Minimum Sperm Count For IVF And Other Essential Requirements
A person is considered to have a normal sperm count if there are 15 to 200 million sperm per milliliter of ejaculate fluid [1]. This sperm count is necessary for successful fertilization and conception.
However, if a person has a lower sperm count than 15 million sperm in semen analysis, he may not be able to conceive naturally. Person should search semen analysis test near me.
In Vitro Fertilization is a technique to achieve conception for men with lower sperm count. According to different studies, the minimum sperm count of IVF is 10 million to 15 million sperm per milliliter of semen [2].
Why Sperm Count Is Important?
Although just a single sperm fertilizes the egg in the female body, a single sperm can’t successfully swim from the cervix all the way to the fallopian tube to reach the egg.
Sperm cells face different challenges in reaching the egg in the female reproductive tract and only a few are able to reach the egg [3]. To pass through all the challenges, there should be a certain number of sperm cells efforting to reach the egg. This number is between 15 million sperms to 200 million sperms per milliliter of semen.
When the sperm count is below 15 million, there may not be enough sperm to reach the egg and cause a successful pregnancy. However, a person with a lower sperm count can achieve conception but has very few chances compared to one with a normal sperm count [1].
What is In Vitro Fertilization (IVF)?
In Vitro Fertilization or IVF is a tool of assistive reproductive technology that helps couples achieve conception [4]. It is very helpful for couples who can’t conceive because of low sperm count or poor sperm motility.
Ever wondered how does IVF works for a man with a lower sperm count?
In IVF for male infertility, the sperm cells are taken from the male partner, and the egg is removed from inside the female partner. Then both sperm and egg cells are fertilized in a lab within the controlled environment and the zygote is formed.
When the development of a zygote starts, the doctors then implant that zygote inside the female uterus and it develops into a baby.
What Is the Minimum Sperm Count For IVF?
IVF treatment is here to help people with lower sperm count to achieve conception but this method also has some minimum requirements.
But how much sperm is needed for IVF?
Studies show that for a successful IVF procedure, the male partner should have a sperm count between 10 million and 15 sperm per milliliter of semen [2].
In other words, a person must have between 35 million and 40 million sperm per ejaculate to benefit from the IVF technique.
What Is the Minimum Sperm Motility For IVF?
Sperm count is not the only thing important for a successful IVF procedure. Sperm motility or the ability of the sperm cells to swim toward the egg is also important.
Typically, sperm motility is considered normal if the ejaculate fluid has at least 40% of motile sperm [5].
For a successful IVF procedure, studies show that a person should have at least 30% of sperm motile in the seminal fluid [2].
Is Sperm Morphology Important For IVF?
Sperm morphology refers to the size of a sperm and shape of the sperm cells within the semen [6]. A sperm cell is considered morphologically normal if it has an appropriately shaped head, midpiece, and tail.
Typically, only about 4 percent of sperm cells in the ejaculate fluid have a normal morphology or appropriately shaped structure.
The requirement of normal sperm morphology is higher for IVF. Reports show that about 20% of sperm should have a normal sperm morphology for a successful conception [2]. The requirement is high for IVF because this technique involves selecting the healthiest sperm for fertilization.
Conclusion
IVF technique is a hope for many couples facing problems with low sperm count and poor sperm motility. But many people don’t realize that this technique is no magic that can work for everyone.
There are some minimum requirements for IVF success. IVF success rate with low sperm count and motility is significantly low. If you are planning to utilize this technique for your next pregnancy, we recommend you book a consultation with a fertility specialist for an informed decision.
