Patient's question:
I had a child once, but later when I wanted another one, I couldn't get pregnant.Doctor's answer:
1. Artificial abortion, medication abortion: Induced abortion and medication abortion are the main causes of secondary infertility. As the number and frequency of artificial abortions increase, the number of women suffering from secondary infertility also rises. Unregulated clinics for induced abortion have become a major factor or cause of secondary infertility. Improper abortion procedures may damage the endometrium, leading to amenorrhea or reduced menstrual flow, or may cause endometritis, preventing the implantation of a fertilized egg and resulting in secondary infertility. Improper abortion can also cause adnexitis, leading to blocked fallopian tubes or hydrosalpinx, which may result in secondary infertility.2. Immunological infertility: Individuals with a history of pregnancy and induced abortion are more prone to developing antisperm antibodies and anti-endometrial antibodies, leading to immunological infertility.
3. Ovarian dysfunction: Some patients with secondary infertility are older and have impaired ovarian function, which may manifest as irregular menstruation, poor follicular development, and ovulation disorders.
