Ultrasound examinations did not find ovarian volumes greater than 10 ml and follicles with diameters of 2 to 9mm, with at least 12 present.

Can uterine bleeding cause infertility?

Uterine bleeding can be normal or abnormal. Normal uterine bleeding refers to menstruation, which does not lead to infertility. Lack of uterine bleeding may indicate abnormal endocrine function, which could potentially cause infertility. However, if uterine bleeding occurs at times other than menstruation, it is considered abnormal uterine bleeding. There are various causes for abnormal uterine bleeding, and it can affect pregnancy. The most common reason for abnormal uterine bleeding is hormonal imbalance, which leads to irregular ovulation and may result in infertility.

What are the symptoms of infertility?

There are many causes of infertility, so depending on different reasons, the clinical manifestations also vary. For instance, some women suffer from infertility due to abnormal ovulation, which could manifest as abnormalities in the menstrual cycle such as prolonged absence of menstruation, like in polycystic ovary syndrome, or irregular vaginal bleeding. Some women have uterine factors that cause infertility, such as common post-multiple intrauterine operations leading to intrauterine adhesions, where a woman might experience reduced menstrual flow or even amenorrhea, accompanied by painful menstruation. Additionally, infertility in some women might be due to cervical factors, possibly presenting with thick vaginal discharge, contact bleeding, or blood-tinged discharge. Partially, some women might have ovarian endometriomas, which can cause severe painful menstruation and increased menstrual volume, among other symptoms.

Does taking contraceptive pills cause infertility?

Contraceptives are categorized into short-acting, long-acting, or emergency contraceptives. Commonly, long-acting contraceptives, such as those taken orally once a month, have significant side effects. Prolonged use can lead to menstrual irregularities, facial pigmentation, hyperpigmentation, and amenorrhea. Therefore, long-term use of long-acting contraceptives may result in decreased ovarian function, leading to infertility. Generally, emergency contraceptives and short-acting contraceptives have relatively minor side effects. Occasional use does not have a significant impact, but prolonged use can cause menstrual disorders and hormonal imbalances, which in turn can lead to infertility. Thus, contraceptives are not suitable for everyone, and it is not recommended for women who have never given birth to use oral contraceptives for contraception.

How long does it take to be considered infertile when trying to conceive?

Pregnancy for women requires a certain amount of time to be successful, and if one cannot become pregnant in the short term, it does not necessarily mean infertility. It could be due to irregular ovulation or incorrect timing of sexual activity. In clinical practice, it is generally considered that if one has been trying to conceive normally without deliberate contraception and still cannot become pregnant after a year, then infertility should be diagnosed. For cases where conception hasn't occurred after a year of trying, examinations should be carried out for both partners to determine if there are any pathological factors. First, the male partner should have chromosome and sperm analysis; Second, the female partner should be checked for chromosomal infections, immune factors, rheumatology factors, etc. After clearly identifying the reasons, interventions should be made as much as possible to guide normal conception.
