Adenomyosis is a non-malignant uterine condition characterized by progressively worsening dysmenorrhea, commonly known as severe menstrual cramps. Women affected by adenomyosis experience lower abdominal pain during their menstrual cycles, which can become increasingly severe, negatively impacting daily life and activities. A B-ultrasound examination often reveals uterine enlargement, substantial thickening of the uterine muscle layer, and irregular echoes, all characteristic signs of uterine adenomyosis.

The pathology and physiology of adenomyosis involve the infiltration of endometrial tissue into the uterine muscle layer, leading to pain during each menstrual cycle as this tissue sheds and bleeds. The confinement of this tissue within the uterine muscle layer causes discomfort and pain in the lower abdomen, sometimes reaching intolerable levels. In such cases, surgery, including uterine resection, may be required. Alternatively, conservative approaches, such as using a Mirena intrauterine device or traditional Chinese medicine treatments like Herbal medicine Fuyan Pill, can relieve adenomyosis-related pain.

Adenomyosis primarily impacts fertility through its effects on the fallopian tubes. As endometrial glands and stroma invade the uterine muscle layer, localized or diffuse lesions can develop, affecting the uterine horn. This, in turn, can lead to compression of the fallopian tube openings, causing tubal obstruction and infertility.

Treatment for adenomyosis typically involves medication and surgery, with various options available to address specific symptoms, fertility goals, and other patient considerations.

The question arises: Can women with adenomyosis undergo in vitro fertilization (IVF)?

The answer is affirmative – women with adenomyosis can pursue IVF to achieve conception. There have been numerous successful cases of IVF in patients with adenomyosis. Before commencing the IVF cycle, patients can undergo comprehensive physical examinations, allowing doctors to tailor individualized treatment plans to maximize the likelihood of IVF success.

It is worth noting that adenomyosis can increase uterine contractions, potentially affecting the embryo's implantation rate and, consequently, the success rate of IVF. However, in cases where natural conception is challenging due to adenomyosis, and as long as ovarian function remains robust with normal hormone levels, IVF can be performed with a high probability of success. Even mild to moderate cases of adenomyosis do not typically pose obstacles to IVF.

For older women with severe adenomyosis, the prospects of a successful IVF pregnancy depend on several factors:

1. The severity of adenomyosis can negatively impact the uterine environment. Combined with age-related ovarian function decline and the potential for poor-quality eggs, a woman's psychological state plays a crucial role. Psychological factors can affect hormonal balance, potentially influencing IVF success rates. In such cases, the chance of successful pregnancy may be notably low, potentially less than 10%.

2. However, for some older women with severe adenomyosis, pursuing treatment to enhance uterine and ovarian function under the guidance of a medical professional can significantly improve the chances of a successful IVF pregnancy. In these cases, the probability of pregnancy can increase to around 15%. If these women maintain a stable mental state, the success rate can rise to about 20%.

Several precautions should be considered when undergoing IVF with adenomyosis:

1. Emotional well-being: Maintaining an optimistic emotional state is essential. Excessive stress and anxiety can lead to hormonal imbalances that may hinder embryo implantation. A healthy emotional outlook is vital for supporting the immune system and enhancing the chances of a successful IVF outcome.

2. Uterine warmth: Ensuring the uterus remains warm is crucial, as it plays a central role in embryo implantation. Avoid exposure to cold environments and steer clear of medications with cooling effects.

3. Avoid intense physical activities: Maintaining a comfortable physical state and avoiding exhaustion during the IVF cycle is advisable.

Overall, it is recommended to attempt conception at an optimal reproductive age. If pregnancy does not occur after a year of trying, seeking proactive treatment is advisable. Delaying IVF until later years should be avoided, as advancing age impacts fertility and IVF success rates and increases the likelihood of uterine, cervical, and pelvic abnormalities that can affect pregnancy rates.

In conclusion, adenomyosis is most common in multiparous women aged 30 to 50. However, it can also affect young women, possibly due to various uterine cavity procedures. As a preventive approach, it is advisable to reduce the number of procedures such as dilation and curettage (D&C) and abortion, maintain a healthy lifestyle, and prioritize self-care to reduce the risk of developing adenomyosis.
