Infertility in Female Patients

 

Pathological Condition

Definition

Female infertility refers to women's inability to reproduce through the natural and normal methods. Infertility is not the natural status of a healthy adult creature as in humans, it is a case among women who are unable to be pregnant or unable to carry pregnancy to full term.    

It can also be referred to as a disease that affects the reproductive system of women as it makes it fail in achieving the clinical pregnancy after the regular sexual intercourse which is unprotected.

It is also the inability of a sexuality active couple to achieve pregnancy in the time period of one year as this can be referred to the male' infertility by different clinical interventions or from laboratory evaluations for the semen. (Dag and Dilbaz, 2015)

Epidemiological definition of infertility

It is a case of non-pregnancy for women who are at the reproductive age between 15 and 49 and who are at the risk of being pregnant as they don't use any contraception and report not successful pregnancy for two years period or more. (Dag and Dilbaz, 2015)

Primary and Secondary Infertility

Infertility can be either primary or secondary as the primary infertility is when the woman is unable to give birth to a child or even be pregnant while the secondary infertility refers to the woman who is unable to give a second birth to a child and she had one before this inability but currently she is not able to be pregnant.  (WHO, 2017).

Incidence                      

In a research there was a prevalence of infertility estimated with 12.5% (CI 95% 11.7–13.3) among women and 10.1% (CI 95% 9.2–11.1) among men. Increased prevalence was related to later cohabitation with a partner and higher socio-economic status. The reported prevalence of asking for help was 57.3% (CI 95% 53.6–61.0) among women.

There are relationship factors that can be associated with infertility experience as according to the research, infertility may be highest with women who are older age and those who first got married at age 35 or more. It can also be more prevalent among women who were treated from depression for more than 12 months.  (Datta et al, 2016)   

Symptoms

There are many symptoms that should be clear for infertility such as the woemn's inability for being pregnant and having long menstrual cycle that comes every more than 35 days or having a very short one that comes every 21 days or less. This means that the menstrual cycle is irregular and if it is absent too, this means symptoms of infertility as ovulating here is stopped or having problems. There may also be no signs or symptoms of infertility clear on the patient. (Fodina et al, 2016)

When the patient have to see a doctor

When seeking for help may be based on the patient's age as:

·         Up to age 35, most doctors ask them and advise them to try to be pregnant for at least a year before making testing or receiving treatment.

·         If the patient is between 35 and 40, discuss the patient's concerns and signs with the doctor after six months trials.

·         If the patient is older than 40, the patient's  doctor may want to start testing or treatment currently and on time.

If the woman and her husband are well aware of some infertility problems and ask doctor's advice, the doctor will start testing and treatment. This also occurs when the patient suffers a history of irregular or absent menstrual cycle or other relevant diseases and health problems. (Sharma et al, 2015)

Risk Factors

There is a number of risk factors that are associated with infertility in women such as the following ones:

Age

The older women are, the less fertility they have. At the age of mid-thirties, fertility begins to decline at women and this is due to the less eggs amount produced by their ovaries. Another problem is that with age, the eggs' quality decrease and there is a risk of having chromosomal abnormalities in the eggs. There are also risks of birth defects as well as miscarriage in addition to the probability of having different health problems that may affect fertility of women. 

Weight

The women's fat cells produce usually about 30% of the women estrogen that is supposed to be mainly produced in the woman's ovaries and this means that the male hormones that are produced by the women's bodies by the adrenal glands are turned into estrogen. This means that very high weight levels can lead to infertility as a result of the abnormal balance of hormones. Women who are also underweight can have infertility levels because of having low body fat levels while being overweight can lead to infertility due to the above normal fat level and this also include women who are suffering eating disorders such as bulimia nervosa or anorexia and women who suffer very low calories levels due to very strict diets and having irregular periods resulting from such diets. Strict vegetarian women also may have problems with fertility if they lack the needed nutrients and vitamins.    

Smoking

Smoking can be very harmful on the ovaries of women as they can lead to eggs decrease as many studies confirm that there is bigger possibility for infertility among smoking women rather than non-smokers as the smoke is more liable to reach the menopause earlier than in the non-smoker women.  

Alcohol and Caffeine Usage

Infertility is seen to be highly associated with the excessive usage of alcohol and caffeine.

Environmental Factors

There are many environmental hazards that may passively affect the levels of fertility in women such as the industrial solvents, pesticides and herbicides. These substances include chemicals that can be attracted to the estrogen of women  and affect their fertility as well as in men too. These chemical can affect the hormones passively and disrupt them which leads to infertility.

Stress and Fertility

There are different chemical messengers in the women's brains that are called Neurotransmitters and they work in the hypothalamus gland that has great control on the stress and reproductive hormones and this in turn passively affects fertility and hinder infertility treatment. (Shamila and Sasikala, 2011)

Diagnosis

When women are unable to be pregnant in a period of time that exceeds a year of unprotected sex, they have to consult a doctor who is specialist in fertility as the doctor can make the required fertility tests that are very necessary especially when the women are at the age of 35 and more or if the woman has some risk factors related with the case such as weight problems or smoking for example. The doctor may also make analysis for the men's semen before making the needed tests for the woman. (Patel et al, 2016)

Medical History and Physical Examination

Completing the medical history is a very important step in the infertility work up added to the physical examinations. This includes asking the patient about her history of sexual activities such as its timing, frequency and menstrual history as well as other life activities such as smoking, alcohol usage and consumption of caffeine. The doctor also asks about other medication that is taken by the patient and her emotional health in order to be helpful guides before testing.

Easy Preliminary Steps

Before making any work up related to fertility, there should be some steps to be taken in order to reduce cost and help, they include the following:

           Monitor basal body temperature. This step is very important to decide about the occurrence of ovulation.

           Test the consistency of women cervical mucus.

           urine test for detecting the luteinizing hormone (LH) surges.

Laboratory Tests

There are many laboratory tests that can be made for testing the infertility causes and then to monitor and decide its treatment such as the blood and urine tests for testing levels of hormones and evaluating them. They may include hormonal tests for the reserve of ovarian especially to be made in older women.

Clomiphene Challenge Test

Here the standard fertility drug can be used for testing the ovarian reserve as here the doctor takes measurements for the FSH in the third day of the cycle. This is done by giving the woman oral clomiphene on the fifth day and ninth of the cycle, then the FSH of the women is measured by the doctor on the tenth day. If the FSH levels are high on third or tenth days, this means there is low chance for good results.

Tissue Samples

Tests for Autoimmune Disease.

Examples of possible results can include:

           High follicle-stimulating hormone (FSH), luteinizing hormone (LH) levels and low estrogen levels suggest premature ovarian failure.

           High LH and low FSH may say that there is polycystic ovary syndrome or defect in the luteal phase.

           High FSH and high estrogen levels on the day three of the cycle predict means there are poor success rates in older women who are trying fertility treatments.

           LH surges indicate that there is ovulation.

           Prolactin levels and thyroid function should be measured as such hormones can affect fertility in an indirect way.

Special Considerations for Patients with Cancer

Women who suffer cancer and are under treatment of it and in need for being pregnant have to seek the consultant of a reproductive specialist who can make a discussion with them about their options. There can be a fertility preservation method for providing them with the best chances for success in the fertility such as the embryo cryopreservation as this method depends on harvesting the eggs of women and then making the needed vitro fertilization and after that to freeze the embryos for being used later.  (Waimey et al, 2015)

Causes

There could be many causes for infertility and the following medical conditions can be among them as they are able to damage the fallopian tubes and makes problems with women ovulation as well as causing some hormonal complications for them.

     Pelvic inflammatory disease

     Premature ovarian failure

     Uterine fibroids

     Endometriosis

     Polycystic ovary syndrome

There are many causes for infertility in women that are related to medical conditions such as the following ones:

           Ovulation problems

           Blocked fallopian tubes

           Structural problems in the reproductive system

           Problems with quality of cervical mucus or eggs

Ovulation Problems

Ovulation is the process of releasing the egg and it happens in the time of the menstrual cycle that occurs every month. The most known causes of infertility are the hormones that are involved into ovulation such as the Polycystic Ovarian Syndrome (PCOS) as women who have PCOS are not able to regular ovulation and they suffer menstrual cycles that are absent or frequent.

In PCOS, there are excessive amounts of androgens (male hormones) that are produced by the ovaries, especially the testosterone. Then comes high levels of luteinizing hormone (LH) as a consequence for the high androgen production and also there is low levels of the FSH or the follicle-stimulating hormone. This process prevents the follicles from the production of the mature eggs and this shortage results in swelling fluid by the follicles and forming the cysts. (Agrawal et al, 2014)

Blocked Fallopian Tubes

Sperm can be prevented from fertilization of the egg as it can't reach it when it is blocked in the fallopian tubes and can't travel to the uterus in order to apply the implantation process. There are many conditions when it is blocked there such as the Pelvic Inflammatory Disease which is an infection in the pelvic and the fallopian tubes, Endometriosis. Endometriosis which is a condition where cells which are in line in the uterus growing in other areas outside of the uterus, examples are the ovaries. Uterine or Abnormal Scarring and Uterine Fibroids as they may contain some substances that block the way in the fallopian tubes and sperm can't go reach the eggs.

Other Causes of Female Infertility

There are other possible causes for women infertility such as the following ones:

           Elevated Prolactin Levels:

Prolactin is a type of hormone that is produced into the pituitary gland which is stimulating the development of breast and milk production during the time of with pregnancy. When there are higher levels of that hormone which is referred to as (hyperprolactinemia), ovulation is inhibited.

           Congenital Structural Abnormalities:

Infertility may be caused by Congenital reproductive tract abnormalities as such malformations normally leave its effect on the vagina or the uterus. Women who are born by women who had taken diethylstilbestrol (DES) while they are pregnant are at higher risk of getting problems in uterine or fallopian tube that have relation to infertility. Yet still some women that are already born and having uterine can be pregnant successfully. Some of such problems can be corrected via surgery.

           Cervical Mucus:

 Infertility can also be affected by either low amounts of cervical mucus or bad quality related to cervical mucus. Problems related to cervical mucus can have relation to prior surgeries, certain medication and hormonal imbalances.

           Egg Quality:

The number of women's egg decrease as long as they grow older and this doesn't mean that young women don't have problems with eggs but they may have them too, this can normally be caused by some medical conditions or having impaired ovaries due to some treatments. These treatment may be cancer treatment such as chemotherapy or radiation as they can leave passive effect over the egg development or even damage them.  (Masoumi et al, 2015)

 

 

 

 

 

 

 

 

 

 

 

 

 

Management of the Disease

Treatment

For treating infertility, there are many procedures that should be done at first. It should investigate any other medical condition that may be relevant to the problems of infertility. If this procedures don not stop the infertility problem, there  should be other extra steps such as the following ones:

  • measures of lifestyles: (examples having a healthy weight, stopping smoking, organizing time of the sexual activity considering the ovulation cycle)
  • Drugs to induce ovulation, examples the clomiphene and gonadotrophins usage.
  • Assisted reproductive technologies (ART), examples the vitro fertilization (IVF) (Ezzell, 2016)
