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.

Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Testes: Histology01:27

Testes: Histology

A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
The spermatogenic cells, responsible for producing sperm, are...
Infertility in Males01:23

Infertility 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...

Testes: Gross Anatomy

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...
Spermatogenesis01:41

Spermatogenesis

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...
