Introduction

Some women face unexplained difficulties when trying to conceive, even when ovulation and sperm quality seem normal. In some cases, the issue may be a ‘hostile uterus.’ This term refers to uterine or cervical conditions that make it difficult for sperm to survive or embryos to implant. Here’s what you need to know.

What Is a Hostile Uterus?

A hostile uterus refers to an environment inside the uterus—or more commonly, the cervix—that prevents fertilization or implantation. It may involve:

• Thick or acidic cervical mucus
• Inflammation or immune issues in the uterus
• Thin or irregular uterine lining (endometrium)
• Presence of fibroids, adhesions, or polyps

Hostile Cervical Mucus

One common form of uterine hostility involves **cervical mucus** that is too thick or chemically imbalanced, preventing sperm from traveling to the egg. High estrogen levels usually thin mucus to aid sperm movement, but hormonal issues can disrupt this.

Symptoms and Signs

A hostile uterus does not always cause symptoms, but clues may include:

• Difficulty getting pregnant despite regular cycles
• Repeated IVF failures
• Unexplained infertility
• Irregular or painful periods
• Chronic pelvic inflammation or infections

How It’s Diagnosed

• Postcoital test – Evaluates how sperm move through cervical mucus
• Ultrasound or sonohysterogram – Examines uterine shape and lining
• Endometrial biopsy – Tests uterine tissue for inflammation or poor receptivity
• Hysteroscopy – Allows doctors to look inside the uterus for fibroids, scarring, or polyps

Fertility Options for a Hostile Uterus

• IUI (Intrauterine Insemination) – Bypasses the cervix, placing sperm directly into the uterus
• IVF (In Vitro Fertilization) – Fertilizes the egg in a lab and implants embryos directly into the uterus
• IVF with gestational surrogacy – A surrogate carries the pregnancy if uterine environment is not viable
• Surgery – To remove fibroids, scar tissue, or adhesions
• Medications – Hormonal therapy to improve the uterine lining or cervical mucus quality

Can a Hostile Uterus Be Cured?

In many cases, the hostile environment can be managed or corrected with the right treatment. For women with severe uterine issues, gestational surrogacy offers a highly successful alternative to carrying the pregnancy themselves.
