Synopsis
Introduction
A couple is considered to have infertility when they have not conceived after 12 months of having regular unprotected sexual intercourse or 6 months for women over 35 years old. Infertility can be divided into two categories - primary infertility and secondary infertility, based on the couple’s reproductive history.
What is Primary Infertility?
Primary infertility refers to a condition in which couples fail to conceive despite trying for a significant period of time. Couples facing primary infertility often experience difficulty conceiving even with regular, unprotected intercourse.
Causes of Primary Infertility
One of the main reasons for primary infertility is ovulation-related problems. When an egg is not released from the ovary regularly, significant challenges occur with fertilization.
Blocked or damaged fallopian tubes prevent the sperm from getting to the egg, or may prevent the fertilized egg from getting to the uterus. Common reasons for blockage or damage to the fallopian tube include pelvic infections, untreated STIs, or prior abdominal surgery.
Structural abnormalities can stop a fertilized egg from attaching itself to the uterus. Fibroids, polyps, congenital structures, and scar tissue reduce the chances of a successful pregnancy.
Endometriosis occurs when tissue similar to the lining of the uterus is found outside of the uterus. It can lead to the inflammation, scarring, and blockage of reproductive organs, which may make conception difficult to achieve.
An imbalance in oestrogen, progesterone, thyroid hormones, and prolactin can cause irregularities in ovulation and, ultimately, your ability to conceive.
Male Factor Infertility
Male factors can include low sperm count, poor sperm motility, and abnormal sperm shape, all of which can adversely affect a couple’s ability to conceive.
Genetic diseases in men and women may prevent the development of eggs or sperm, prevent or make it difficult to produce a fertilized egg, or make it difficult to develop an embryo after it is produced.
Unhealthy lifestyles may impact fertility and decrease the likelihood of conceiving. Smoking, drinking too much alcohol, poor nutrition, being overweight or obese, and experiencing high levels of stress, may have negative impacts on fertility.
What Is Secondary Infertility?
Secondary infertility is a condition where the couple has a previous pregnancy but is facing challenges getting pregnant again. Although they may have been able to get pregnant before, they are now unable to conceive, creating a challenge that they probably did not anticipate. These challenges lead to significant physical and emotional stress for the couple.
Causes of Secondary Infertility
Women over the age of 35 are known to be at the greatest risk for secondary infertility. Evidence suggests that both the number and quality of eggs decrease, which makes it harder for women to become pregnant even if they have had no problems with a previous pregnancy.
Hormonal imbalances can cause ovulation problems that can affect fertility. Other issues, such as thyroid abnormalities or polycystic ovaries, can also develop later in a woman’s life and will also have an impact on her ability to have another child.
If a woman had complications associated with the previous pregnancy, it can also cause difficulties in having future pregnancies. Some situations may include uterine infections, scarring, and cesarean sections.
The quality of a male partner's sperm can vary over time because of their age, health status, stress levels, and lifestyle choices. A low sperm count or motility can result in difficulty getting pregnant following the first child.
Key Differences Between Primary and Secondary Infertility
| Feature | Primary Infertility | Secondary Infertility |
|---|---|---|
| Pregnancy history | No history of pregnancy | At least one previous pregnancy. (successful or unsuccessful. |
| Onset | Present from the start of trying to conceive | Occurs after a previous conception |
| Common causes | Ovulation disorders, structural abnormalities, genetic factors, and male infertility. | Age, lifestyle changes, and complications from previous pregnancy. |
| Diagnosis | Often diagnosed early when trying to conceive | May be delayed as couples try natural conception again. |
| Treatment Approach | Focuses on identifying underlying reproductive issues from the beginning | It involves assessing changes in health, age, or lifestyle. |
Conclusion
Inability to conceive can result from either primary or secondary infertility. Several reasons can cause either type of infertility, including age, hormonal imbalances, lifestyle choices, and other health conditions. Timely diagnosis of infertility can assist women in dealing with fertility issues and improve outcomes of fertility treatments.
Frequently Asked Questions
Is primary infertility treatable?
Several treatments are available for primary infertility, including medications, modification of lifestyle factors and other assisted reproductive technologies such as in vitro fertilisation (IVF).
Does stress affect fertility?
While stress does not directly cause infertility, it can result in hormonal imbalances that can lead to disruption of normal ovulatory processes and increase the difficulty of achieving a pregnancy.
Does age play a role in causing primary or secondary infertility?
Women’s fertility is greatly affected by their age and significantly decreases after 35 years of age, resulting in both primary and secondary infertility.
At what point should couples seek medical assistance for secondary infertility?
Couples should look for assistance after trying unsuccessfully to conceive for 6 to 12 months, even if they have conceived previously.
Do males experience secondary infertility?
Yes, there is evidence that some men may experience secondary infertility due to their age and lifestyle choices
