When you and your partner are unable to conceive even after 1 year of unprotected intercourse, then you may be having infertility. The incidence of infertility in India varies from 3.9% (for age 25-39 years) and 16.8% (in the age group 15-49 years), according to Who.
Symptoms Of Infertility
The main symptom is the inability to become pregnant, without any obvious symptoms.
What Causes Infertility?
There are many causes of infertility. Male factor is the most common cause of infertility, such as low sperm count or movement abnormality of the sperm and function.
In women, infertility due to the abnormal uterus or fallopian tubes contributes to nearly 10 to 30 percent. Fibroids, polyps, and adenomyosis cause uterus abnormalities. These problems create obstruction and prevent conception ability. Septate uterus leads to a high rate of miscarriage. Due to endometriosis, the fallopian tubes do not function properly.
Causes of male infertility
These may include:
- Abnormal formation or functioning of sperm due to undescended testicles, developmental disorders, diabetes, or diseases such as chlamydia, gonorrhea, mumps, or HIV. Swollen veins can also influence the consistency of sperm in the testicles (varicocele).
- Genital illnesses, such as premature ejaculation, sperm delivery issues; some developmental disabilities, such as cystic fibrosis; medical problems, such as testicular blockage; or impairment or harm to the reproductive organ.
- Overexposure and radiation of some environmental conditions, such as toxins and other chemicals. Fertility can also be impaired by smoking cigarettes, alcohol, marijuana, anabolic steroids, and taking drugs to control bacterial infections, elevated blood pressure, and depression. Frequent sun exposure, such as in saunas or hot tubs, can increase body temperature and can affect the production of sperm.
- Harm associated with and treatment of cancer, including radiation or chemotherapy. Cancer therapy can inhibit the development of sperm, often seriously.
Causes of female infertility
Causes of female infertility may include:
- Ovulation disorders that impair the ovaries’ production of eggs. That includes hormone abnormalities such as the disease of polycystic ovaries. Ovulation can also interfere with hyperprolactinemia, a disorder in which you have too much prolactin, the hormone that activates the development of breast milk. The menstrual cycle may be impaired or infertility may be triggered either by too much thyroid hormone (hyperthyroidism) or too little (hypothyroidism). Other underlying causes may include too much exercise, eating disorders, or tumors.
- Uterine or vaginal anomalies, including cervical abnormalities, uterine polyps, or the shape of the uterus. By blocking the fallopian tubes or preventing a fertilized egg from implanting in the uterus, noncancerous (benign) tumors in the uterine wall (uterine fibroids) may cause infertility.
- Harm to or blockage of the fallopian tube, mostly due to inflammation of the fallopian tube (salpingitis). This may occur from inflammatory pelvic disease, commonly caused by sexually transmitted cancer, endometriosis, or attachment.
- The role of the ovaries, uterus, and fallopian tubes can be impaired by endometriosis, which happens when endometrial tissue expands beyond the uterus.
- When the ovaries cease functioning and menstruation stops before age 40, predominant ovarian insufficiency (early menopause). Though the cause is always unclear, early menopause is associated with certain causes, including disorders of the immune system, certain genetic conditions, such as Turner syndrome or carriers of Fragile X syndrome, and treatment with radiation or chemotherapy.
- Pelvic adhesions, scar tissue bands that connect organs that may develop after pelvic infection, appendicitis, endometriosis, or pelvic or abdominal surgery.
- Cancer and its therapy. Certain cancers also impair female fertility, particularly reproductive cancers. Fertility can be impaired by both radiation and chemotherapy.
Investigations For Infertility
Semen diagnosis, along with total physical examination, entails infertility analysis for males. If there is no abnormality seen, then the female’s assessment is completed. A PAP smear test is recommended to rule out pregnancy complications due to cervical cancer, sexually transmitted infection, or some other problem. The pattern of ovulation is determined by investigating the levels of hormones. To search for the reproductive organs, an x-ray and ultrasound of the abdomen may be recommended. Ovarian reserve (number of eggs) is evaluated by ultrasound and blood investigations.
If you fulfill any of the following conditions given below, then consultation with the doctor is very important:
- If age more than 35 with the inability to conceive for more than six months
- If age is more than 40 years
- Problem with irregular or absent periods / painful periods
- Diagnosed with fertility problems
- Previous history of miscarriages
Men should talk to a doctor if they have:
- Low sperm count
- History of sexual problems
- Previous treatment for carcinoma
- The size of testicles is small
- Scrotum is swollen
- Familial history of infertility
- IUI (intrauterine insemination): During the time of ovulation, sperm from the partner is directly put inside the uterus of the woman.
- IVF (in vitro fertilization): The sperm from the male and the egg from the female are collected and in a laboratory setting, together are grown for a period of 3-5 days. After this period, the laboratory-grown embryo is implanted into the uterus.
- GIFT (gamete intrafallopian transfer): The sperm and the egg are collected and directly put into the fallopian tube immediately.
- ZIFT (zygote intrafallopian transfer): The fertilized egg (in a laboratory) is put into the fallopian tube at 24 hours.
