Insights
Pubertal boys born after intracytoplasmic sperm injection (ICSI) have normal testosterone levels, similar to those conceived spontaneously. This suggests no immediate risk of gonadal dysfunction in ICSI-conceived males at age 14.
Area of Science:
- Reproductive Endocrinology
- Pediatric Andrology
- Infertility Treatment Outcomes
Background:
- Limited data exist on Leydig cell function in pubertal boys conceived via intracytoplasmic sperm injection (ICSI).
- Assessing gonadal function in children born to fathers with fertility issues is crucial.
- Testosterone levels serve as a key indicator of testicular function.
Purpose of the Study:
- To evaluate Leydig cell function in 14-year-old boys born after ICSI.
- To compare salivary testosterone levels between ICSI-conceived and spontaneously conceived (SC) boys.
- To investigate if paternal fertility status impacts testosterone levels in ICSI offspring.
Main Methods:
- Salivary testosterone levels were measured in the morning for 58 ICSI teenagers and 62 SC boys at age 14.
- The ICSI group was analyzed based on paternal oligozoospermia status.
- Statistical comparison of testosterone levels between the groups.
Main Results:
- No significant difference in salivary testosterone levels was observed between ICSI (113 ± 42 pg/ml) and SC (123 ± 56 pg/ml) teenagers.
- Testosterone levels in ICSI boys whose fathers had severe oligozoospermia were comparable to those whose fathers did not.
- Paternal fertility status did not appear to influence testosterone levels in ICSI offspring at age 14.
Conclusions:
- Pubertal boys conceived via ICSI demonstrate comparable testosterone levels to their spontaneously conceived peers.
- ICSI adolescents with fathers experiencing severe spermatogenesis issues show normal testosterone levels.
- Long-term monitoring of ICSI teenagers into adulthood is necessary to confirm sustained normal gonadal function.
Abstract:
BACKGROUND To date, no data exist about Leydig cell function of pubertal boys born after ICSI. To evaluate a potential risk of gonadal dysfunction in children born from fathers with compromised fertility, testicular function was assessed by the measurement of salivary testosterone. METHODS Morning salivary testosterone levels at the age of 14 years were compared between 58 ICSI teenagers who are part of the oldest ICSI cohort, and 62 boys born after spontaneous conception (SC). RESULTS Salivary testosterone levels were comparable between ICSI (113 ± 42 pg/ml) and SC (123 ± 56 pg/ml) teenagers at the age of 14 years. In the ICSI group, testosterone levels in boys from fathers with severe oligozoospermia were not different from concentrations in boys from fathers without severe oligozoospermia (115.5 ± 43 and 109 ± 41 pg/ml, respectively). CONCLUSIONS At the age of 14 years, pubertal ICSI boys show testosterone levels comparable to their peers born after SC. ICSI adolescents fathered from men with severely compromised spermatogenesis show testosterone levels comparable to those from fathers with normal spermatogenesis. This notwithstanding, further follow-up of ICSI teenagers into adulthood is mandatory to confirm a normal gonadal function.
