Low spe,rm count (oligospermia) is a leading cause of infertility or sub-fertility issues among men. While it requires only one spe.rm to fertilise the ovum, the odds of conception are such that it takes millions of sperm per millilitre of semen to actually achieve the goal of fertilisation. A “normal” spe.rm count is about 20 million or more per millilitre of se.men. Over 60 per cent of the s.pe.rm in each sample should exhibit normal morphology and indicate typical motility – the forward-swimming movement. or low s.pe.rm count is indicated in simple tests that reveal the concentration of sp.er.m in a given sample quantity.

In general, scientists and fertility doctors are noticing a drop in spe.rm count and motility, which makes it harder for couples to make babies. Other factors attributed to this include the following: Drug use Anabolic steroids taken to stimulate muscle strength and growth can cause the te,stic.les to shrink and sp.er.m production to decrease. Use of cocaine or marijuana might reduce the number and quality of your sper.m as well.

Overheating the te,stic.les: Elevated temperatures impair s.per.m production and function. Although studies are limited and are inconclusive, frequent use of saunas or hot tubs might temporarily impair sp.er.m count. Sitting for long periods, wearing tight clothing or working on a laptop computer for long stretches of time also might increase the temperature in your scr;otum and slightly reduce spe’rm production. Drinking alcohol can lower testosterone levels and cause decreased sp.er.m production.

Poor lifestyle Men who smoke might have a lower s,per,m count than those who don’t smoke. Obesity can impair fertility in several ways, including directly impacting sperm and by causing hormone changes.

Plastics
Bisphenol, BPA, a substance in plastics found in many household products, can lower sperm count and motility. A 2008 study in the journal Fertility and Sterility, showed that men with high concentrations of BPA in their urine also had low sp,er.m counts. Food packaging is a major source of BPA which can seep into foods.

Pesticides

Scientists have also noted that farmers are exposed to pesticides that tend to lower their sp,er.m count. The chemicals runoff gets into tap water and can disrupt hormonal processes.

Tumours Cancers and non-malignant tumours can affect the male reproductive organs directly. Surgery, radiation or chemotherapy used to treat tumours can also affect male fertility.

Undescended testicles

During foetal development, one or both testicles sometimes fail to descend from the abdomen into the sac that normally contains them (scrotum).

Chromosome defects

Inherited disorders such as Klinefelter’s syndrome — in which a male is born with two X chromosomes and one Y chromosome instead of one X and one Y — cause abnormal development of the male reproductive organs. Other genetic syndromes associated with infertility include cystic fibrosis, Kallmann’s syndrome and Kartagener’s syndrome.

Celiac disease

A digestive disorder caused by sensitivity to gluten, celiac disease can also cause male infertility. Fertility may improve after adopting a gluten-free diet.

Certain medications

Testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), certain antifungal and antibiotic medications, some ulcer medications and other medications can impair sperm production and decrease male fertility.

Prior surgeries Certain surgeries such as va,sect,omy, inguinal hernia repairs, scrotal or tes,tic,ular surgeries, pr,ostate surgeries, and large abdominal surgeries performed for testicular and rectal cancers might prevent you from having sperm in your ejaculate. In most cases, surgery can be performed to either reverse these blockages or to retrieve sperm directly from the epididymis and testicles.

Environmental causes Spe,rm 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 low sperm count.

Radiation or X-rays

Exposure to radiation can reduce sper.m production. It can take several years for sperm production to return to normal. With high doses of radiation, sp,er,m production can be permanently reduced. It is being reported that keeping mobile phones in the pocket near the upper thigh is extremely dangerous to spe,rm cell production and morphology.

Occupation

Certain occupations might be linked to a risk of infertility, including welding or those associated with prolonged sitting, such as truck driving. However, the data to support these associations are inconsistent.
