Results and discussion
Group A
Fifteen patients were treated by the first regimen, none of
them showed any essential
changes in parameters determining the occurrence of
ovulation. Moreover,
there were noted some undesirable effects such as a longer menstruation cycle,
excessive libido sexualis, related
general excitability, insomnia, and in case of abrupt
discontinuation of the drug intake at the end of the third month or even in reducing the
dose
by 50% only – a dramatic decrease of libido sexualis and general weakness. It made
necessary to apply the second regimen to the
remaining 36 patients – the date are down
in the following figures and tables. The distribution of women treated with Tribulus is given on
Figure 1. The prevailing number of them were in the age group 28 to 30
years old and only 2 were over 36 years of age. Nineteen patients
were with primary
hormonal infertility and 18 with secondary hormonal infertility, i.e. the number
was almost equal, see Figure 2. The
distribution of patients with regard to previous
treatment is shown on Figure 3. One can note that those untreated previously were about
36% of
the women: others with prior hormonal or surgical correction of ovaries were
of almost the same number – 20 to 30% and the
smallest was the group with combined
hormonal and surgical therapy. In Table 1 we show lower values of unsatisfactory
treatment
with Tribulus (33.3%) compared to Clostylbegit (52.4%) or Fertodur (76%).
Undoubtedly best results were obtained with Stimovul
normalized ovulation with
subsequent pregnancy of 39%, normalized ovulation without resultant pregnancy of
35.5% and no effect of 26%.
Tribulus has a considerably more moderate effect: 24 of the
total number of 36 treated women had normalized ovulation but only in 2 of
them
was followed by pregnancy and in 12 patients it had no basic effect. Twenty
women were treated simultaneously with Tribulus and an
ovulation stimulant. The
effect from their combined use was better compared to treatment with single
agents. Probably here there is a
complex effect – hormonal stimulation of ovulation
is combined with increased libido sexualis and improved general and
psyche-emotional
condition of the infertile couple particulary taking into account the fact
that we recommend the use of Tribulus also to the husbands. No side
effects were
observed in the intermittent application of Tribulus.

Group B
The age distribution of the patients in this group is represented on Table
1. Only four of them are younger than 40 years and 2 over 60
years of age.
Eighty percent of all treated women are in the age group 40 to 55.
Twenty six patients were with the natural onset of menopause and the
remaining 24 (48%) – postoperative castration climacteric (Table 2).
The
duration of the menopausal syndrome is shown on Table 3. As seen in a
considerable part of patients the menopause dated back on
the year prior to
therapy with Tribulus. Those were mainly women with postoperative menopause.

Nervous vegetative manifestations were quite frequent with all
treated women. The hot flash was present in 100% of women, sweating in
78%, insomnia
in 82%, and unmotivated superexcitation in 44%.
From the cardiovascular changes, the heaviness in the heart region was
predominant (60%) and changes in the blood pressure and ECG
were observed in
16 women (22%). Libido sexualis was unchanged in only two women (in
comparison with the previous state) greatly
decreased to completely lost
desire for sexual contacts were characteristic to 56% of all patients.
It should be noted that the intake of placebo tablets by 46 from 50 women
did not result in a favorable effect on any complaint

According to the selected signs for classification we established,
complete or almost complete disappearance of all or most of the
symptoms
were found in 49 from 50 treated patients (98%). Only in one woman did Tribulus not have an effect on the menopausal
syndrome and she was
transferred to other treatments. Table 7 shows that in 50% of the treated
women the course of treatment needed
not less than 110 up to 180 tablets to
achieve favorable effect. In 10% of the women this dose was even higher –
190 to 220 tablets. The
average effective doses are given in Table 8 and in
the greater number of women those were more than 100 tablets per course of
treatment.
The effect obtained was retained by a maintenance dose of 2 to 3 tablets a day in 84% of the treated women (Table 9).

The dynamic cytological monitoring of the progesterone – estrogen level
(vaginal cytopreparation) showed that only in 14% of the patients
there was
present a high initial level of estrogen, while in 44% of them it was low or
very low (Table 10).

The variance analysis showed that both the mean values and the confidence
interval are within the limits normal to the age. Comparison of
these data
prior to and after therapy showed that gonadotropic hormones levels
decreased compared to the initial values, while the ovarian
hormones did not
demonstrate such a decrease. There was even an insignificant increase especially in the E2 hormone. These data together
with the clinical picture
can account for the favorable influence on the menopausal complaints and the
considerably enhanced libido sexualis
in two-third of the treated women.
In this case the effect of Tribulus is equivalent, and in some cases even
better than, that of the estrogen-testosterone hormonal preparation
Ambosex
without the adverse side effect of the latter such as virilization and
tendency for weight gain.
Side effect in treatment with Tribulus
Nausea, vomiting, allergy phenomena, and intolerance were not observed. The
preparation is well tolerated. It is worthwhile to note the
fact that after
achieving the desireable effect the abrupt decrease in the effective dose
down to the maintenance dosage results in the sudden
and complete unlocking
of almost the whole menopausal symptom complex. Therefore, the transition
from the effective dose to the
maintenance dose should be gradual and for a
longer period of time.
Conclusion
Our long-term experience with the use of the preparation Tribulus for
treatment of infertility mainly in women, but quite frequently in men as
well, make us recommend it for disturbed gamete formation due to stress
situations, long years of infertile marital life, impaired or almost
missing
libido sexualis, leading to anovulatory menstruation cycles, dyskinetic
changes of fallopian tubes and qualitative changes in the
sperm.
A combination of Tribulus with suitable hormone preparations results in
potentiating its positive effect which explains its use in everyday
practice
for treatment of infertility in the family.
The opinion of the research team, based on the experience from treatment
of more than 150 women with natural or postoperative
menopause, is that Tribulus can successfully be used for treatment of the menopausal syndrome
in women.
Tribulus
Composition: a natural product, obtained from the overground part of the
plant Tribulus terrestris, containing mainly saponins of the
furostanol type
with a predominant quantity of protodioscin (no less than 45%).
Action: non-hormonal preparation which restores and improves
libido sexualis in men, improves and prolongs the duration of erection. It
exerts a stimulating influence on spermatogenesis by increasing the number
of spermatozoa and their mobility. It increases the level of
testosterone.
It improves libido sexualis in women, exerts a slight stimulating
ovulation effect, it has a favorable influence on vasomotory manifestation
during natural and post-castration climacterium, as well as on subjective
complains such as insomnia, general tenseness, irritability or
apathy, etc.
Indication: in men – impotentia coeundi in Klinefelter’s
syndrome, varicocele, Cryptorchism, hypotrophy of testicles, syndrome of
Noonan, sterility on the basis of idiopathic oligoasthenozoospermia
idiopathic azoospermia, varicocele.
In women – endocrinous ovarian sterility, climacteric and post-castration
syndrome with expressed vasomotory and neurasthenic
manifestations.
Contraindication – none
Application: in men – the dosage and duration of treatment are
determined according to the character and gravity of disease. Most often,
the dose is 1 to 2 tablets 3 times a day during meals. The treatment
duration is as follows: in case of impotential coeundi: 40 to 50 days at
least in sterility 70 to 90 days.
In women, the treatment is strictly individual and depends on the gravity
of manifestations. The dose most often used here is also 1-2 tablets
3 times
a day during meals. In cases of sterility the preparation is applied from
the first to the twelveth days of the menstruation cycle. In
postcastration
and climacteric syndrome the treatment lasts 60 to 90 days. After an improvement is obtained the dose is reduced to 2
tablets daily for another
50 to 60 days as supporting dose.
