Background: The paternal role in embryogenesis is much more than providing a haploid genome. The spermatozoa have crucial roles related to embryogenesis' epigenetic regulation, fusion of gametes, and cleavage, which may influence intracytoplasmic sperm injection outcomes.
Objectives: To study whether paternal age, length of ejaculatory abstinence and semen parameters influence the outcomes of intracytoplasmic sperm injection in the oocyte recipients from egg-sharing donation cycles.
In order to increase the success rate of in vitro fertilization cycles, several studies have focused on the identification of the embryo with higher implantation potential. Despite recent advances in the reproductive medicine, based on the OMICs technology, routinely applicable methodologies are still needed. Thus, in most fertilization centers embryo selection for transfer is still based on morphological parameters evaluated under light microscopy.

Methods: assessed were 11 intracytoplasmatic sperm injection (ICSI) cycles from couples whose men were HIV seropositive (HIV Group), and 35 cycles in which semen donors' samples were used in ICSI procedures (Control Group). Semen samples from Control Group were submitted to routine semen analysis, sperm wash and cryopreservation.
Article Synopsis
- The term "biological clock" typically refers to the age-related decline in fertility and hormone levels in women, but emerging research indicates that men also experience similar consequences as they age.
- Studies show that the chances of a couple taking over a year to conceive almost doubles as male age increases, highlighting the significance of paternal age in fertility assessments.
- Additionally, older men face greater risks of fertility decline and related health issues, making it crucial for patients and healthcare providers to recognize the impact of the male biological clock on reproductive and overall health.
Purpose: To evaluate the relationship between the postvasectomy period and sperm reproductive capacity after ICSI.
Methods: Seventy-seven ICSI cycles with percutaneous epididymal sperm aspiration (PESA) were reviewed. Patients were divided into 4 groups according to the interval after vasectomy: 0 - 5 years (G1); 6 - 8 years (G2); 9 - 14 years (G3), and > 15 years (G4).
