For some women, their follicles will shrink instead of being discharged normally after growing to a certain size. There are many reasons for the shrinkage of follicles, such as abnormal endocrine system in women, long-term mental and emotional instability, and many other reasons. 1. What is the cause of follicular atrophy? 1. Endocrine disorders. Endocrine disorders in women lead to insufficient hormone secretion, which prevents the follicles from developing and growing, resulting in symptoms of follicle atrophy. The follicles are unable to ovulate, leading to female infertility. 2. Ovulation disorders: Female luteal insufficiency, endometriosis, pelvic inflammatory disease and other diseases can cause female ovulation disorders. The follicles cannot be discharged, causing the follicles to atrophy. 2. The process of fertilized egg implantation is as follows: 1. Positioning: The zona pellucida disappears before implantation, and the late blastocyst contacts the endometrium with its inner cell mass. 2. Adhesion: After the late blastocyst adheres to the endometrium, the outer layer of trophoblast cells is the syncytiotrophoblast layer, and the inner layer is the cytotrophoblast layer. 3. Invasion: Syncytiotrophoblasts secrete proteinases to dissolve endometrial cells, stroma and blood vessels, completely bury themselves in the endometrium and are covered by the endometrium. 3. What does it feel like when the fertilized egg implants? 1. Feeling nauseous. Some people begin to experience symptoms of morning sickness in the first few weeks after conception. You may feel nauseous or queasy. Although morning sickness is also called "morning sickness," queasy symptoms are not limited to the morning. You may feel nauseous and want to vomit all day and all night. 2. Breasts become softer. If your breasts feel tingly, tender, and swollen, you may be pregnant. This symptom may appear within the first few days after conception. After your body adjusts to the influx of hormones, this pain will subside and your breasts will no longer feel uncomfortable. 3. Feeling tired. The surge in progesterone (a hormone) can make you feel exhausted. Almost all pregnant women suffer from this symptom, and you can observe other symptoms to confirm your suspicion. |
