Summary
High sperm DNA fragmentation significantly reduces live-birth rates in IVF but not ICSI. This finding highlights the importance of assessing sperm DNA damage for improving assisted reproduction treatment outcomes.
Area of Science:
- Reproductive Science
- Andrology
- Genetics
Background:
- Sperm DNA damage negatively impacts pregnancy rates in assisted reproduction.
- Understanding the relationship between sperm DNA fragmentation and live-birth rates is crucial for optimizing treatment success.
Purpose of the Study:
- To investigate the correlation between sperm DNA fragmentation and live-birth rates following in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI).
Main Methods:
- The alkaline Comet assay was used to measure sperm DNA fragmentation in semen samples.
- Semen samples were analyzed before and after density-gradient centrifugation.
- Data were collected from 203 couples undergoing IVF and 136 couples undergoing ICSI.
Main Results:
- For IVF, couples with <25% sperm DNA fragmentation had a 33% live-birth rate, versus 13% for those with >50% fragmentation.
- No significant differences in sperm DNA damage were observed across patient groups undergoing ICSI.
- High sperm DNA damage was prevalent in idiopathic infertility cases, associated with lower IVF live-birth rates.
Conclusions:
- Sperm DNA damage assessed by the Comet assay shows a strong inverse relationship with live-birth rates after IVF.
- Sperm DNA fragmentation significantly affects assisted reproduction treatment outcomes, particularly pregnancy rates in IVF.
- Further research may explore targeted interventions for sperm DNA damage to improve IVF success rates.

01:41Spermatogenesis
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
01:23Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
01:24In Vitro Fertilization
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:38Fertilization
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
01:57Meiosis II
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each containing...
