According to astrology, if the aspect of Mars is on a weak Venus in a person's horoscope, then this situation can cause blood sugar problems for that person. This can weaken the body and reduce sexual desire. In astrology, the role of Venus is considered important for happiness in married life. If Venus is low or is set and sitting in the twelfth, fourth, and seventh house of the horoscope, then the person faces problems in married life. Such people feel a lack of sexual pleasure due to some reasons.

The human body and Venus: Venus is believed to have the most influence on the eyes, nose, chin, ears, neck, penis, and sperm. If the lord of the first house of the horoscope, i.e. Lagneshwar, is sitting in the seventh house in the horoscope and the lord of the fourth house has a sight on it, then the married life is very good. They also get a lot of material happiness.

Obstacle in getting a child and astrology: If the lord of the seventh house in a person's horoscope is Venus and Saturn and Rahu are also present in the house, then due to the effect of the sight of these two planets, there is a lack of sperm in such a person, which creates obstacles in getting a child.

Astrology and AIDS: If Venus, Saturn, Rahu, and Mars are present in the eighth house along with the lord of the house in the horoscope of a person, then such a person is likely to have AIDS. In such a planetary position, the person should remain restrained and be more cautious about health. Astrology tells about the possibilities which can also be avoided with caution.

Astrology and Sexual Diseases: It is believed that the Scorpio sign affects the genitals of a person. If the Scorpio sign is in the second, sixth, or eighth house in the horoscope of a person and these are influenced by inauspicious planets, then such a person is likely to suffer from sexual diseases.

Gems are also beneficial: A person suffering from sexual disease and infertility due to the bad position of Venus should wear a turquoise gemstone. Apart from turquoise, diamond, zircon, and onyx can also be worn. But it is most important that before wearing any gemstone, you must show your horoscope to a good astrologer.

Do not wear a diamond gemstone for one year after marriage: Diamond is the gemstone of Venus which is becoming more popular in marriages these days. People have started making the bride wear a diamond ring during the engagement. According to astrology, this is not right. This creates obstacles in getting a child.

According to astrology, if the lord of the seventh house in a person's horoscope is Venus and Saturn and Rahu are also present in that house, then due to these two planets there can be a lack of sperms. This can cause problems in having children.

The lack of sperm in men is commonly called impotence or impotence. When the number of sperm per milliliter in a man's semen is less than 1.5 crore, then in medical terms it is called low sperm count.

Some symptoms of low sperm count:
1. Lack of erection
2. Lack of desire to have sex
3. Pain or swelling or lump in the testicular area

Tips to increase sperm count: 

1. Yoga postures: Doing yoga postures like Dhanurasana, Agnisar Kriya, Setubandhasana, Halasana, and Padmasana can improve the quality and motility of sperm.

2. According to astrology, wearing gems like turquoise, diamond, zircon, and onyx can be beneficial. However, before wearing any gem, one should consult a good astrologer.
