Sperm looks good and is more likely to conceive. Long term smoking increases deformity rate
Good looking sperm can easily make women conceive
Mr. Liu, almost 40 years old, his wife has never been pregnant with a child. At this age, he also began to worry. After going to the hospital for a check-up, he found that his sperm motility was poor. What made him even more disheartened was that 98% of his sperm were deformed - some had head deformities, some had neck deformities, and some even had no tail. Faced with such a sperm condition, the couple became anxious and said, "With poor vitality and deformities, can we still have normal children?" The wife cried bitterly, feeling that she couldn't have a child in her lifetime.
No wonder I didn't let my wife have a child, is it because of the high sperm abnormality rate? "Mr. Liu asked anxiously when he met the doctor. Long Xiaolin, the chief physician of the Reproductive Center of the Third Affiliated Hospital of Guangzhou Medical University, explained that it is indeed true that normal men ejaculate tens of millions of sperm during each sexual activity. However, with so many sperm, only a very small number of elite sperm can truly reach the ampulla of the female fallopian tube and obtain contact with the egg. Due to various mechanisms in the egg and female reproductive tract that select and eliminate sperm, usually only one sperm binds to the egg to complete fertilization.
Currently, research cannot accurately predict which sperm can be fertilized. However, studying the characteristics of a group of sperm that are close to fertilization reveals some patterns in their "appearance" that can be followed. Research has found that sperm that can penetrate female cervical mucus are considered to have fertilization potential. Analysis of the morphological characteristics of this part of sperm reveals that their head has a smooth shape, regular curvature, generally elliptical shape, a aspect ratio of 1.5, and the acrosome area accounts for 40% -70% of the head area. The tail may have a curved shape, but not an angular bend. Sperm with this appearance is called "normal form" and the conception rate is much higher.
Normal sperm morphology is sufficient as long as it is ≥ 4% or more
In the third edition of the WHO manual, it is stipulated that males with normal reproductive ability should have normal sperm morphology accounting for over 30%; The 4th edition of the WHO manual stipulates that normal form only accounts for more than 15%; In the 5th edition of the 2010 WHO manual, it was stipulated that normal form only requires ≥ 4% or more. From this, it can be seen that the morphology of sperm is not as we imagine, they are 100% normal, and on the contrary, most of them are themselves deformed.
Long Xiaolin pointed out that even for men with normal fertility, the normal morphology rate of sperm is often only between 4% -25%, which means that 75% -96% of sperm will be judged as abnormal, and this part of sperm will be eliminated by the female reproductive tract without developing fertility. Upon hearing this result, Mr. Liu's mood slightly calmed down, as he turned out to be only 2% below the standard. However, he still had a question in his mind, 'Is there a high proportion of abnormal sperm in him? Will his wife also have abnormal babies after she becomes pregnant?'
Long Xiaolin said that the so-called "deformity" is an indicator we use to evaluate sperm fertility, and an increase in sperm deformity rate will increase the difficulty of natural conception (which can also affect the success rate of artificial insemination and "in vitro fertilization"). Simply put, the morphology of sperm is mainly related to the probability of pregnancy, but not to the essence of sperm (genetic material). Just as there is no direct relationship between a person's appearance and their essence, whether a person is good-looking or not cannot indicate their health. It cannot be said that a person who is not good-looking is not healthy. Similarly, it cannot be said that if the sperm morphology is poor, there will be problems with the genetic material of the sperm, which can lead to abnormal birth or stillbirth miscarriage. There is also no necessary connection between sperm abnormalities and whether or not to have abnormal offspring.
So, for the problem of male sperm abnormalities, we cannot magnify the small problem, otherwise the erroneous logic will continue to develop, and even a large amount of medication will not have much effect.
