Safe period adds external ejaculation, is such safe

Ejaculation is a common contraceptive method. Whether it is safe to ejaculate during the safe period or not needs to be judged according to the specific situation.

The safe period method is based on the theory of the female menstrual cycle and calculates the safe period of the menstrual cycle to carry out contraception. If the female menstrual cycle is relatively regular, no eggs will be released during the safe period and no fertilized eggs will be formed. At this time, the safe period plus ejaculation is relatively safe. If a woman's menstrual cycle is irregular, eggs may be discharged during the safe period. Even if in vitro fertilization is carried out, sperm and eggs will combine to form fertilized eggs. At this time, it is not safe to add in vitro ejaculation during the safe period.
