Fertility Hormones test







What causes female infertility?

About one quarter of female infertility is caused by a problem with ovulation. This can be due to an imbalance of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). FSH & LH help normal follicular growth. Luteinizing hormone (LH) plays a key role in gonadal function. LH in synergy with follicle stimulating hormone (FSH) stimulates follicular growth and ovulation. LH plays complimentary to FSH
Thus, normal follicular growth is the result of complementary action of FSH and LH.


What happens if FSH hormone is high?

High FSH is found in women nearing menopause. High levels of follicle stimulating hormone (FSH) in a woman’s blood could reduce chances of getting pregnant. High FSH indicates failing ovaries. There is no treatment available when FSH level rises and couple are offered egg donation programme to procure a baby.

What is the role of LH hormone in female reproduction?

LH is important for oocyte maturation. LH along with FSH regulate steroidogenesis throughout follicular development.
LH also stimulates the conversion of progesterone into androgens which helps to maintain pregnancy. High LH levels are found in PCOS and indicates low quality of oocytes.




How progesterone helps fertility?

Progesterone, prepares the uterus of a woman to get pregnant.
The ovaries produce the progesterone hormone just after ovulation. Progesterone levels generally peak one week after ovulation. Throughout pregnancy progesterone levels remain high and prevents abortion or premature deliveries. In IVF treatment progesterone preparations are given to help implantation and sustain pregnancy.

How important is AMH in female reproduction?

Anti-mullerian hormone (AMH) predicts ovarian reserve. AMH is produced by the very small pre-antral stages of ovarian follicles. AMH testing can be done on any day of the woman’s cycle. High AMH is seen with PCOS and low AMH in patients with low ovarian reserve. Usually women with very low AMH do not produce eggs and are advised for oocyte donation programme.


Why Prolactin is tested in female infertility evaluation?

Prolactin (PRL), hormone helps females, to produce milk.
High levels of Prolactin can be caused by pituitary tumours.
Prolactin is produced by the pituitary gland in the brain. Elevated prolactin levels interfere with the secretion of reproductive hormones from the brain (hypothalamus), resulting in a decrease in circulating levels of estrogen (female). This can lead to infertility, menstrual irregularity, and absence of menstruation, and loss of sexual interest in women.




How thyroid hormone affects fertility?

Normal TSH levels are the pre-requisites for fertilization. Undiagnosed and untreated thyroid disease can be a cause for infertility. Normal thyroid function is necessary for fertility and to sustain a healthy pregnancy. Low thyroid hormone levels (Hypothyroidism) influences ovarian function by decreasing levels of sex-hormone-binding globulin and increasing the secretion of prolactin. In women of reproductive age, hypothyroidism can be reversed by thyroxine therapy to improve fertility and avoid the need for use of assisted reproduction technologies.




Can oestrogen play a role in infertility?

Oestrogen is one of the most important female reproductive hormones which is produced by the developing follicles in a woman’s ovaries. Oestrogen prepares the endometrium of uterus for implantation. Abnormal levels of estradiol, an important form of oestrogen, decreases chances of IVF success. A woman’s ovarian function and quality of eggs can be evaluated through testing oestrogen.

PCOS INFORMATION

Which is the most common hormone disorder found in women? Polycystic ovary syndrome ( PCOS ) is extremely prevalent and probably constitutes the most frequently encountered endocrine (hormone) disorder in women of reproductive age. Having the disorder may significantly impact the quality of life of women during the reproductive years, and it contributes to morbidity and mortality by the time of menopause. What are the disorders associated with PCOS? PCOS women are at increased risk for coronary heart disease and type 2 diabetes mellitus. Their risk factors include central obesity, hypertriglyceridemia, low levels of high-density lipoprotein (HDL) cholesterol, hypertension, and elevated fasting plasma glucose concentrations. PCOS women should undergo screening for hypertension, abnormal lipid profiles, insulin resistance, and reproductive disorders including cancer of endometrium. What is PAO? A subgroup of women (up to 30%) may have subtle abnorma...

Surgeries that can enhance fertility

Surgeries that can enhance fertility Fertility enhancing surgeries are usually advised to young women with suspected minimal to moderate disease of tubes, ovaries or uterus. These surgeries may enhance the rate of spontaneous pregnancy or IUI treatment. Usually such surgeries are done by experts through laparoscope to prevent damage to pelvic organs. Fertility enhancing surgeries in female infertility Myomectomy  : Uterine fibroids are the most common tumours in the female. Fibroids in infertile women undergoing assisted reproductive treatment can decrease success rates than do age-matched women with no fibroid. Removal of fibroids(myomectomy) can help these cases. However, myomectomy is restricted to women with unexplained infertility. If you have fibroids growing into the uterine cavity then you are more likely to benefit after  myomectomy . Higher pregnancy rates can be achieved after laparoscopic removal than open surgery. This procedure can be considered i...
