1. Estradiol
Estradiol has a critical impact on reproductive and sexual functioning. It supports the lining of the vagina, the cervical glands, the endometrium and the lining of the fallopian tubes. If the levels of remain low on the first 10 days during menstrual cycle, it may interfere with ovarian eggs production leading to poor quality egg and infertility.

2. Luteinizing hormone (LH)
With the rise of estrogen, LH receptors are also expressed on the maturing follicle that produces an increasing amount of estradiol leading to ovulation and stimulates the production of progesterone. Abnormal of LH may interfere the natural ovulation leading to infertility.

3. Follicle stimulating hormone (FSH)
FSH stimulates the growth and recruitment of immature ovarian follicles in the ovary in the early stage of menstrual cycle. Unbalance of FSH may interferes with the growth of immature follicle and ovulation.

4. Progesterone.

It helps to make cervical mucus thick and impermeable to sperm, prepare the uterine lining for implantation of fertile egg and increase immune system acceptance of the pregnancy, decreases contractility of the uterine muscle and inhibits lactation during pregnancy.
