Family of steroid hormones produced by ovaries and placenta. Major hormone is oestradiol, see above.
female steroid hormone that promotes female characteristics and plays a role in the menstrual cycle.
a general term for female steroid sex hormones that are secreted by the ovary and responsible for typical female sexual characteristics
The hormone that is responsible for female development. It is involved with the menstrual cycle, keeping a healthy vaginal lining and breast growth. Men also produce the Oestrogen hormone.
A hormone that aids the thickening of the endometrium lining. It is also produced in small quantities in the male.
A term used to describe hormones with the same action as oestradiol.
A hormone produced by the ovary in increasing amounts prior to ovulation.
A hormone produced by the ovary, necessary for the development of female secondary sexual characteristics.

It is produced mainly by the ovaries. It is a hormone that is responsible for the development of sexual characteristics.
One of the two female sex hormones.
One of a group of female sex hormones (including oestradiol) that controls the development of female secondary sex characteristics and promotes the growth and maintenance of the female reproductive system. Oestrogens are made mainly by the ovary, but also in the placenta and small amounts in the testis
A hormone which prepares a woman for fertility. Synthetic preparations may have different effects.
A femal sex hormone produced by the ovaries which stimulates the endometrium to grow and thicken.
The major female hormone that causes the breasts to develop in young girls and causes development of the uterus (womb). This hormone also can stimulate the growth of breast cancer tissue.
A hormone produced by the ovaries which plays many roles throughout the body, but is particularly influential, along with the hormone progesterone, in regulating the reproductive cycle.
Oestrogen is one of the most important female sex hormones. It is particularly important in cancer research as it is able to encourage the growth of certain cancers, notably breast and ovarian cancer.
a female hormone produced by the ovary in varying amounts throughout the menstrual cycle
Generic name for one of the main groups of female sex hormones (U.S.A. spelling 'Estrogen').
a sex hormone dominant in women, produced by the large growing follicles in the ovary.
A hormone, produced mainly by the ovaries, responsible for female sexual development and female secondary sex characteristics. Increasing oestrogen levels in the follicular phase (pre-ovulatory phase) of the cycle stimulates significant changes in the cervix, cervical mucus, and the endometrium.
A major category of female hormones.
The sex hormone that matures eggs within the ovaries, stimulates the thickening of the walls of the uterus in preparation for implantation and prompts the production of cervical mucus favourable to sperm. It's produced by the follicles within each ovary between your period and ovulation.

A hormone commonly used by transexual women.
Female natural or synthetic sex hormone which has multiple effects, including maintenance of the menstrual cycle. Oestrogens are responsible for the maturation of the female reproductive organs (ovary, uterus, vagina, fallopian tubes) and the development of secondary sexual characteristics (breasts and general body shape). Their cyclical variations ensure female fertility. Their other important effects include regulation of normal bone tissue calcification, protection of blood vessels against the harmful effects of cholesterol, and, in the central nervous system, delay of cerebral ageing.
