Estrogen imbalance
This is about estrogen modulation, estrogen response, estrogen receptor sensitivity, estrogen deficiency, and estrogen excess. See the general blog for the latest updates.
Estrogen deficiency
Signs of estrogen deficiency, estrogen receptor desensitization or lowered estrogen response include hot-flashes, hirsutism, alcopecia and itchy skin. High body temperature typically occurs with hot-flashes. Estrogen deficiency is commonly associated with polycystic ovarian syndrome (PCOS), high luteinizing hormone (LH) and insulin insensitivity.

Estrogen excess
Signs of estrogen excess can include headache, low body temperature and heavy menstruation. Endometriosis is a concern of excess estrogen.
Receptor and enzyme modulation
From anecdoctal evidence, it seems that when aromatase enzymes, estrogen receptors or androgen receptors are sensitized in the presence of androgenic (testosterone) prominence, estrogen deficiency symptoms increase.
Aromatase is the conversion of androgens, with the exception of DHT, into estrogens.
Aromatase modulation
It happens that aromatase enzymes occur in tissue where Estrogen Receptors alpha (α) and beta (β) are present. This cellular tissue includes: ovaries, corpus luteum, uterus, breast, adrenal glands, liver, skin, muscle, bone and fatty tissue. The capability for androgen conversion into estrogen in granulosa cells within the ovaries is very important for reproductive health.
Follicle stimulating hormone (FSH) in small amounts increases aromatase synthesis, but it requires other hormones for maintaining hormone sensitivity and hormone balance.
Estrogen receptor modulation
It seems that estrogen receptor, especially ERβ, upregulation during a heavy balance of androgens increases androgenic imbalance further.
DHT modulation
DHT is a strong hormone that downregulates androgen receptors. Surprisingly, in small amounts, androgens, including DHT, can resensitize aromatase enzymes in mammals (unlike in birds and in fish). However, the outcome is likely conditional in the presence of estrogen and progesterone.
