A woman’s fertility at age 35 is 50% of that at age 25, dropping to 25% by age 38, and can drop further to less than 5% beyond age 40. Despite the advances and optimization of assisted reproductive technologies, a woman’s age remains one of the most important factors affecting pregnancy success. In a word, age is an important factor for fertility, but not the absolute only one! Under normal circumstances, couples with normal fertility have a 20%-25% pregnancy rate in a single month, a 75% pregnancy rate in six months and a 90% pregnancy rate in one year. If you have been infertile for more than 4 years, the pregnancy rate is only about 1 .5% per month. Therefore, if the male partner’s semen routine examination is abnormal in just one item, it can affect the ability to fertilize, thus decreasing the successful conception rate! Currently, the most important medications for regulating sperm quality are mainly based on herbal medicine, and it is also crucial to change poor lifestyle (e.g. smoking, alcoholism, etc.).
