Hormone treatment in women aims to promote egg maturation and trigger ovulation. This increases the likelihood of successful fertilization. The success rates for each treatment cycle can vary greatly depending on the age of the women and the extent of the underlying hormone disorder, ranging between 10 and 20%.

The woman may get a blood test to check her levels of follicle-stimulating hormone, or FSH, which triggers her ovaries to prepare an egg for release each month. High FSH can mean lower fertility in women. The FSH blood levels get checked early in your menstrual cycle (often on day 3).

Testing hormone levels for male factor infertility and reproduction:

Important chemicals in the men's bodies, called hormones, control sperm production. Too much or too little of these hormones can cause problems with sperm production or trouble having sex. Two important hormones for reproduction are follicle-stimulating hormone (FSH) and testosterone (T). The doctor may do blood work to check to see if the male has the right amount of these hormones. If indicated, the doctor may check other hormone levels, including luteinizing hormone (LH), estradiol, and prolactin.
