No. By the time a woman is due to menstruate the egg released earlier in her cycle is long dead - typically ovulation occurs 14 days before menstruation, and at most there will only be a viable egg for up to 48 hours after ovulation.
the first menstrual periods is the beginning of the reproductive period of women. this is the time when the first ovulation starts. periods is a cyclical process in which it starts by hormonal changes due to this hormonal changes the ovum is produced from the ovary then it travels to fallopian tube to uterus and it wait for sperm for fertilization during this stage the inner wall of the uterus is thickened to receive the fertilized egg. when the fertilization not happened then the inner thickened layer of the uterus is shed off with the ovum with some blood this is known as periods. this is the process of periods.
For women, the uterine lining sheds, in the physiological term of menstruation. In rabbits, nothing happens. They just keep going in and out of heat until fertilization does occur. The same goes for cows and heifers.
Fertilization can occur if a woman has unprotected sexual intercourse around the time of ovulation, which typically happens about 14 days before the start of her next menstrual period. Sperm can survive in the female reproductive tract for up to 5 days, so conception can happen even if intercourse took place a few days before ovulation.
No, a human female can not be impregnated by canine semen - the genetic differences are too profound for fertilization to occur.
Yes
Women typically get their period monthly as part of the menstrual cycle, which prepares the body for a potential pregnancy. Each month, hormones regulate the thickening of the uterine lining in anticipation of a fertilized egg. If fertilization doesn’t occur, the body sheds this lining, resulting in menstruation. This cyclical process is driven by hormonal changes and typically lasts about 28 days, although it can vary among individuals.
If a woman is having her period, then she cannot be pregnant. Menstruation is a direct result of "failed fertilization", i.e. the egg (ovum) was not fertilized by a sperm cell. Therefore, women stop having their period when they conceive, since fertilization was successful and the production of ova (eggs) has ceased.
Reproduction can occur as soon as you are adolescent, that is the definition of adolescence, when a child is turning into an adult. It happens to different girls at different ages, from 9 to 18, but usually around 11-13. You can get pregnant before a period occurs as you ovulate before a period.
Probably not as the uterine wall breaks down if a pregnancy does not occur and the subsequent period. However there are some women who have a light period the first month of pregnancy.
You could just have a shorter cycle. Some women have a long cycle(over 28days) and some have shorter ones.
Yes, this is normal. Intercourse doesn't effect menstruation at all so it has no relation to your period, when your period starts is dependent on your menstrual cycle - sex doesn't effect this.
Pinpointing when fertilization can occur is difficult because it depends on various factors, including the timing of ovulation, the lifespan of both sperm and the egg, and individual variations in menstrual cycles. Sperm can survive in the female reproductive tract for up to five days, while the egg is viable for about 12-24 hours after ovulation. Additionally, not all women have regular cycles, making it challenging to predict ovulation accurately. These factors create a window of uncertainty around the exact timing of fertilization.
