Modelling through mathematical is becoming a plentiful valuable tool for medical field. A mathematical model using fuzzy couple parameter log-logistic distribution, fuzzy survival and fuzzy hazard rate function and its $\alpha$-cut sets were presented. In the paper we developed a mathematical pattern using the fuzzy log-logistic distribution for the effect of young women on hypothyroidism hormone.
