Chaste tree berry acts on the hypothalamus and pituitary glands
by increasing luteinizing hormone (LH) production and mildly inhibiting the
release of follicle stimulating hormone (FSH). The result is a shift in the
ratio of estrogen to progesterone, in favor of progesterone. The ability of
chaste tree berry to raise progesterone levels in the body is an indirect effect,
so the herb itself is not a hormone.
Lack of menstruation (amenorrhea) that is caused by a lack of ovulation,
and therefore a lack of progesterone production, should result in menses
when progesterone is taken. Progesterone-induced menses indicates an intact
reproductive system that just isn't going through its cycle.
It suggests that the body is producing enough FSH to stimulate the
ovaries, and that the ovaries can develop follicles. It also indicates that
follicular production of estrogen is sufficient to cause the lining of the uterus
(endometrium) to grow and that the sloughed endometrium is able to pass through
the cervical opening and the vagina. Therefore it's possible that the problem
is a dysfunction in the hypothalamus or pituitary glands. The ability of
chaste tree to modulate the hypothalamus or pituitary then makes this herb a good
candidate for treating amenorrhea (infertility).
It inhibits prolactin release by the pituitary gland, especially when you
are under stress.
The Evidence for Vitex Agnus Castus
Here are some vitex studies relating to the use of the chasteberry:
Vitex and Fertility. In this study, a chasteberry preparation was used in a
study of 3,162 women to assess the effectiveness of vitex for corpus luteum
insufficiency. 77.4% had menstrual cycle disturbances of various types and the
others suffered from a range of gynecological problems which included symptoms
of corpus luteum insufficiency. The average length of treatment was 5 months.
Hormone cytology and symptoms were used to assess the treatment.
The women reported the treatment as completely effective (33%), significant
improvement (55%), and no change (7%). Their doctors reported very good results
in 68% of cases, adequate in 22%, and no change in 7%.
High levels of the hormone prolactin are commonly found with corpus
luteum insufficiency. Vitex is useful for reducing high prolactin levels.

The Vitex Fertility Solution - How Does the Vitex Fertility Solution Work?
A well known herb called Vitex or Chasteberry

in women. One of the most important factors in attempting to conceive is a
regular menstrual cycle. Can the Vitex fertility solution help with this?
has been proven time and again that Chasteberry or Vitex can correct problems
including insufficient progesterone. If a woman has insufficient progesterone, she
may be susceptible to ovarian cysts, endometriosis and uterine fibroids. So how
does Vitex work, exactly?
1. This herb increases lutenizing
hormone (LH) production and reduces or inhibits the release of follicle stimulating
hormone (FSH). These hormones are produced in the hypothalamus and pituitary glands.
This causes a change in the ratio between estrogen and progesterone, increasing
2. High levels of prolactin can be a barrier to
fertility. Vitex works to reduce the high levels of this particular
3. If a woman is not having regular periods, or has
no periods at all, the increase in progesterone should cause her to begin
menstruating, naturally. If a woman lacks progesterone, the egg may not be released,
and, of course, if the egg is not released, there is no chance
4. A daily dose of 60 drops of a tincture
containing vitex or 175 mg of an extract is recommended as a vitex fertility
There are some known drug interactions included with hormone
replacement therapy, oral contraceptives, and dopamine agonists. Of course, if you
are trying to increase fertility, you are likely not taking any oral contraceptives.
In order to get the best results from this course of treatment, you will need to
take vitex for a minimum of three to six months.
Most women report noticeable
results around the fourth month or menstrual cycle of taking this supplement. Vitex
can be taken for up to 18 months continuously.
It is important to obtain Vitex
in a supplement that is as close to natural as possible. Many so called supplements
on the market contain very little active ingredient or actual herb extract, so
you will need to examine and read labels very carefully.
a better hormonal balance and eventually, inducing ovulation can be achieved, with
this supplement. The key to becoming pregnant is ovulating and having a regular
monthly period and menstrual cycle. You can achieve this regularity with the vitex
fertility treatment option.
