If you have been trying to get pregnant and not having any luck, you may have been researching to try and learn more about why you haven’t conceived, and be confused about the difference between sub fertility and infertility.
What is Subfertility?
Subfertility is popularly defined as a diminished ability to reproduce. Infertility, on the other hand, is defined as an inability to reproduce. So, there is a considerable difference between these two terms because with subfertility, a person isn’t completely infertile.
For most couples, about 80%, pregnancy occurs during the first six cycles with sexual intercourse in the fertile phase. After that, subfertility might loom as a potential problem.
What are the Symptoms of Subfertility?
Generally speaking, if you have tried for at least a year to conceive without success, you may have subfertility.
What Causes Subfertility?
Many things can contribute to subfertility. Here are some of the most common causes of this condition in males and females:
Male subfertility:
- Low sperm count
- Defective sperm production
- Low sperm count
- Lack of sperm
- Inability to ejaculate or problems with ejaculation
- Blocked seminal ducts
- Seminal fluid disorders
Female subfertility:
- Not ovulating
- Blocked fallopian tubes
- Hormonal problems
- Uterus defects
- Cervical mucus defects
In addition, many types of illness or disease may cause reduced fertility.
Subfertility might also result as a complication of another condition, such as:
- Chlamydia
- Salpingitis, or infection and inflammation of the fallopian tubes
- PCOS, or Poly Cystic Ovary Syndrome
- Fibroids in the uterus
Age may also be a factor in female sub fertility. A woman is born with a certain number of eggs, and this supply begins dwindling fairly rapidly after the age of 35.
How is Subfertility Diagnosed?
There are quite a few diagnostic tests to determine if a man or woman has sub fertility. The testing might include:
- Analysis of male semen
- Post coital cervix testing
- Ovulation tests
- Cervical mucous tests
- Hormonal level tests
- Examination of the uterus
- Examination of the fallopian tubes
- Laparoscopy
- Laparotomy
If you want to get pregnant and suspect that you may have sub fertility, you should consult your doctor right away.
