One-liner
This episode provides a high-yield review of infertility workup, emphasizing the pathophysiology of HPG axis dysfunction (e.g., PCOS vs. Turner Syndrome), and covering diverse causes including genetic syndromes (Primary Ciliary Dyskinesia) and structural/endocrine issues (Endometriosis, Varicocele).
High-yield summary
- HPG Axis Dysfunction: The diagnosis hinges on determining if the problem is primary ovarian failure (high FSH/LH), pituitary failure (low FSH/LH), or hypothalamic failure (low GnRH).
- PCOS vs. Turner Syndrome: PCOS typically presents with normal gonadotropin levels, while Turner syndrome (45, X) results in elevated FSH and LH due to streak ovaries.
- Primary Ciliary Dyskinesia (PCD): This autosomal recessive disorder affects cilia function across multiple systems: respiratory tract (chronic infections/bronchiectasis), reproductive tract (poor tubal motility), male germline (poor sperm motility), and cardiovascular system (loss of PIMP).
- Endometriosis: A common cause of infertility characterized by pain in the 3Ds (dysmenorrhea, dyspareunia, dyschezia) and structural damage to the uterus/ovaries.
- Male Factor Infertility: Key causes include varicocele (elevated temperature impairing spermatogenesis), anti-sperm antibodies (due to blood-test barrier breakdown following trauma/infection), and cystic fibrosis (thick cervical mucus).
Learning objectives
- Differentiate the hormonal profiles (FSH/LH) in primary vs. secondary ovarian failure.
- Identify the specific clinical manifestations and underlying mechanisms of common causes of infertility (e.g., PCOS, Endometriosis).
- Recognize the multisystemic nature of genetic disorders like Primary Ciliary Dyskinesia.
- Understand the pathophysiology behind male factor infertility, including varicocele formation and autoimmune responses.
- Correlate endocrine changes (e.g., hypothyroidism, lactation) with HPG axis suppression.
