Male fertility includes producing enough healthy sperms, their transportation with semen, and it also needs the right temperature of the scrotum to carry healthy sperms.
Some of the leading causes of infertility are:
Sperm disorders
The most common problem associated with male infertility is sperm disorders. These are:
• Decreased sperm count (oligospermia
• Inability to produce sperms
• Sperms may not be grown fully
• The failure of the sperms to move the right way
Sperm disorders can be hereditary or can be the result of bad lifestyle choices. Drug usage, smoking, alcohol consumption, obesity, emotional stress, and depression can result in sperm related disorders. Also, any congenital disability or damage to the reproductive system may result in low sperm count.
Varicoceles
Varicoceles are swollen veins of the scrotum that causes infertility. This results due to the blockage of blood flow to the scrotum, leading to difficulty in temperature regulation. The warm temperature does not favor the production of sperms resulting in low sperm count.
Varicocele can be treated, which helps to improve sperm number and function, and this may also improve the potential outcome of assisted reproductive techniques such as IVF.
Immunity related infertility
Though it is not a common cause of infertility, sometimes your body creates antibodies that attack your own sperms. These antibodies affect the functionality of sperms, which makes it difficult for them to fertilize the egg.
Ejaculation issues
During orgasm, if semen enters the bladder instead of going out through the penis, it is called retrograde ejaculation. Various health problems can cause retrograde ejaculation, such as surgery, medication, spinal injuries, or diabetes. Generally, in retrograde ejaculation sperm count is normal and can be retrieved and used for assisted reproductive techniques.
Blockage of sperm transporting tubules
Some defects can block the tubes that carry sperms. This blockage can occur due to repeated infections, injury due to surgery, swelling, or it can be an inherited condition. This blockage can prevent the sperm from leaving the body for fertilization.
Hormonal Imbalance
Any hormonal abnormality affecting the hypothalamus, pituitary, or adrenal glands can cause infertility. The inability to produce an adequate amount of testosterone can lead to a reduced number of healthy sperms.
Chromosomal defects
An inherited disorder can result in abnormal development of male reproductive organs. Some of the genetic syndromes causing infertility are Klinefelter’s syndrome, Kallmann’s syndrome, or cystic fibrosis.
Medications
Certain medications can impair the function, structure, and production of sperms. Long term use of steroids, cancer medication (chemotherapy), antifungal medications, and medications advised for arthritis and depression can cause infertility.
Environmental causes
Overexposure to industrial chemicals, heavy metals, or radiation may contribute to your reduced sperm count. Increased scrotal temperature due to tight underpants can also be the reason for infertility.
Lifestyle choices
Tobacco smoking or drinking alcohol can lead to erectile dysfunction or decreased sperm production. Usage of drugs like marijuana or cocaine can reduce the quality and production of your sperms. Emotional stress and depression can lead to sexual dysfunction. Excessive weight or obesity can also be the reason for infertility.
