Spike Protein Effects on Reproductive Health - MCS Group


In response to growing concerns raised by obstetricians/gynecologists regarding an increase in fertility and menstruation issues among women following the advent of COVID-19 vaccinations, a new study was initiated to shed light on this emerging phenomenon.

Unveiling the Pathology: This study delves into the emerging pathology associated with COVID-19 vaccinations and sheds light on the potential effects of spike proteins on reproductive health.

The study, designed as a blinded, pathological review investigating the theory of the potential side effects of Spike Protein in the COVID-19 vaccines and the possibility of transmission of spike, creating menstrual irregularities in women. Results from previous studies warrant further investigation into the relationship between fertility and COVID-19 vaccinations.

The study aims to accomplish two critical goals. First, it intends to examine the presence of spike protein and/or mRNA in various body tissues, such as those obtained through biopsy, surgery, or blood draws, among both vaccinated and unvaccinated women within a sample set of 50 individuals. This analysis will provide valuable insights into the potential biological mechanisms underlying the observed fertility and menstruation issues.

The results of this study serve as a crucial foundation for future research in this area, emphasizing the need for a more targeted and comprehensive investigation. By exploring the presence of spike protein and mRNA in body tissues, researchers can better understand the potential impact of COVID-19 vaccinations on reproductive health.


Higher Miscarriage Rates: Shockingly, the study reveals that 32.1% of reported pregnancies post-January 1, 2021, ended in miscarriage, surpassing the typical national age-standardized miscarriage rates of 12.8%.


Unprecedented Cases of Decidual Cast Shedding: In an unexpected turn, the study reports 4.9% of respondents experiencing decidual cast shedding, a condition rarely seen in previous medical history.

As more data becomes available, it is imperative to expand our knowledge and deepen our understanding of any potential connections between COVID-19 vaccinations and fertility-related issues. Further research is vital to verify these preliminary findings and provide comprehensive insights into the implications for women’s reproductive health.
