The probability of pregnancy promotion with urotropins is very high and is mainly used for women with the possibility of immature egg cells being expelled. Urotrophin can promote the development of female follicles and the discharge of mature eggs, thus increasing the probability of conception. The use of gonadotropins is risky and may lead to the development and maturation of multiple follicles, which can easily lead to ovarian hyperstimulation syndrome and even serious consequences. Long-term use of urotropin may increase the probability of developing malignant tumors of the reproductive system and is not recommended for long-term use. It is best to monitor ovulation after use and avoid strenuous exercise and trauma to the abdomen to prevent rupture of the ovaries, which can lead to acute abdominal pain and even life-threatening intra-abdominal hemorrhage. Avoid staying up late at night to prevent endocrine disorders.
