Infertility refers to an inability to conceive after having regular unprotected sex. Infertility can also refer to the biological inability of an individual to contribute to conception, or to a female who cannot carry a pregnancy to full term. In many countries infertility refers to a couple that has failed to conceive after 12 months of regular sexual intercourse without the use of contraception.

Studies indicate that slightly over half of all cases of infertility are a result of female conditions, while the rest are caused by either sperm disorders or unidentified factors.

A woman’s fertility starts to drop after she is about 32 years old, and continues doing so. A 50-year-old man is usually less fertile than a man in his 20s (male fertility progressively drops after the age of 40).


Risk factors for infertility are : Smoking , Alcohol consumption, Being obese or overweight , Eating disorders , Folic acid and Vit B12 deffiency, Over-exercising or Not exercising at all, Sexually transmitted infections, Exposure to some chemicals, Mental stress.

Optimization of Metabolic parameters through BHRT helps in promoting spontaneous conception and improves the success rate of assisted conception. It also helps maintain pregnancy in order to take it to a successful outcome of a healthy mother and child. Specifically T3, Vit B12 and Progesterone play important roles.
