for women wanting answers to the myriad of questions that usually arise around fertility and the menstrual cycle."
-- Toni Weschler, MPH, author of Taking Charge of Your Fertility and Cycle Savvy
 
"With The Fifth Vital Sign, Lisa dives deep into the menstrual cycle and fertility and provides valuable new insights gleaned from more than 150 interviews with women's health experts! It's a reference that I will undoubtedly refer to again and again."
--
Lara Briden, ND, author of Period Repair Manual
 
"The Fifth Vital Sign is an essential book for every woman's library. Lisa blends science, tradition, and intuition in her writing -- the result is a beautiful and practical guide to all things fertility!"
--
Dr. Fiona McCulloch, ND, author of 8 Steps to Reverse Your PCOS
 
"The Fifth Vital Sign educates and empowers women to take control of their cycles and reach beyond to take charge of their total health. I could not recommend it more highly."
--
Amy Medling, founder of PCOS Diva and author of Healing PCOS
 
"At last, a book celebrating the menstrual cycle as the vital sign it is, an indicator of our overall health. Packed with useful information written in a warm, engaging style, The Fifth Vital Sign shows you how to take charge of your hormonal health and contraceptive needs in a way that nourishes and empowers. A must-have for all women in their menstruating years."

Alexandra Pope and Sjanie Hugo Wurlitzer, co-authors of Wild Power
and co-directors of Red School

About the Author

Lisa Hendrickson-Jack talks about vaginas a lot! She's a certified Fertility Awareness Educator and Holistic Reproductive Health Practitioner who teaches women to chart their menstrual cycles for natural birth control, conception, and monitoring overall health. In her new book The Fifth Vital Sign, Lisa debunks the myth that regular ovulation is only important when you want children, by recognizing the menstrual cycle as a vital sign. Drawing heavily from the current scientific literature, Lisa presents an evidence-based approach to fertility awareness and menstrual cycle optimization. She hosts the Fertility Friday Podcast, a weekly radio show devoted to helping women connect to their fifth vital sign by uncovering the connection between menstrual cycle health, fertility, and overall health. With well over a million downloads, Fertility Friday isthe #1 source for information about fertility awareness, and menstrual cycle health, connecting women around the world with their cycles and their fertility -- something our education systems have consistently failed to do. When she's not researching, writing, and interviewing health professionals, you'll find her spending time with her husband and her two sons.
