Yes, low levels of both hormones could affect fertility, generally negatively. FSH stands for follicle stimulating hormone - without the constant stimulation of this hormone, a follicle will not develop to the point of being a fertile egg or oocyte. LH stands for luteinizing hormone and is the hormone responsible for causing a fertile oocyte to rupture from the ovary and travel into the Fallopian tube where it can be fertilized.
When the level of follicle-stimulating hormone (FSH) is low, it can lead to impaired reproductive function. In women, low FSH can disrupt ovarian function, resulting in irregular menstrual cycles or amenorrhea, and may lead to infertility. In men, low FSH can affect spermatogenesis, resulting in reduced sperm production and potential infertility. Overall, low FSH levels can indicate issues with the pituitary gland or the hypothalamus, affecting overall hormonal balance.
Anorexia nervosa and disorders of the hypothalamus or pituitary gland can result in abnormally low FSH levels. Abnormal levels can also indicate: infertility hypopituitarism klinefelter syndrome (in men) turner syndrome ovarian failure
Follicle Stimulating Hormone stimulates follicle and egg maturation in females and stimulates sperm production and maturation in males. Therefore low levels of FSH slows spermatogenesis.
At 52, many women are approaching or experiencing menopause, which is characterized by low estrogen levels and often elevated follicle-stimulating hormone (FSH) levels. While it's still possible to become pregnant during the perimenopausal phase, lower estrogen and higher FSH typically indicate reduced ovarian function and lower fertility. Therefore, while pregnancy is technically possible, the likelihood diminishes significantly with these hormonal changes. Consulting a healthcare provider for personalized advice is recommended.
No, this is not true. FSH starts to suppress during pregnancy. LH remains low throughout lactation, but begins to rise again during weaning.
During days 15-28 of the menstrual cycle, the decrease in FSH levels is due to the negative feedback effect of rising estrogen levels. As estrogen levels increase, they signal the pituitary gland to reduce FSH production. This decrease in FSH helps prevent multiple egg development and allows for the maturation of a single dominant follicle.
Low FSH levels after hysterectomy can lead to hormonal imbalances and symptoms like hot flashes and mood swings. Management strategies may include hormone replacement therapy to restore hormonal balance and alleviate symptoms. Regular monitoring of hormone levels and discussing any concerns with a healthcare provider is important for managing this condition effectively.
Blood type does not affect cholesterol levels. Heredity, eating low-fat foods, and exercise all do affect cholesterol levels.

Hypoxemia (low oxygen levels in the blood) will affect the entire brain.
In the beginning of the menstrual cycle, LH and FSH stimulate the ovaries to make estrogen. During this time, there is a negative feedback loop, so levels of all three hormones are rather low. Eventually, as the estrogen levels slowly creep up, there comes a time when it switches from negative feedback to positive feedback (not exactly sure what the biochemical basis of this is), and LH and FSH levels skyrocket (estrogen levels go up to, but not as sharply, and there is always more LH than FSH). The LH surge causes ovulaton. The corpus luteum starts secreting progesterone, which inhibits LH and FSH secretion in a negative feedback manner, and so FSH and LH levels drop sharply.
For a premenopausal woman, normal values range from 4-30 U/L or 5-20 micro-international units per milliliter. In a pregnant woman, FSH levels are too low to measure. After menopause, normal values range from 40-250 U/L
