Term Stim™ is a comprehensive reproductive-physiology consulting service, not a single protocol. It applies a new understanding of the reproductive cycle to analyze individual poor-egg-quality cases to uncover the likely reasons for poor egg quality and assist physician in developing a protocol that addresses them in that specific patient.
We have chosen the name “Term Stim™” for Repronova services to highlight that it is as comprehensive and complete as a term (delivered at the full gestation) newborn. It also reflects on one of the unique consequence of the new ovulation paradigm – that egg competence requires “term”. Please note, that not every Term Stim™ protocol requires carrying follicles to term and, in some cases, the protocol does not even include ovarian stimulation component.
Term Stim™ is delivered in collaboration with the ordering physician, using a research-grade Repronova EMR built to analyze patient data in the context of this new physiology.
In 2020 we corrected an 80-year misconception at the very core of human reproductive physiology explaining why progesterone, not estradiol, is a physiological trigger of ovulation.
The new ovulation paradigm offers a unifying framework for several phenomena that had remained unresolved for decades: the variability and age-related shortening of the menstrual cycle, the consistency of single-egg ovulation, the link between vanishing follicles and post-mature oocytes, the impact of follicular-phase duration on egg quality, and the mechanisms of reproductive aging – even providing a new explanation for key features of PCOS.
It also introduced the concept of term maturation of the egg – the idea that, much like gestation, an oocyte requires a minimum “term” of development to reach full competence. Early clinical evidence, including published case reports, supports this concept.
The new ovulation paradigm has completely reshaped our view of reproductive cycle and identified new entry points to control egg quality.
In medicine, AI is very successful at searching for and applying a template that worked for a similar patient. But in cases of poor egg quality, this approach is rarely fruitful, since each case is unique. Therefore, in Term Stim™, we use AI only to help track relevant variables and identify subtle trends in a patient’s data that might otherwise be overlooked. However, all validation, interpretation, and recommendations remain entirely human – grounded in research, experience, and expertise.
