Infertility is a condition wherein a woman does not get pregnant in spite of having unprotected intercourse over a period of a year or even more. An abnormal menstrual cycle that is either too short or too long, irregular or even scanty can be an indication of a lack of ovulation, which in turn, is another factor behind female infertility.

Causes

Ovulation disorders are characterized by either a lack of ovulation or irregular and infrequent ovulation. These are a major cause of infertility. This may be due to defects in the regulation of the reproductive hormones by the pituitary gland or the hypothalamus (brain center responsible for producing some of the most essential hormones required by the body). Malfunctioning of the ovary is another cause in itself. Polycystic Ovarian Syndrome, premature failure of the ovaries (a condition wherein a woman s ovaries fail to function properly even before she is 40 years old), hypothalamic dysfunction (a dysfunction of the hypothalamus) and excessive production of prolactin (a hormone that stimulates milk production among women after childbirth) by the pituitary gland are some of the factors responsible for the occurrence of such a disorder.

Damaged fallopian tubes do not allow the sperms to fuse properly with the egg. They might also prevent the fertilized egg from entering into the uterus. This condition may be caused due to pelvic inflammatory diseases (a group of infections of the reproductive organs in women), an infection in the fallopian tubes or the uterus caused due to various Sexually Transmitted Diseases, any abdominal surgery or surgery of the pelvic region and pelvic tuberculosis.

Endometriosis, wherein the tissue that usually grows in the uterus, starts growing outside it, is another factor responsible for infertility.

Several cervical or uterine disorders, such as tumors, inflammation within the uterus, uterine abnormalities, a cervical narrowing or the inability of the cervix to produce mucous for the sperm to travel to the uterus, are likely to impact fertility by obstructing implantation or enhancing the chances of miscarriage.

Treatments

Fertility drugs can be used to regulate and induce ovulation. But they carry with them certain risks and therefore you should consult your physician prior to consumption. Few examples of these drugs are Clomiphene Citrate, Gonadotropins, Metformin, Letrozole and Bromocriptine.

Surgical procedures can be recommended to correct reproductive abnormalities and restore fertility. A laparoscopic surgery or a tubal ligation reversal surgery (a surgery that unites one s fallopian tubes again in order to enable the woman to have a baby) can be advised by the doctor.

Reproductive assistance by Intrauterine insemination (a process that involves putting sperms inside a woman s uterus in order to help her conceive) and Assisted reproductive technology (consisting of IVF and surrogacy).

Infertility - 4 Causes Behind It

While some couples conceive with ease, conceiving a child can be extremely difficult for others. In cases where a woman is not able to get pregnant despite having regular intercourse in tune with her biological cycle, infertility tests may be suggested to investigate the reason behind this. In most cases, these tests are suggested if a year has gone by without intercourse resulting in a pregnancy. Women may also be said to be infertile, if they cannot carry a foetus to full term. 

Infertility can affect both men and women and can be triggered by a number of different reasons. In some cases, it is treatable while in others, alternative ways of having a family may need to be discussed. Hence, it is very important to understand the different types and triggers for infertility and to undergo complete infertility investigations. Some of the common types of infertility investigations are as given below.

Blood tests: A blood test of both partners is used to assess the general health of the couple and to identify any health factors that may be impeding fertility.
Tests for women: 
Hysterosalpingogram: This is an X ray that can identify if a blockage or any other issue in the fallopian tubes are the cause for infertility.
Pelvic ultrasound: This is used to have a look at the anatomy of the female reproductive system and to check for fibroids.
Laparoscopy / hysteroscopy: This is used to get a clearer picture of the ovaries, uterus and other parts of the reproductive system.
Tracking cycle: Ovulation and the thickness of the uterus lining may also affect infertility, This can be diagnosed by tracking and assessing the menstrual cycle.
Tests for men
Semen analysis:This test is used to get an idea of sperm concentration, motility and the appearance of sperm in a man s semen. In some cases, the semen may not include any sperm cells. In such cases, a follow up investigation may be required to assess if sperm cells are being created in the testicles. This is known as testicular sperm aspiration or a testicular biopsy.
Sperm DNA: The DNA in sperm also plays an important role in fertility. This test is used to assess the sperm DNA integrity and to see how it may affect embryo development and chances of an on-going pregnancy.
Infertility treatment depends on the cause identified by the above tests and hence it is important for both partners to undergo complete testing.

Complete Infertility Investigation - Why is It Important?

One of the most important decisions a couple takes is to start a family. It fills them with hope and joy of new future, but if the attempts have been unsuccessful for more than six months, it can take a toll on the relationship and the mental health of the couple. This is the time to seek fertility specialist who will be appropriate to analyze the situation and provide proper guidance. Read on to find out the exact indications to see a fertility specialist:

1. If a woman who is under the age of 35 is unable to get pregnant even after a year of having regular unprotected sex
2. A woman who has had more than three miscarriages
3. Someone who has suffered from blocked fallopian tubes and is in need of surgery
4. One who experiences irregular ovulation
5. A couple who has suffered from genital infections
6. A pregnant woman who has consumed an estrogen derivative
7. A man who has been diagnosed with low semen count, also known as poor motility
8. A couple who has not been diagnosed with any irregularity but is infertile

Which specialist should you visit?

If you or your partner or both have shown signs of infertility, then visiting the following specialists can be helpful:

Specialists for men

Urologists and Andrologists are specialists who treat men for infertility. Urologists conduct an analysis of semen quality, semen count, hormone levels, reproductive organs and abnormalities in bladder and kidneys. Andrologists are medical professionals who specialize in hormonal conditions and physiology of male infertility.

Specialists for women

Hormonal imbalance is one of the potent obstacles to pregnancy. If a general obstetrician/gynecologist has not been able to successfully treat a woman then she can visit a reproductive endocrinologist who specializes in hormonal disorders. Depending upon the nature of the problem, she can also visit a reproductive surgeon who deals with uterine abnormalities, endometriosis, and reproductive organ surgery.

Myths & Facts About Infertility

Infertility is a very common problem among both men and women and it refers to the inability to conceive even after regular unprotected sex. The causes of this can be varied and some of the most prominent ones are:

Causes in Women:

1. Polycystic ovarian syndrome

PCOS is a medical condition in women in which they do not ovulate. It is a major cause of infertility in most women. It can often result in irregular menstruation and an increase in the release of male hormones in the female body. This causes male symptoms like the growth of a beard, hoarse voice etc. in females. The probable causes of this condition comprise being over or under weight, thyroid imbalance etc. It is possible to treat this condition with medical aid and weight management can also prove to be helpful.

2. Lack of sufficient healthy eggs

As you grow in age, the number and health of your eggs decline significantly. This could be a possible reason for your infertility. In this condition, optimizing egg health by maintaining a healthy weight and quitting alcohol and cigarettes can help you get rid of your infertility.

3. Blockage of the fallopian tubes

Blockage of or damage to the fallopian tubes causes the tubal factor that is responsible for infertility in women. The tubal factor can also be a result of endometriosis or any sexually transmitted disease like Chlamydia etc.

Causes in Men:

1. Ejaculatory disorders

Retrograde ejaculation, premature ejaculation, and other issues associated with ejaculation may cause infertility in men. In retrograde ejaculation, the semen enters the bladder instead of emerging out of the penis during orgasm. In premature ejaculation, the ejaculation occurs before the vagina is prepared to receive the semen.

2. Chromosome defects

Disorders like Klinefelter's syndrome can cause abnormal growth of the male reproductive organs resulting in infertility. Other such syndromes include Kallmann's syndrome, Karatagener's syndrome, cystic fibrosis etc. These conditions are mostly genetic.

3. Hormonal imbalance

Male infertility can also be a result of hormonal imbalances like hypogonadism (low testosterone levels), disorders of the testicles, abnormal functioning of the pituitary, thyroid, adrenal and the other glands as well.

6 Common Causes of Infertility That are also Curable

Both women and men suffer from infertility troubles. There are a host of causes that may lead to infertility in men such as lifestyle choices and obesity. Male infertility is characterized by irregular sperm function or reduced sperm count. Infertility has emerged as a common problem as a result of the modern day lifestyle. Extremely hectic schedules, stress, burnout, depression, unhealthy diets; all of these can contribute to fertility issues.

The various reasons for infertility in men are:
1. If you are overweight, then it is time to lose those extra kilos. Obesity leads to a number of health problems, one of them being erectile dysfunction.
2. Various hormonal problems such as complications of the hypothalamus, pituitary and adrenal glands may lead to low testosterone levels in the body.
3. Various infections such as inflammation of the testicles and epididymis that causes blockage of the tubes carrying the sperm can be a cause.
4. Various medications such as using anabolic steroids, antifungal medications and chemotherapy may hamper production of the sperm and thus hit fertility.
5. Both alcohol and cigarettes may cause problems in sperm production, and cause erectile dysfunction. Excessive drinking may lead to complications in the liver resulting in infertility.

The reasons of infertility may range from medical causes to lifestyle choices; some of the causes may be related to the environment. A common cause of infertility is due to problems with transportation of the sperm. These are mainly due to blockages in the tubes that carry the sperm.

Symptoms of infertility in men are:
1. You may experience low libido
2. Your sperm count may be low
3. You may experience lumps or swellings in the testicles
4. Chromosomal complications such as reduced body hair
5. You may have chronic respiratory problems.
