Causes of infertility
Infertility may be due to factors involving either the male or the female. The main causes of female infertility include ovulatory disorders and fallopian tube factors. Ovulatory disorders may result from dysfunction in ovulation, such as changes in the hypothalamic-pituitary-ovarian axis, as well as ovarian diseases, with polycystic ovary syndrome being the most common condition that could lead to ovulatory issues. Fallopian tube factors include blockages or inefficiencies, which can also cause infertility in women. Uterine factors can also lead to infertility, including abnormalities of the uterus, inflammation of the endometrium, polyps in the endometrium, and intrauterine adhesions, all of which can affect the implantation of the fertilized egg and cause infertility. Abnormal cervical mucus secretion, cervical inflammation, and an unusual immune environment in cervical mucus that affects sperm passage can also lead to infertility. Male infertility factors primarily include disorders of sperm production and sperm delivery, which may manifest as abnormalities in semen, shown by the absence of sperm, weak sperm, or low sperm count, all contributing to infertility. Additionally, sexual dysfunctions such as premature ejaculation, anejaculation, and erectile dysfunction can also result in male infertility.
Is ovarian teratoma cancer?
Ovarian teratomas are divided into benign and malignant types. If the teratoma is malignant, then it is a type of cancer. If it is benign, it is not cancer; it is just a tumor. The malignancy of a tumor is not as high as that of cancer. Therefore, it is necessary to determine its pathological type. After removing the teratoma, it should be sent to the pathology department for examination to clearly determine whether it is benign or malignant. For benign teratomas, postoperative follow-up observation is sufficient. However, if the teratoma is malignant, the scope of the surgery should be conducted according to the protocols for ovarian cancer, and chemotherapy is required after surgery.
Can polycystic ovary syndrome be cured?
Polycystic Ovary Syndrome (PCOS) is a reproductive dysfunction accompanied by abnormal glucose metabolism, constituting an endocrine disorder syndrome primarily characterized by persistent anovulation, high androgen levels, and insulin resistance. To address the three main features of PCOS, treatment options include controlling diet and increasing physical activity to enhance insulin sensitivity and reduce levels of insulin and testosterone, thereby restoring ovulation and fertility functions. Oral contraceptives, such as Diane-35, can be taken. Oral administration of Diane-35 acts on the endometrium to inhibit excessive proliferation and regulate the menstrual cycle. To reduce androgen levels, progestogens like cyproterone can be used to counteract high androgen levels. If there is high blood sugar, it is also necessary to improve insulin resistance, which can be treated with medications like metformin. (Medications should be used under the guidance of a physician, and self-medication should be avoided.)
How long does it take for cervical cancer to develop?
The causes of cervical cancer are now clear; it is caused by an infection with the HPV virus. Generally, this virus needs to be carried for more than two to three years before it can infect and develop into cervical cancer. There is a process of carcinogenesis where normal epithelial tissue transforms into cervical intraepithelial neoplasia. If the HPV infection is not treated and continues, it could lead to cervical cancer. Thus, the development process is relatively long, typically requiring two to three years. It is recommended that sexually active women undergo cervical cancer screening to check for any pathological changes in the cervix, including HPV, TCT, and colposcopy examinations.
What causes uterine prolapse?
The most common causes of uterine prolapse can be categorized into three types. The first type is childbirth injury, which is the main cause of uterine prolapse. During childbirth, especially with vaginal surgical assistance or prolonged second stage of labor, uterine prolapse can occur. The second cause is long-term increased intra-abdominal pressure, such as chronic coughing, habitual constipation, prolonged standing, or weightlifting. These factors can contribute to uterine prolapse. The third type involves poor development or degenerative changes in the pelvic tissues. This mainly refers to uterine prolapse due to congenital deficiencies in pelvic floor development. Generally, childbirth injuries are the most common cause.
What are the symptoms of teratoma?
Ovarian teratomas can cause abdominal pain and might even result in sudden abdominal enlargement, often accompanied by symptoms like bloating. Women experiencing these symptoms are advised to seek medical attention promptly. Ovarian teratomas are more commonly found in younger women, particularly during their reproductive years. Thus, female patients experiencing these symptoms should promptly undergo an ultrasound at a hospital to check for the presence of teratomas and also have a blood test for tumor markers. If a teratoma is present, it is recommended to undergo surgical treatment as soon as possible due to the risk of malignant transformation.
Can vulvar inflammatory swellings heal by themselves?
If the vulva has only developed an inflammatory lump, it can be cured because as the inflammation subsides, the lump may gradually shrink and fall off. However, it is crucial to determine whether a vulvar lump is inflammatory or malignant. Therefore, patients with vulvar lumps may need to have a biopsy of the vulvar tissue sent to the pathology department to determine its origin. For inflammatory lumps, topical application of erythromycin ointment can be used; it can heal on its own. (Please use medication under the guidance of a doctor.)
Endometrial cancer requires chemotherapy.
If endometrial cancer has high-risk factors, chemotherapy is needed after surgery if these high-risk factors are found in the pathological staging. If it's early-stage endometrial cancer without these high-risk factors, chemotherapy might not be necessary after surgery because chemotherapy also serves to prevent recurrence and metastasis. Therefore, it is advised that patients with high-risk factors in endometrial cancer undergo chemotherapy. Although chemotherapy may have significant side effects, it can improve the survival time and quality of life for cancer patients. The decision to proceed with chemotherapy should be based on the postoperative pathological staging, biopsy results, and the presence or absence of factors like lymph node metastasis.
Does teratoma require blood tests?
If a patient with a teratoma needs to undergo a blood test, the blood test may include routine blood work and blood biochemistry, as well as tumor marker tests such as CA125 and alpha-fetoprotein (AFP) to check for any abnormal increases. If surgery is required for the patient, there might be additional blood tests conducted, including lipid profile, thyroid function tests, and infection and immunity tests. All these require blood draws for the examination.
What tests are done for endometriosis?
For patients with endometriosis, it is recommended that you undergo a gynecological ultrasound examination to observe the condition of the ectopic endometrial tissue in the pelvic cavity, whether it is present on the uterus or ovaries, and whether it has grown on the abdominal wall. Therefore, it is advised to have a gynecological ultrasound examination and a gynecological exam. Patients with endometriosis can also have a blood test for tumor markers. If you wish to undergo additional tests, you can also have a cervical cancer screening, which is also possible. The main recommendations are the first three: the gynecological exam, gynecological ultrasound, and tumor marker tests. These examinations are advisable. If the endometriosis is very severe and the pain is quite intense, treatment may be necessary.
