sex hormones also contribute to the basic health of the heart, bones, liver, and many other tis-sues. Finally, during pregnancy the placenta produces a hormone (human chorionic gonado-tropin, or hCG) that signals the body to support the preg-nancy. A woman is born with all of the eggs that she will ever have. Therefore, if her eggs are damaged

men after age 65. The decline in IBS after menopause indicates again that sex hormone fluctuations play a part in producing the symptoms, because such fluctuations cease after menopause. With all these indications of female sex hormones playing a role in IBS symptoms, one might ask whether the male sex hormone testosterone also influences IBS.

in female one [7], although it remains unclear if there is a higher prevalence in one specific gender, as the prevalence female/male ratio ranges from 0.8 to 3.8 [8]. In women, the onset age is bimodal, with the first peak between 13 and 16 years and the second peak almost a decade later, between 22 and 32 years. These peaks coincide with

Typically MTF hormone therapy involves estrogen, medication to block testosterone, or a combination of the two. Sometimes a progestagen is added to the mix. 1.

BioIdentical Hormone Replacement Therapy for Women

They are changed in a laboratory so that the hormones produced are identical in shape and function to human hormones. As a result they cannot be patented, so Big Pharma does not really like them.

Interstitial Cystitis: The Estrogen Connection

therefore, female sex hormones are hypothesized to play a role in the disorder. My hypothesis is that estrogen, both endogenous and synthetic, affects the severity of IC symptoms. Through surveying the available literature on interstitial cystitis, I have found that IC symptoms often correlate with low estrogen. My hope is that by understanding

Chapter 18: Endocrine and Reproductive Systems

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) control the growth, development, and functions of the gonads, another name for the ovaries and testes. In females, FSH stimulates cells in the ovaries to produce estro-gen, a female sex hormone that triggers the development of ova. LH is responsible for ovulation and stimulates

In a similar manner, the adrenal, thyroid, and sex hormones work in harmony, and when one or more of the hormones in any one system become unbalanced, this affects the harmony or balance of the whole system. Symptoms common to hormonal imbalances in the endocrine systems are seen as the body struggles to maintain balance, but does not succeed.

The action of the hormone changes the condition of the tissue. This change in monitored through feedback. Most hormonal change results in negative feedback. Key

ovaries have two important functions: they produce the female sex hor-mones estrogen and progesterone, and they release mature egg cells. The sex hormone activates certain physical changes at puberty, such as breast development, and controls the maturation of eggs. activates changes to a woman s reproductive system before and during pregnancy.

Sex determination One of the 23 pairs of chromosomes is the sex chromosomes. Females have two X chromosomes, so egg cells normally contain one X-chromosome. Males have an X and a Y chromosome, so sperm can have either. Fertilisation by an X-carrying sperm gives a female, by a Y-carrying sperm gives a male. Erection of the penis
