The occurrence of natural miscarriage is somewhat related to the quality of the male's sperm. When the vitality of the sperm and the rate of sperm abnormalities are both decreased, it tends to lead to miscarriage. The combination of sperm and egg requires both to be healthy to conceive a healthy baby. If the quality of the sperm is poor, it might lead to miscarriage even if a fertilized egg is formed. Therefore, before pregnancy, both men and women should go to the hospital for pre-pregnancy check-ups to see if their bodies are suitable for pregnancy. If the sperm quality is poor, it should be regulated, and pregnancy should only be attempted after the sperm quality has been improved.

What are the symptoms of a natural miscarriage?

What are the symptoms of a spontaneous miscarriage? Spontaneous miscarriage is a process where the embryo is lost from the mother's body. Before diagnosing a spontaneous miscarriage, it is first necessary to confirm an intrauterine pregnancy. After confirming the intrauterine pregnancy, symptoms include abdominal pain and heavy bleeding, which indicate a spontaneous miscarriage. The manifestations of a spontaneous miscarriage primarily include abdominal pain or bleeding, along with the expulsion of necrotic tissue-like material, which is the embryonic tissue. The symptoms are bleeding and abdominal pain. The symptoms of a spontaneous miscarriage are mainly distinguished from an ectopic pregnancy. An ectopic pregnancy can also present similarly, where an ultrasound fails to reveal a gestational sac, accompanied by abdominal pain and bleeding. Such scenarios should be considered for ectopic pregnancy, whereas abdominal pain and bleeding after confirming an intrauterine pregnancy indicates a spontaneous miscarriage.

What to pay attention to during a natural miscarriage?

During the period of miscarriage, it is important to ensure adequate sleep to help the body recover. Additionally, it is crucial to stay warm, avoid cold exposure, and refrain from consuming raw, cold, or spicy foods. Opt for light, easily digestible foods instead, and consider drinking some brown sugar or millet porridge. It is also essential to maintain a good emotional state to facilitate physical recovery. Since women may feel particularly low after a miscarriage, family support and psychological care are important during this time. Moreover, maintaining cleanliness and hygiene in the genital area is necessary; frequent changing of underwear and sanitary pads is advised. A week after the miscarriage, it is advisable to visit the hospital for a follow-up examination.

What is the discharge from a natural miscarriage?

Miscarriage refers to the spontaneous expulsion of the gestational sac from the uterine cavity, without the need for human intervention. Human interventions mainly include medical abortion or painless surgical abortion. During a miscarriage, the gestational sac is expelled from the uterus, so the expelled material is primarily the gestational sac. The sac generally consists of white villous tissue, and during a natural miscarriage, it is essential to identify villous tissue in the pregnancy tissue in order to confirm a natural miscarriage. Besides the villous tissue, due to decidualization changes in the endometrium after pregnancy, the tissue expelled during a miscarriage also contains a certain amount of decidual tissue. Therefore, the material expelled in a natural miscarriage mainly includes the villous tissue, followed by uterine decidual tissue.

How long after a natural miscarriage can one have sexual intercourse?

After a natural miscarriage, it is generally advisable to abstain from sexual intercourse for at least one month. Following a natural miscarriage, there are wounds inside the uterine cavity that need to heal through a restoration process continuously repairing the endometrium. Engaging in sexual intercourse too soon can increase the risk of infection. One month after a miscarriage, with a doctor's guidance and upon confirming that the body has recovered well through examinations, sexual intercourse can be resumed. Within the first month, it is crucial to prohibit sexual activities, including sitz baths and swimming, to reduce the chances of infections. Post-surgery, there should also be appropriate advisement. Both partners must take this matter seriously to avoid impacting future health.

What is lochia after a natural miscarriage?

Vaginal bleeding is a symptom of natural miscarriage, and this is known as lochia. Lochia is the discharge from the vagina after childbirth, typically ceasing about a week postpartum. After a natural miscarriage, normal bleeding lochia generally has a bloody smell but does not have any other odorous scents. Following a natural miscarriage, it is important to monitor the expulsion of lochia, paying attention to its amount, color, and odor changes, as these factors can reflect the recovery of the uterus. Normally, the lochia will clear up around a week, and it should not last longer than two weeks at most. If lochia persists for an extended period after the miscarriage and is accompanied by abdominal discomfort, a hospital visit is necessary for a follow-up to check the condition of the uterus.
