What is male infertility?
Male infertility may be a ill health during a man who reduces the probabilities of his partner getting pregnant.
Approximately 13 out of 100 couples cannot get pregnant with unprotected sex. There are many causes of infertility in men and ladies . in additional than a 3rd of infertility cases, the matter is in man. this is often usually thanks to problems with sperm production or sperm delivery.
What happens under normal conditions?
The body of man produces small cells called sperm. During sex, ejaculation normally transports sperm to the adult female body .
The male genital system produces, stores and transports sperm. The chemicals in your body called hormones control this. Sperm and therefore the male steroid hormone (testosterone) are produced within the 2 testicles. The testicles are within the scrotum, a sac of skin under the penis. When sperm leave the testicles, they enter a tube behind each testicle. This tube is named an epididymis.
Just before ejaculation, sperm pass from the epididymis to a different set of tubes. These tubes are called the ductus deferens . Each ductus deferens leads from the epididymis to behind the bladder within the pelvis. There, each ductus deferens joins the duct from the vesicle . once you ejaculate, the sperm mix with the prostate fluid and seminal vesicles. This forms semen. Then, the semen travels through the urethra and leaves the penis.
Male fertility depends on your body producing normal sperm and delivering them. The sperm enter the vagina of the feminine partner. The sperm travel through your cervix to your uterus to your fallopian tubes. There, if a sperm and an egg meet, fertilization occurs.
The system only works when genes, hormonal levels and environmental conditions are correct.
Causes
Making mature and healthy sperm which will travel depends on many things. Problems can prevent cells from becoming sperm. Problems can prevent sperm from reaching the egg. Even the temperature of the scrotum can affect fertility. These are the most causes of male infertility:
Sperm disorders
The most common problems are with sperm production and growth. The sperm can:
not grow completely
have an odd shape
not move the proper way
be wiped out very low numbers (oligospermia)
it is not done in the least (azoospermia)
Sperm problems are often traits with which you’re born. Lifestyle choices can reduce the amount of sperm. Smoking, drinking alcohol and taking certain medications can reduce the amount of sperm. Other causes of low sperm count include long-term illnesses (such as kidney failure), childhood infections (such as mumps) and chromosomal or hormonal problems (such as low testosterone levels).
Damage to the genital system can cause low or no sperm. Approximately 4 in 10 men with total lack of sperm (azoospermia) have an obstruction (blockage). A congenital anomaly or a drag like an infection can cause a blockage.
Varicoceles
Varicoceles are swollen veins within the scrotum. they’re found in 16 out of each 100 men. they’re more common in infertile men (40 out of 100). They damage sperm growth by blocking adequate blood drainage. it’s going to be that varicoceles cause blood to flow into the scrotum from the abdomen. The testicles are too hot to supply sperm. this will cause a coffee sperm count.
For more information, see the Varicoceles information page.
Retrograde ejaculation
Retrograde ejaculation is when semen recedes into the body. They enter the bladder rather than leaving the penis. This happens when the nerves and muscles of the bladder don’t close during orgasm (climax). Semen can have normal sperm, but semen cannot reach the vagina.
Retrograde ejaculation are often caused by surgery, medications or systema nervosum health problems. The signs are cloudy urine after ejaculation and fewer fluid or “dry” ejaculation.
Immunological infertility
Sometimes, a adult male body produces antibodies that attack his own sperm. Antibodies occur more frequently thanks to injury, surgery or infection. They prevent sperm from moving and dealing normally. We still do not know exactly how antibodies reduce fertility. we all know that it can make it difficult for sperm to swim into the fallopian tubes and enter an egg. this is often not a standard explanation for infertility anymore
