Subfertility - What is it and How is it Different From Infertility

If you’re trying to conceive but facing problems, you might have Subfertility issues. In women, subfertility happens for several reasons, such as uterine fibroids, endometriosis, and thyroid. As you age, Subfertility increases, and you may experience delayed pregnancy.

What is Subfertility?

Subfertility refers to the difficulty in conceiving naturally. Couples trying to conceive but don’t succeed are likely to be subfertile. A woman is considered subfertile if she produces eggs after a periodic interval. In some cases, a woman getting pregnant but unable to carry a baby is also considered subfertile. Subfertility also refers to an inability to conceive or a reduction in infertility after a long period of unintended failure to conceive.

How is Subfertility Different from Infertility?

Sometimes infertility and subfertility are often used interchangeably, which is not correct. Infertility refers to the complete inability to conceive. In the case of infertility, one partner has some problem, and the couple cannot get pregnant naturally. On the other hand, subfertility is a medical condition where women or men have some issues, such as tubal disease and sperm deficiency, so their pregnancy is delayed.

Top Causes of Subfertility

Subfertility in women can happen due to various factors, such as:

1. Ovulation Problems

In this condition, the egg doesn’t release from the ovary during the menstrual cycle. This may happen due to polycystic ovary syndrome, thyroid disorders, and premature ovarian failure.

2. Prior Surgery

Sometimes prior surgery of the reproductive tract may damage the fallopian tube and uterus, which results in subfertility.

3. Cervical Mucus Problems

The thick mucus around the uterus cervix can cause Subfertility. Due to thick mucus, sperms are unable to reach the egg.

4. Endometriosis

This is a common condition where the endometrial wall is present outside the lining of the uterus. This may damage the fallopian tubes and ovaries resulting in difficult conceiving.

5. Fibroids

Fibroids are non-cancerous tumors present inside the uterus and fallopian tube. They can block the fallopian tube and prevent sperm and egg from fertilizing, leading to Subfertility.

6. Pelvic Inflammatory Disease

This refers to the fallopian tube, uterus, and ovaries infection. The scarring inside the uterus or fallopian tube prevents sperm from meeting.

7. Medications

Anti-inflammatory drugs, chemotherapy, spironolactone, and mental health disorder medications can lead to subfertility. Some medications can interfere with ovulation, egg production, egg release, fertilization in the long term.

Symptoms of Subfertility

Some common symptoms and signs of Subfertility are as follows:

1. Irregular Periods

The menstrual cycle of women is 28 days. If you are experiencing a menstrual delay or irregularity in menstruation, this could be a sign. Sometimes menstrual irregularity also occurs due to polycystic ovarian syndrome and hormonal issues. Both these factors also lead to subfertility and infertility.

3. Pain During Sexual Intercourse

Some women believe painful sex is common since they have had it their whole lives. Yet it isn’t. It might be connected to endometriosis, hormonal problems, or other underlying diseases causing Subfertility.

4. Missing Periods

Women occasionally experience a bad month, which is common. Your menstruation may briefly stop due to stress or strenuous exercise. But if you’ve had menstruation in months, it’s important to have your fertility evaluated.

Diagnosing Subfertility

The fertility specialists help in diagnosing subfertility. They start with a physical examination that includes a pelvic exam and a genital area examination. For surety, they order several clinical tests to know if women experience Subfertility.

Blood test to monitor hormones level
Transvaginal ultrasound for diagnosing reproductive organ
Hysterosalpingography uses to evaluate the uterus and fallopian tubes condition
Ovarian reserve testing to track the quantity and quality of eggs.

Treatment Options For Subfertility

Subfertility doesn’t mean you cannot conceive for your whole life. Thankfully, many treatment options are available to improve your conceiving odds. Some of the treatment options are as follows:

1. Medications

Treatment with medications depends on the reason behind subfertility. However, doctors may suggest some drugs, such as clomiphene, tamoxifen, letrozole, metformin, cabergoline, and bromocriptine. But keep in mind; never take these medications without consultation with a doctor.

2. Assisted Reproductive Technology (ARTs)

This is one of the common fertility treatments suggested to couples facing problems in conceiving. Some of the common ART techniques are:

a. In-Vitro Fertilization and Intracytoplasmic Sperm Injection

Techniques where sperm is injected into the uterus to meet the egg.

b. Assisted Hatching

A technique that assists embryo implantation by opening the growing embryo’s outer layer.

c. Donor Conception
