How soon after induced abortion does the endometrium begin to regenerate?

Under normal circumstances, the endometrium begins to gradually regenerate within 1–2 weeks after induced abortion. Complete recovery to normal thickness usually takes 1–3 menstrual cycles, with the exact duration depending on individual physical condition, gestational age at the time of abortion, and postoperative care. A detailed analysis is as follows:

After induced abortion, the uterus undergoes a process of contraction and involution. Within 1–2 weeks post-surgery, estrogen and progesterone levels gradually rise, stimulating the basal layer of the endometrium to begin proliferating and repairing. When the abortion occurs at an earlier gestational age, endometrial damage is generally milder, allowing earlier initiation of regeneration and faster recovery. In contrast, abortions performed at later gestational ages involve more significant endometrial injury, potentially prolonging the healing period.

Individual constitution and postoperative recovery status also influence endometrial regeneration. Women who avoid infection, maintain adequate nutrition, and follow regular sleep patterns tend to experience faster endometrial repair. However, complications such as intrauterine adhesions or infections can impede endometrial growth and delay recovery. The return of the first menstruation after abortion typically indicates that the endometrium has largely restored its ability to shed cyclically.

After an induced abortion, it is important to maintain genital hygiene and avoid sexual intercourse and tub baths to prevent infection. Nutritionally, a diet rich in protein and vitamins should be emphasized to support endometrial repair.
