José María Murcia Lora, MD, OB-GYN, PhD.   Introduction The purpose of this work is to review the contribution that viscoelasticity and transparency can make, as a signal and biophysical marker of cervical secretion in the recognition of the fertility of the fertile window, based on the Creighton model (CrMs). The objective of this brief introduction is to point out those concepts that are relevant to the changes observed in cervical secretion, and explain the production of estrogens by endocervical cells. For this, it is convenient to review some basic concepts of the physiology of ovulation involved in the evolution […]

  Marguerite Duane1,2, MD, MHA, FAAFP.  1Georgetown University, 2 Fertility Appreciation Collaborative to Teach the Science With Fertility Awareness Based Methods (FABMs), women learn to chart the signs of the reproductive cycle so they can monitor their health and identify when they may be fertile or not for family planning purposes. Additionally, women can work with FABM trained physicians to receive more targeted diagnosis and management of common gynecologic concerns. However, accurate and complete information about these methods are rarely included in medical curricula, impeding future professionals from using this information to provide more well-rounded health care options to patients.

Abstract: Fertility-tracking apps are extremely popular; they are the fourth most common health app among adults and second most popular among adolescent females (Moglia et al. 2016).  The Natural Cycles app is effective in preventing pregnancy when combined with barrier use during the app-identified fertile window. It employs a proprietary with barrier use during the app-identified fertile window. It employs a proprietary algorithm using daily Basal Body temperature (BBT) to define the fertile window. The CycleProGo (CPG) app, developed by Couple to Couple League […]
