Luteinizing Hormone Releasing Hormone
Turns yellow: Luteining hormone is a peptide (not a steroid) hormone in the pituitary gland of both females and males. Its name (lh) comes from one of its actions in females, which is 'luteinization' of ovarian granulosa cells. Luteinization means literally to 'turn yellow.' luteinization is a necessary change in the ovary so that it can produce Progesterone after ovulation. ...Read more
Luteinizing hormone (lh) is released by the master gland (pituitary) in the brain to cause ovulation. The egg is released from the ovary and ready to be fertilized. The ovary also then produces Progesterone to prepare the inside lining of the uterus for implantation of the fertilized egg and support it until the placenta takes over production ...Read more
Nothing: Luteinizing hormone is made by the pituitary gland. In men in stimulates the testes to make testosterone, in women it stimulates the ovaries to make estrogen as well as egg production. In women, there is natural cycle to the amount of lh made throughout the month. If your level is low, one needs to investigate for pituitary or hypothalamic problems. Taking hormones will also lower lh levels. ...Read more
Time in cycle: Your hormones greatly fluctuate during different phases in your cycle. There are charts usually attached to lab reports that tell you what the average would be for where you are in your cycle. ...Read more
Leydig cells: Luteining hormone is a peptide hormone in the pituitary of females and males. Its name (lh) comes from an action in females, which is 'luteinization' of ovarian granulosa. In males lh stimulates the leydig cells of the testes to make testosterone. Please notice that unless done under supervision and in appropriately screened men, this is not an approved use and may be dangerous. ...Read more
Stimulates Ovulation: Luteinizing hormone (lh) is released by the master gland (pituitary) in the brain to cause ovulation. The egg is released from the ovary and ready to be fertilized. The ovary also then produces Progesterone to prepare the inside lining of the uterus for implantation of the fertilized egg and support it until the placenta takes over production of this vital hormone. ...Read more
Depends: Right before ovulation occurs, there is a spike in the level of luteinzing hormone (lh). This triggers the release of the egg from the ovary. However high levels of lh are associated with menopause or polycystic ovarian syndrome (pcos). High lh in pcos cause there to be no ovulation and an increase in androgens that can cause hair growth on face & chest. These are a few examples. ...Read more

Hormone imbalance: Lh is responsible for ovulation in women, as well as production of testosterone in both women and men. If it is suppressed, it usually means the hypothalamus is dysfunctional such as in long distance runners. There are many causes for hypothalamic dysfunction which can lead to hypogonadism (reduction in hormone production in the ovary or testicle). ...Read more
Around ovulation: At this point in your cycle there is a surge in both LH and FSH but much more so in the case of LH. ...Read more
Medication: First, the cause of the low luteinizing hormone (lh) and follicle stimulating hormone (fsh) levels needs to be determined. Second, the answer may be different for men versus women. Sometimes lifestyle changes are enough to correct abnormal FSH and/or lh levels. There are medications, such as Clomid (clomiphene) or inject able FSH & lh that can be helpful. See a fertility specialist and get tested, first. ...Read more
What can I do to stimulate both my luteinizing hormone (lh) and follicle-stimulating hormone (fsh) at 45?
Purified FSH: There are injections that fertility doctors use that contain fsh. In the past, pergonal (menotropins) was used to stimulate ovarian egg production and was a mixture of purified fsh and lh. To simulate the lh surge during fertility stimulation cycles, the pregnancy hormone HCG is used in high doses. ...Read more
Can you tell me about hormone physiology: what's the difference between follicle-stimulating hormone & luteinizing hormone?
FSH and LH:
I suggest that you go online to learn about FSH and LH. There are several articles designed specifically for persons who are not doctors.
Any questions after going through the articles (take your time) send in another note or question. ...Read more
My blood test shows, FSH at 0.97miu/ml and luteinizing hormone at <0.2miu/ml. I am experiencing ED and malase! What does this mean?
Tests show high Luteinizing hormone and PCOS. Other hormones look normal. Also have liver disease - how could this affect the LH result?
PCOS & Liver: With PCOS, many women have increased cholesterol. That can lead to fatty deposits in the liver as evidenced by US and by incresed ALT. The LH level is pulsatile so there is very little value in measuring it in women with PCOS. It is not one of the diagnostic criteria for determining PCOS. Focus on an insulin glucose tolerance test, androgen levels. Treatment is diet, exercise & metformin for most. ...Read more
A hormone (from greek ὁρμή, "impetus") is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Only a little amount of hormone is required to alter cell metabolism. In essence, it is a chemical messenger that transports a signal from ...Read more
Luteinizing hormone releasing hormone (LHRH), also called gonadotropin releasing hormone (GnRH), is a chemical made in the brain, and controls the release of FSH and LH. FSH and LH are two hormones made by the pituitary gland at the bottom of the brain, and are called sex hormones because they ...Read more
