Could Severe Menstrual Pain Be Adenomyosis? Discussing Surrogacy in Mexico and Fertility Planning

When menstrual pain becomes so severe that it interferes with work, menstrual bleeding becomes heavy enough to raise concerns about anemia, or several days each month are spent enduring pain, many women begin to realize that these symptoms may be more than just a matter of having a “sensitive constitution.”

What Is Adenomyosis, and Why Can It Cause Unbearable Pain?

Adenomyosis occurs when tissue similar to the uterine lining is found within the muscular wall of the uterus. As the menstrual cycle progresses, this tissue may cause thickening of the uterine muscle, enlargement of the uterus, and localized inflammatory responses, potentially leading to painful periods, heavy menstrual bleeding, prolonged periods, or persistent pelvic pain. Some patients may also experience pain during sexual intercourse, while others have few or no noticeable symptoms.

It is important to note that adenomyosis and endometriosis are different conditions, although they can occur together. The severity of the condition cannot be determined by pain alone. Whether other gynecological problems are present must be assessed comprehensively based on examination results.

Ms. Lin is 36 years old and has a demanding job. She had always considered her severe menstrual pain normal. Over time, her periods became longer and her menstrual flow increased significantly. She eventually had to take time off work during each period to rest. After an examination, her doctor suspected adenomyosis and arranged imaging tests to further assess her uterus.

The pain was not Ms. Lin’s only concern; she was also worried about her fertility plans. She and her partner hoped to have a child of their own but were concerned that her uterine condition might affect her ability to become pregnant. Her doctor explained that adenomyosis does not necessarily mean natural conception is impossible, nor does it mean a miscarriage is inevitable. However, some studies suggest that the condition may be associated with lower success rates in fertility treatment and certain pregnancy risks. The actual impact varies from person to person.

Ms. Lin then began discussing treatment goals, ovarian function, the possibility of embryo development, and whether her uterus was suitable for pregnancy with her doctor. She also learned that surrogacy could be considered if a thorough evaluation indicated that carrying a pregnancy herself would pose significant risks.

How Is Adenomyosis Diagnosed and Treated?

Diagnosis typically involves evaluating symptoms, conducting a gynecological examination, and reviewing imaging results. Transvaginal ultrasound is commonly used as an initial examination. If the ultrasound results are inconclusive or the doctor needs to assess the extent of the condition in greater detail, a pelvic MRI may also be recommended. If abnormal bleeding is present, the doctor may also evaluate the patient for iron deficiency or anemia.

Treatment depends on the severity of pain and bleeding, the patient’s age, whether pregnancy is planned, and the patient’s preference regarding uterine preservation. Medication may help relieve pain or reduce menstrual bleeding. Some patients may also receive hormonal treatment or other targeted therapies. Those planning to have children should discuss with their gynecologist, before starting treatment, how it may affect ovulation, the timing of conception, and subsequent fertility arrangements.

For intended parents considering surrogacy in Mexico, early planning should also include an assessment by a fertility center, arrangements for embryo creation and transfer, legal consultation regarding surrogacy, and procedures related to parentage and documentation after birth. Adenomyosis may complicate fertility planning, but a diagnosis does not automatically mean losing the opportunity to become a parent.
