Abnormal sperm and birth defects

Abnormal sperm and birth defects
Mar 15, 2025
Abnormal sperm morphology occurs when sperm possess certain defects in shape or size that could affect its ability to reach and penetrate an egg...
The morphological and/or functional defects of the sperm flagellum induce reduced sperm motility. The semen analysis in the men of infertile couples frequently shows reduced sperm motility, both as an isolated finding and in association with other semen alterations, such as a low number of sperm or a high percentage of malformed sperm.
Abnormal sperm morphology can potentially contribute to birth defects, although it is not a direct cause. When a sperm with abnormal morphology fertilizes an egg, it may lead to genetic abnormalities in the resulting embryo.
Sperm genetic testing has been proposed for clinical diagnosis of possible causes of male infertility. We reviewed the most remarkable publications of sperm DNA integrity and sperm aneuploidy as they relate to clinical outcomes, and the relationship between both genetic defects, and its association to embryo aneuploidy and recurrent pregnancy loss.
Yes, poor sperm quality can increase the risk of birth defects by contributing to genetic abnormalities and developmental issues.

Birth defects are mostly due to damage in the DNA package and it can be from either partner. Abnormal sperm morphology will make it difficult to conceive but may not cause any defects in the baby. FAQs How to Correct Sperm Morphology? Simple changes to lifestyle and diet can have a big impact on your sperm health and morphology.
In females, it interferes with follicle development and egg maturation. Lower quality gametes (sperm/egg) → Higher risk of abnormal cell division after fertilization → Increased chance of birth defects. 🔬 3. Disrupted Early Heart Formation The first 6-7 weeks of pregnancy are crucial for heart development.
Low sperm morphology is not directly linked to causing birth defects. However, abnormal sperm can lead to fertilization of the egg with genetic material that may be compromised, potentially resulting in miscarriages or congenital abnormalities.
Aneuploidy can cause early miscarriages and failed IVF cycles due to implantation failure and chromosomal birth defects. What is 9p21 test for? This test identifies individuals who may be at an increased risk of premature CVD which allows for risk reclassification and more aggressive management of modifiable risk factors.
Sperm morphology refers to the size and shape of sperm. It's one factor that healthcare professionals look at as part of a semen test. The test helps show if you're able to have children, called fertility. In the lab, technicians look at sperm under a microscope to see if the sperm meet strict ...
Sperm morphology refers to the size and shape of individual sperm. Read to know if Abnormal Sperm Morphology may cause birth defects.
Abn sperm/defects: Abnormal sperm shape suggests "defective" sperm/abnormal sperm content which could result in infertility or possibly "defective" conception: you would never see an infertility center inserting an abnormally shaped sperm into an ovum (icsi/suzi). High "abnormal" counts would generally lead to an "assisted" fertilization.
Sperm morphology defects can be detected during diagnostic fertility testing and may indicate possible fertility issues.
Sperm disorders include defects in quality or quantity of sperm produced and defects in sperm emission. Diagnosis is by semen analysis and genetic testing. The most effective treatment is usually in vitro fertilization via intracytoplasmic sperm injection.
Learn about Sperm Abnormalities Causes and factors that may affect sperm quality, as well as treatments and tips to improve reproductive health and increase fertility.
Not applicable. Study design, size, duration: To determine if the severity of male factor infertilty, as assessed via sperm quality and mode of conception, is associated with BD rates, we performed a retrospective cohort study. Fathers with semen analysis data in the Baylor College of Medicine Semen Database (BCMSD) were linked with their offspring using Texas Birth Defects Registry (TBDFR ...
Other genetic disorders can also impair fertility, such as malformed sperm. There is no significant relationship between semen parameters and defect rates in live or still births, even when considering mode of conception. If abnormal sperm fertilizes an egg, it could lead to complications like miscarriage or birth defects.
Teratozoospermia is the medical term used to refer to abnormal sperm morphology, caused by either defects in the head, midpiece, and/or tail. According to the criteria published in 2010 by the World Health Organization (WHO), a man has teratozoospermia when more than 96% of the sperms he produces are abnormally shaped.

Other causes of birth defects can include exposures of many types of substances (teratogens) to the developing baby. Gendered terms are used here to talk about anatomy and health risk.
The present paper reviews in detail ultrastructural and molecular studies addressed to characterize different phenotypes of sperm pathology in sterile men. In each case ultrastructural, immunocytochemical, molecular and genetic information is provided to differentiate two main kinds of sperm pathologies: systematic phenotypes with known or suspected genetic origin and non-systematic ones ...
, Answer Section, , Sperm morphology refers to the size and shape of sperm. It's one factor that healthcare professionals look at as part of a semen test. The test helps show if you're able to have children, called fertility. In the lab, technicians look at sperm under a microscope to see if the sperm meet strict standards. The lab reports the percentage of sperm that meet those standards ...

According to a study published by the National Institutes of Health, genetic disorders cause 2%-8% of male infertility cases. Genetic testing may be recommended if the man has a very low sperm count, no sperm in semen or physical defects such as small testicles, and if he and his partner have experienced multiple miscarriages.
Find information on birth defects, including what causes them, how they're diagnosed, and how they can be prevented.
Also, we focus here on the non-syndromic infertility, i.e. infertilities which are not associated with other pathologies. Abnormalities of the sperm head Abnormalities of the sperm head provide the three most severe and characteristic sperm defects caused in most cases by single gene defects.
Birth Defects Birth defects are differences in the way your child's body develops. There are several types of birth defects, with causes that range from genetic changes to environmental factors. Examples include congenital heart conditions, a cleft lip and Down syndrome.
Genital birth defects may be caused by abnormal levels of sex hormones during fetal development, chromosome abnormalities, environmental factors, or inherited factors. The diagnosis depends on the defect and may include imaging tests. Many genital defects require surgery. (See also Overview of Kidney and Urinary Tract Birth Defects.)
Apert syndrome is a serious disfiguring birth defect. The report suggests that socioeconomic, ethnic and/or dietary factors may also influence how age affects human sperm quality.
Genital birth defects may be caused by abnormal levels of sex hormones during fetal development, chromosome abnormalities, environmental factors, or inherited factors.
Evaluating infertile men with isolated sperm defects may allow us to determine which specific sperm abnormality is most closely linked to sperm DNA damage and help further our understanding of the etiology of sperm DNA damage in infertile men.
Approximately 10%-15% of couples are infertile, and a male factor is involved in almost half of these cases. This observation is due in part to defects in spermatogenesis, and the underlying causes, including genetic abnormalities, remain largely ...
Abnormal sperm morphology impacted neither the pregnancy rate nor the live birth rate in couples undergoing intrauterine insemination. These results can be used to reassure couples who undergo intrauterine insemination that there is a minimal impact of abnormal sperm morphology on the live birth rat …
They can be defined as structural or functional anomalies (for example, metabolic disorders) that occur during intrauterine life and can be identified prenatally, at birth, or sometimes may only be detected later in infancy, such as hearing defects. Broadly, congenital refers to the existence at or before birth.
Objective: This systematic review and meta-analysis was aimed at determining whether paternal age is a risk factor for offspring birth defects. Results: A total of 38 and 11 studies were included in the systematic review and meta-analysis, ...
As well, sperm with high levels of DNA damage or abnormal DNA packaging has negative effects on embryo development and pregnancy outcomes, including pregnancy loss, recurrent spontaneous abortion, and lower live birth rates [5, 6, 7, 8, 9, 10, 11].
A birth defect[a] is an abnormal condition that is present at birth, regardless of its cause. [2] Birth defects may result in disabilities that may be physical, intellectual, or developmental. [2]
