Specification

DESC:FIELD
The present disclosure relates to herbal compositions.
DEFINITION
As used in the present disclosure, the following term is generally intended to have the meaning as set forth below, except to the extent that the context in which it is used indicates otherwise.
Oligospermia: The term “oligospermia”, also known as oligozoospermia refers to semen with a low concentration of sperm. The World Health Organization (WHO) classifies sperm counts at or above 15 million sperm per milliliter (mL) of semen as average. Anything below this count is considered low and is diagnosed as oligospermia.
BACKGROUND
The quality of semen is of vital importance for the reproduction of both humans and animals. Many couples have difficulty in conceiving a child, which primarily can be due to infertile or sub-fertile males. A low sperm count, also known as oligospermia, is one of the major causes resulting in infertility in males. Male infertility may be caused by abnormalities in the testes or other areas of the male reproductive tract, as well as immune system defects. Yet the most common cause of male infertility is disordered sperm production. This happens due to poor or insufficient semen quantity and/or quality. In many of these cases, causes of infertility are treatable. Nutritional and lifestyle changes should be the first step to increasing chances for conception. Smoking and caffeine, drug and alcohol consumption, environmental toxicants, and stress are related to infertility in men and women.
Generally, a total sperm count of less than approximately 15 million, with adequate motility and morphology, is considered to be a low sperm count, and males exhibiting such characteristics are considered to be sub fertile or oligospermatic. Both the quality and the quantity of the sperms are influenced by numerous factors. Various environmental stresses (pollutants, heavy metals, etc.), stressful lifestyle factors (such as nicotine, alcohol, etc.) and changed circumstances of life (marked stress) nowadays place a burden on sperm development as well as on motility, appearance and number of sperm. Sperm production is a very complicated and biologically effortful process, which occurs over a period of several weeks and can easily be influenced in a negative manner.
Existing compositions for improving the sperm count are known. But most of them contain metals or minerals which have toxic side effects.
There is, therefore, felt a need to provide an herbal composition devoid of any toxic side effects for increasing sperm count.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
It is an object of the present disclosure to ameliorate one or more problems of the prior art or to at least provide a useful alternative.
An object of the present disclosure is to provide an herbal composition which has spermatogenic properties.
Another object of the present disclosure is to provide an herbal composition which is devoid of any side effects and is non-toxic.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY
The present disclosure provides an herbal composition comprising extracts from various plants. The composition comprises Mucuna pruriens, Tribulus terrestris, Asparagus adscendens, Anacyclus pyrethrum, and Myristica fragrans. In an embodiment, the herbal composition comprises powder of Mucuna pruriens in an amount in the range of 42 % to 48 % with respect to the total weight of the composition, powder of Tribulus terrestris in an amount in the range of 20 % to 28 % with respect to the total weight of the composition, powder of Asparagus adscendens in an amount in the range of 8 % to 16 % with respect to the total weight of the composition, powder of Anacyclus pyrethrum in an amount in the range of 8 % to 16 % with respect to the total weight of the composition, and powder of Myristica fragrans in an amount in the range of 3 % to 9 % with respect to the total weight of the composition.
The composition of the present disclosure is effective in increasing the sperm count in individuals suffering from oligospermia.
DETAILED DESCRIPTION
Oligospermia is also known as a low sperm count or oligozoospermia. Oligospermia is one of the main causes of male infertility or sub-fertility. Sub-fertility is a reduced ability to achieve a pregnancy. Oligospermia can be the result of many factors, some are permanent and some are reversible. A decrease in sperm production is another cause of oligospermia. This can be due to such conditions as varicoceles, hormonal disorders, diseases of the testicles, and obesity. Other causes of oligospermia include stress, smoking, drug or alcohol use, some medications, exposure to some toxins, malnutrition, and being underweight.
The present disclosure envisages an herbal composition that is effective in increasing sperm count in individuals presented with oligospermia, without any negative side effects.
In an aspect of the present disclosure there is provided an herbal composition.
The composition comprises Mucuna pruriens, Tribulus terrestris, Asparagus adscendens, Anacyclus pyrethrum and Myristica fragrans. In an embodiment, the herbal composition comprises powdered form of the plant parts.

The effectiveness of the herbal composition in increasing the sperm count in individuals presented with oligospermia was demonstrated by the following study.
Healthy males between the ages of 25 to 35 years presented with oligospermia, i.e., having low sperm count (less than 15 million sperm/ml) were included in the study. Most of the candidates had a sperm count in the range of 1 million sperm/ml to 14 million sperm/ml. All the candidates were screened for ailments, such as HIV, active tuberculosis, diabetes, hypertension, Klinefelter syndrome, hydrocele, varicocele, mumps, rheumatoid fever, and sexually transmitted diseases (STDs); and candidates suffering from these ailments were excluded from the study. The study was carried out in 2 stages. In the first stage, 40 candidates were selected for the study and were randomly divided into 2 groups (Group-I and Group-II) containing 20 individuals each. Group-I and Group-II both exhibited a uniform bell curve for the reduced sperm count. The candidates taking part in the study had not taken any medication for oligospermia. All the candidates were told to avoid masturbation for the duration of the study. All the candidates were instructed to take 2 capsules of same color (yellow) daily. The candidates were instructed to take the capsules on an empty stomach, 15 minutes prior to the morning meal. The candidates were advised to take the capsules provided to them every day for 90 days and keep a record of the same. The sperm count was determined on the 0 day (1st day of the study), and thereafter the sperm count was periodically determined every month (after 30 days). The yellow colored capsule of given to Group-I candidates contained the composition (500 mg in each capsule) of the present disclosure. Group-II was the control group and was divided into 4 sub-groups of 5 candidates each. The detail of the composition given to Group-II candidates is summarized in Table-1. Each capsule contained 500 mg of the composition described in Table-1.

*the candidate dropped out after 1 month, and further data is not available. #during the study, the candidate developed viral fever and therefore the study was terminated.
It is seen from Table-2 that there is a significant increase in the sperm count, when the composition of the present disclosure is taken by candidates presented with oligospermia. Further, the increased efficacy of the composition of the present disclosure proves that the ingredients, namely, Mucuna pruriens, Tribulus terrestris, Asparagus adscendens, Anacyclus pyrethrum and Myristica fragrans, exert a synergistic action. This is evident from the increased efficacy of the composition of the present disclosure as compared to the effect shown by the single ingredients in the control group.
Along with the increased sperm count, the candidates in Group-I reported improved vitality, improved sleep, less anxiety, more energy, less routine fatigue. Also, 3 sexually active candidates in Group-I reported better sexual performance and improvement in pre-mature ejaculation. None of the candidates reported any negative side effects.
After the completion of 3 months, the treatment was stopped for all the candidates, and the sperm count for all the candidates was monitored and the result obtained is summarized in Table-3.
