Summary
Total fertilization failure (TFF) in conventional in vitro fertilization (IVF) is linked to primary infertility and teratozoospermia. Intracytoplasmic sperm injection (ICSI) may help prevent TFF in affected patients.
Area of Science:
- Reproductive Medicine
- Infertility Research
- Assisted Reproductive Technologies
Context:
- Conventional in vitro fertilization (IVF) is a common treatment for infertility.
- Total fertilization failure (TFF) is a rare but significant complication of IVF.
- Understanding the causes of TFF is crucial for improving IVF success rates.
Purpose:
- To investigate the potential causes of total fertilization failure (TFF) in conventional IVF.
- To identify patient characteristics associated with TFF.
- To provide recommendations for preventing TFF.
Summary:
- A study of 552 couples undergoing conventional IVF found that 37 experienced TFF.
- Primary infertility and teratozoospermia were significantly more common in couples with TFF.
- No significant differences were observed in controlled ovarian hyperstimulation (COH) parameters, oocyte yield, or gonadotropin (Gn) dosage.
Impact:
- The findings suggest that specific patient factors, namely primary infertility and teratozoospermia, increase the risk of TFF.
- Intracytoplasmic sperm injection (ICSI) is proposed as a potential strategy to mitigate TFF in patients with teratozoospermia.
- This research can help clinicians personalize IVF protocols to reduce fertilization failures.

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...

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...
01:38Fertilization
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...
01:28Infertility in Females
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

01:17Understanding Species and Reproductive Barriers
A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...
