Sperm production or function can be affected by overexposure to certain environmental elements, including: Industrial chemicals. Extended exposure to benzenes, toluene, xylene, herbicides, pesticides, organic solvents, painting materials and lead might contribute to
Sperm DNA damage is the major cause of defective sperm function. DNA damage includes DNA denaturation and sperm DNA fragmentation (SDF) and maybe the common underlying aetiology of infertility, recurrent spontaneous abortion (RSA) pre- and post-implantation losses, accelerated aging, and childhood cancer (1).
excessive alcohol consumption, smoking and using drugs such as marijuana or cocaine. certain medications, including testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), some antibiotics and some antidepressants. being overweight or obese.
There is good news though, as generally any potential damage caused by lifestyle can be reversed, as new sperm are produced on average every 3 months.
Normal sperm have an oval head with a long tail. Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail. These defects might affect the ability of the sperm to reach and penetrate an egg. However, having a large percentage of misshapen sperm isn't uncommon.
If your semen is yellow in colour or there is a foul smell this can be an indication of an infection in your prostate. Infections in the genitals are usually either a urinary tract infection (UTI) or sexually transmitted infection (STI).
Some studies suggest that moderate ejaculation (2–4 times per week) is associated with a lower prostate cancer risk. However, ejaculating more often doesn't mean your cancer risk drops even more.
Eat a healthy diet
Fruits, vegetables, lean proteins, and whole grains are packed with nutrients, fiber, and antioxidants that may improve sperm count and help them swim better (Salas-Huetos, 2019).
Causes of male infertility
Abnormal sperm production or function due to undescended testicles, genetic defects, health problems such as diabetes, or infections such as chlamydia, gonorrhea, mumps or HIV. Enlarged veins in the testes (varicocele) also can affect the quality of sperm.
Men start losing their fertility at age 40.
In a study of more than 1,900 couples, irrespective of the woman's age, IVF attempts involving men 40 or older failed 70 percent more often than IVF attempts involving men younger than 30. Previous theory: Older men produce fewer kids because they get less sex.
Very strong smell: Bacteria and other germs can change the way semen smells. If semen has a foul and overpowering odor or gets worse with time, it may be a sign of an infection or sexually transmitted disease. Sweet smell: Normal semen can smell slightly sweet because of the fructose it contains.
No evidence suggests blocking sperm can cause harm or negative side effects. Unejaculated sperm is not harmful to the body and does not build up. The body reabsorbs sperm that does not leave through ejaculation. This has no side effects on sex drive or fertility.
Oxidative stress produces free radicals which attack the DNA molecule causing breaks in the DNA strands. Sperm DNA damage is often associated with underlying medical conditions (including: varicocele, infection or fever), or certain lifestyle choices (including: drinking, smoking or heat).
There is no way for either of the partners to know if the sperm entered the egg. The only way to know for sure if the sperm did enter the egg is after a positive pregnancy test.
Antibodies in a woman's system can fail to recognize a pregnancy. Or there may be an abnormal immune response to the pregnancy. Women can also develop antisperm antibodies, which attack and destroy sperm.
Sperm DNA damage and miscarriage
Research indicates that sperm with DNA damage can, in some instances, still fertilize an egg. However, this may lead to impaired embryo quality and greater chances of miscarriage. Sperm DNA fragmentation may be caused by: cell death during sperm production.
A: Ejaculating twice a day is not harmful to most men, as long as they are in good overall health. However, frequent ejaculation can lead to a decrease in sperm count over time, which could make it more difficult for a man to conceive a child if he is trying to do so.
That depends on many factors and can vary from time to time. Measured on a stopwatch, it takes an average of 5 to 7 minutes for a man to reach orgasm and ejaculate. But the overall range is wide, from less than one minute to over half an hour.
During sexual intercourse, most men ejaculate between 5-10 minutes and research has shown the average time to ejaculate after penetration is 5 1/2 minutes. Usually, ejaculation less than 1 to 1 1/2 minutes after penetration is regarded as premature ejaculation.
Usually, each millilitre of semen contains millions of spermatozoa (sperm), but the majority of the volume consists of secretions of the glands in the male reproductive organs. It is quite normal for semen to form jelly-like globules and this does not indicate any health or fertility problem.
