Various Causes Behind Infertility

Fertility complications might stem from concerns because of a combination of factors. Fortunately, several safe and effective treatments can significantly improve the chances of becoming pregnant. 

The inability to conceive is the most significant sign of infertility, and there could be no other symptoms or indicators. Infertile women may have irregular or absent menstrual cycles, and men with infertility may exhibit hormonal irregularities, such as hair growth or sexual function changes.

When to see a doctor?

If a woman experiences any of the following symptoms, she should seek medical help as soon as possible.

1. If a female is on or above 35 years, and she has been trying to conceive for six months or more,
2. If a female has crossed the age limit,
3. If there are irregular or missing periods,
4. If women are facing uncomfortable periods,
5. Identified fertility issues,
6. If  diagnosed with endometriosis or pelvic inflammatory disease,
7. Miscarriages for multiple reasons,
8. Cancer treatment has been completed.

A male should consult a professional in the following scenarios:

1. A sperm count that is too low or other sperm-related difficulties,
2. Testicular, prostate, or sexual diseases were treated with cancer in the past,
3. Scrotum enlargement or undersized testicles,
4. Others in your family have difficulty conceiving; it can be genetic.

All steps during ovulation and fertilisation must be done correctly to get pregnant. 

Some infertility issues in couples are present at birth, whereas others appear later in life.

Infertility: Causes

Females

Problems with egg release from the ovaries are known as ovarian abnormalities.

1. Hormonal imbalances, such as polycystic ovarian syndrome, are one of them. Ovulation issues can also be caused by hyperprolactinemia or having too much prolactin – the hormone that controls breast milk production.
2. Excessively high (hyperthyroidism) or excessively low (hypothyroidism) thyroid hormone levels can disrupt the menstrual cycle, resulting in infertility. 
3. Excessive physical activity, food disorders, and cancer are all potential causes. 
4. Uterine or cervical abnormalities, including cervix abnormalities, uterine polyps, and uterus form, can cause infertility in women.
5. Uterine fibroids are benign (noncancerous) tumours that restrict the fallopian tubes or prevent a fertilised egg from implanting in the uterus, causing infertility.
6. A significant cause of fallopian tube damage or occlusion is tube inflammation (salpingitis). This can be caused by a sexually transmitted infection, endometriosis, or adhesions in the pelvis. The ovaries, uterus, and fallopian tubes are affected when endometrial tissue grows outside the uterus.
7. When the ovaries stop operating, and menstruation stops before the age of 40, known as primary ovarian insufficiency –  menopause in its early stages. Immune system disorders, specific genetic conditions such as Turner syndrome or carriers of Fragile X syndrome, and radiation or chemotherapy treatment have all been related to early menopause, although the reason is unknown. 
8. Pelvic adhesions are scar tissue bands that bind organs and can occur due to appendicitis, pelvic infection, endometriosis or surgery to the pelvis or abdomen. This can make women infertile.
9. Certain disorders, most notably reproductive tumours, significantly impact female fertility. Both radiation and chemotherapy can affect fertility.

Males 

1. Because of genetic defects, undescended testicles, health conditions such as diabetes, or infections such as gonorrhoea, chlamydia, mumps, or HIV, aberrant sperm production can occur.
2. Varicocele, or swelling of the veins in the testes, can affect sperm quality.
3. Premature ejaculation, particular genetic disorders like cystic fibrosis, structural abnormalities like a blockage in the testicle, and damage or injury to the reproductive organs can cause sperm distribution problems.
4. Pesticides and other chemicals and radiation can cause overexposure to specific environmental circumstances, which can cause infertility. 
5. High blood pressure and depression and alcohol intake, marijuana, cigarette smoking, anabolic steroids, and antibiotics can all affect fertility.
6. Heat exposure, such as in hot tubs(saunas), can raise body temperature and disrupt sperm production. 
7. Cancer and its treatments, such as chemotherapy, have the potential to cause harm. The effects of cancer treatment on sperm production can be significant, resulting in infertility.

Conclusion

Infertility is characterised by not being able to conceive after a year or more of unprotected sexual activity in either the male or female reproductive system. According to estimates, infertility affects 48 million couples and 186 million people worldwide. Semen ejection problems, sperm absence or low levels, or sperm morphology (morphology) and motility (motility) defects are the most common causes of infertility in men. Infertility in women can be caused by several factors, including issues with the ovaries, uterus, fallopian tubes, and endocrine system.It is always advisable to check with doctors before coming to any conclusion, as medical advancements can help find a way out!
