Frequent ejaculation does not speed up pregnancy, but can cause infertility. For patients with fertility requirements, it is best to have sex 2-3 times a week if they are between the ages of 20-30. If they are 30-40 years old, twice a week or once every 5 days or so. If a patient is over 40 years old, it is better to have sex twice a week or once a week, so instead it is easier to get pregnant and also good for sperm production and improvement, because sperm is produced at any time, but it takes generally 3-5 days for it to accumulate to a certain value in the epididymis or seminal vesicles, and about 5 days for the production of seminal plasma, so it is better to give the body some rest time after each ejaculatory cycle. If a person’s sperm count is low and vitality is relatively normal, but sex is too frequent, it will instead make the density of sperm lower and pregnancy more difficult, as the saying goes, if you want it fast, you can’t get it.
