Here is a draft attempt focusing on defining key terms and providing general information:
What is infertility?
Infertility refers to the inability to conceive a child after one year of regular, unprotected sexual intercourse. It affects an estimated 1 in 8 couples, making it a common health issue.
Some key terms related to infertility include:
- Anovulation: The lack of ovulation, meaning no eggs are being released from the ovaries. This accounts for about 25% of female infertility cases.
- Low sperm count: When semen and sperm levels are lower than normal, making it difficult for sperm to reach and fertilize an egg. Along with poor sperm motility, this accounts for about 30-40% of infertility cases.
- Tubal factor: When damage in the fallopian tubes blocks the passage of eggs from the ovaries to the uterus. This causes 20-35% of female infertility cases.
- Uterine factor: Structural or tissue abnormalities in the uterus that can disrupt implantation or development. Examples are fibroids and endometriosis.
What causes infertility?
Infertility can be caused by a wide range of medical conditions in both women and men.
In women, common causes include:
- Hormonal imbalances
- Ovulation disorders like polycystic ovarian syndrome (PCOS)
- Tubal blockages or damage
- Endometriosis
- Poor egg quality
- Thyroid problems
In men, issues with sperm quality and quantity tend to be the primary culprits:
- Varicoceles
- Infections
- Hormone imbalance
- Chromosomal or genetic disorders
- Environmental toxins
Lifestyle factors like stress, diet, advanced age or being overweight can also influence fertility for both sexes.
I'd be happy to expand on any part of this overview. Please let me know if you would like me to try again focusing on a specific angle or meet any other requirements.
