How long does it take from intercourse to pregnancy

It takes a process from having sex to getting pregnant. After having sex, if the sperm and egg can combine, a fertilized egg will be formed, and the fertilized egg will implant. Generally speaking, this time is about 1 to 2 days, because sperm can only survive for 2 to 3 days after entering the female body. If it can meet the egg within these 2 to 3 days, a fertilized egg will be formed. Finally, the fertilized egg will implant, and the whole process takes about ten days.

How long does it take from intercourse to pregnancy

Generally speaking, it takes sperm only a few minutes to reach the fallopian tube from the vagina, but usually takes 1 to 1.5 hours. These sperm that reach the fallopian tubes lose their ability to conceive after three days. When women are in their childbearing years, their ovaries release a mature egg every month. After the egg is released, it is captured by the fallopian tube umbrella and enters the fallopian tube. Within 24 hours after the egg is released, if it encounters sperm in the fallopian tube, the egg will be surrounded by a group of sperm, of which only one sperm can penetrate into the egg and fertilize it. The egg after fertilization is called a zygote. The fertilized egg develops in the fallopian tube and gradually moves towards the uterine cavity. About 7 to 8 days after fertilization, it reaches the uterine cavity and implants into the endometrium, continuously absorbing nutrients and gradually developing into a mature fetus.

The fertilized egg stays in the fallopian tube for 3 to 5 days and then implants in the endometrium. Some are earlier, some are later, and some vary greatly. 3 to 4 days after fertilization, morula is formed, and blastocyst is formed 6 to 8 days after fertilization. Implantation begins 6 to 8 days after fertilization and is completed in 11 to 12 days.

After entering the female vagina, sperm can survive for 2 to 3 days. If ovulation occurs during this period, conception will occur. The lifespan of an egg is about 2 to 3 days, while it takes one day for sperm to travel from the vagina to the fallopian tube, and two days for the fertilized egg to implant. So the time it takes to conceive after sex should be 2+1=3 days.

In medicine, the number of days of pregnancy is generally calculated from the first day of the last menstrual period. If an ultrasound examination is performed, it can generally be seen within 25 to 38 days. However, for some women, due to late fertilization and late implantation, it may take about 40 days to see the result. Therefore, it will not exceed 40 days at the latest.

What are the factors that affect conception?

If you have made all the preparations for conception, but it still doesn't work and you still cannot conceive successfully. This means there is a problem that is affecting your ability to conceive. So, what are the factors that affect conception?

1. Age

There are many factors that affect conception, and the biggest limiting factor for female fertility is age. Generally, the fertility of women over 35 years old decreases rapidly, the miscarriage rate increases, and the sequelae of pregnancy increase.

2. Disease factors

Ovulatory dysfunction - manifested as no ovulation during the menstrual cycle, or although ovulation occurs, the corpus luteum function is not sound after ovulation.

Fallopian tube factors - fallopian tubes that are too long or narrow, fallopian tube inflammation causing blockage of the lumen, water accumulation or adhesions, all of which will hinder the movement of sperm, eggs or fertilized eggs. Fallopian tube disease can account for 25% of female infertility and is an important cause of infertility.
