When suffering from ovarian teratomas, it is necessary to undergo surgical removal as soon as possible. For women with fertility needs, it is generally possible to plan for pregnancy three months after the surgery. Ovarian teratomas are mostly benign, and the body can usually recover quickly after the surgery, approximately 2-3 months later, at which point the ovaries generally resume normal ovulatory function. It is recommended that women undergo regular follow-ups at the hospital after the surgical removal, as there is a possibility of recurrence of teratomas. Moreover, it is advisable to schedule intercourse based on the ovulation status.

What are the symptoms of teratoma recurrence?

If a teratoma recurs, in cases of benign teratomas, generally there are no symptoms. Symptoms only arise when the tumor grows large enough to compress the bladder and intestines, which might induce signs of bladder and rectal irritation. Additionally, a teratoma might undergo torsion due to changes in body position, causing sudden lower abdominal pain. If it is a malignant teratoma, there might not be noticeable symptoms early on. The recurrence of a teratoma can only be detected through regular monitoring with ultrasound and tumor markers; there are no better methods available.

What is a teratoma?

Teratoma is the most common type of ovarian germ cell tumor. The majority of these tumors are mature cystic tumors, while a minority are immature solid ones. Mature teratomas are also known as dermoid cysts, are mostly benign, and can occur at any age, mostly between 20-40 years old, often presenting unilaterally. Immature teratomas are malignant tumors, more commonly found in younger patients, and these tumors are usually solid and bilateral. The primary treatment method is surgical, with post-surgery pathology determining the benign or malignant nature of the tumor and guiding subsequent treatment decisions.

Can you get pregnant after removing a teratoma?

Whether a woman can conceive after undergoing teratoma surgery depends on the postoperative histopathological examination. For instance, some women have mature teratomas, which are benign lesions. After the removal surgery that spares the ovarian tissue, menstrual cycles can return to normal, allowing for possible pregnancy. However, if the postoperative pathology results indicate an immature teratoma, which is a malignant condition, further extensive surgery may be required, such as pelvic lymph node dissection or a bilateral salpingo-oophorectomy involving the uterus and its appendages, which might result in the inability to conceive.

Does teratoma affect fetal development?

Teratomas are not normal fetuses; they are a type of tumor originating from germ cells in the ovaries. Pregnancy will not affect the normal development of the baby, and regular prenatal check-ups at the hospital are advisable. If it is possible to surgically remove the teratoma before trying to conceive, it is best to do so. Teratomas can be benign or malignant. Benign teratomas contain various components, including skin, hair, teeth, and bones. Malignant teratomas are poorly differentiated and more prone to malignant transformations and metastasis.

What's the matter with ovarian teratoma pain?

The causes of lower abdominal pain in women with ovarian teratomas are complex. Firstly, as the teratoma grows in size, it can, due to gravity, pull on surrounding ligaments, causing pain on one side of the lower abdomen. When the teratoma is particularly large, it can also compress nerves in the pelvis, leading to neuropathic pain. Moreover, teratomas are heterogeneously textured. If they are quite mobile and not adhering to surrounding tissues, sudden changes in body position, or an increase in uterine size during the mid-pregnancy, might shift the position of the teratoma. This can lead to torsion of the stalk, causing local ischemia and hypoxia, and resulting in acute lower abdominal pain.
