- Fibroids: One of the most commonly known reasons behind a bulky uterus is fibroids. Fibroids are non- cancerous tumors that are like little lumps or bulges. They are found along the lining of the uterus, as well as into uterine cavity and very common in women between the ages of thirty & forty.

How does a bulky uterus affect chances of conception?
Fibroids are found in around 20% of women of reproductive age group but all fibroids do not affect fertility. Few might affect fertility by following mechanism:
- Blocking ascend of sperms from vagina.
- By blocking tubal opening.
- Disturbed blood supply to uterine cavity.
- Few fibroids can even lead to miscarriages and preterm birth.
- Commonly the diagnosis is suspected by pelvic examination, when doctors find that uterus is larger than expected. It is then confirmed by a Trans- Vaginal Ultrasound (TVS).
- Not all fibroids affect fertility. Many patients with fibroids conceive naturally
- Decision to treat a fibroid is taken after considering number, size & location of fibroids.
- Large fibroid causing pain, pressure symptoms or abnormal bleeding needs removal irrespective of its location.
- Sub- mucous fibroids are the ones that are near inner lining (endometrium) of uterus. These fibroids distort the uterine cavity and can cause complications in pregnancy also, so should be removed.
- Small fibroids, far away from the uterine cavity can be left untreated.
- Most of the fibroids can now a days be removed by endoscopic surgeries, either laparoscopy or hysteroscopy depending upon location of fibroids.
- Very rarely, an open surgery in the form of laparotomy might be needed for fibroid removal, especially if the fibroid is very big.
- For adenomyosis, unfortunately there is no permanent cure. However, few medicines can temporarily decrease the severity of adenomyosis & help a women to conceive.
