Can a pregnancy be sustained if conception occurs despite low sperm motility and survival rate?

Introduction

Pregnancy, also known as gestation, can usually be maintained even when sperm vitality is low. Although low sperm survival rate may affect the likelihood of successful pregnancy to some extent, it does not mean that the fetus cannot be successfully preserved. Low sperm vitality may be caused by various factors, such as poor sperm quality, insufficient quantity, or reduced motility.

Pregnancy, also known as gestation, can generally be maintained even when sperm vitality and survival rate are low. The specific analysis is as follows:

Although low sperm survival rate may affect the likelihood of successful pregnancy, it does not mean that a fetus cannot be sustained once conception has occurred. Low sperm survival rate may result from various factors such as poor sperm quality, insufficient quantity, or reduced motility, all of which could decrease the chances of sperm successfully fertilizing an egg, thereby affecting fertility. However, even with a low sperm survival rate, successful pregnancy is still possible. This is because a woman's egg typically remains viable for only 12–24 hours after ovulation, while sperm can survive within the female reproductive tract for 2–5 days. Therefore, even if the number of sperm is low, as long as some possess adequate motility and fertilization occurs at the right time, conception can still take place. Once pregnancy is established, it can usually be maintained.

It is recommended to attend regular prenatal check-ups and maintain a balanced diet during pregnancy to avoid adverse effects on fetal development.

Will you definitely get pregnant if you have unprotected sex during ovulation?

Under normal circumstances, having intercourse with ejaculation during the ovulation period results in a relatively high chance of sperm meeting the egg, and the probability of pregnancy is also higher. However, it is not guaranteed that pregnancy will occur. Poor follicular development, lack of dominant follicle release, or low sperm motility, dead sperm, or absence of sperm in males can all reduce the likelihood of conception. Blocked or impaired fallopian tubes can prevent sperm from meeting the egg, thus preventing pregnancy.
