Male fertility depends on a continuous hormonal system and healthy sperm production. Understanding the male hormonal axis and conditions like azoospermia is essential for diagnosing and treating male infertility.
What is the Male Hormonal Axis (HPG Axis)?
How the Hormonal System Works
The hypothalamic-pituitary-gonadal (HPG) axis controls sperm production and testosterone levels.
Key Hormones Involved
- GnRH (Hypothalamus)
- LH & FSH (Pituitary gland)
- Testosterone (Testes)
Role of Testosterone, FSH & LH
LH and Testosterone Production
LH stimulates Leydig cells to produce testosterone, essential for male fertility and libido.
FSH and Sperm Production
FSH supports Sertoli cells, which help in sperm development.
Spermatogenesis Process
Continuous Sperm Production
Sperm production is ongoing and takes around 70–90 days.
Factors Affecting Sperm Health
Stress, illness, lifestyle, and medications can impact sperm production.
Hormonal Imbalance in Men
Common Causes
- Low testosterone
- High prolactin
- Pituitary disorders
Lifestyle Impact
Obesity, smoking, and stress can reduce fertility.
Diagnosis of Male Hormonal Issues
Hormone Testing
- Testosterone
- FSH & LH
- Prolactin
Best Time for Testing
Morning testing is recommended for accurate testosterone levels.
What is Azoospermia?
Definition
Azoospermia is the absence of sperm in semen.
How Common is It?
It affects about 1% of men and 10–15% of infertile males.
Types of Azoospermia
Obstructive Azoospermia (OA)
Sperm production is normal, but a blockage prevents sperm release.
Non-Obstructive Azoospermia (NOA)
There is a problem with sperm production in the testes.
Causes of Azoospermia
Obstructive Causes
- Vasectomy
- Infections
- Congenital absence of vas deferens
Non-Obstructive Causes
- Genetic disorders
- Hormonal imbalance
- Testicular failure
Diagnosis of Azoospermia
Key Tests
- Semen analysis
- Hormone tests
- Ultrasound
Advanced Testing
Genetic testing and imaging may be required.
Treatment Options
For Obstructive Azoospermia
- Surgical correction
- Sperm retrieval (PESA, TESA)
- IVF with ICSI
For Non-Obstructive Azoospermia
- Hormonal therapy
- Micro-TESE surgery
- IVF options
