İnfertilite Tanısında Biyokimyasal Parametrelere Genel Bakış
Özet
İnfertilite, 12 ay boyunca korunmasız ilişkiye rağmen çocuk sahibi olunamaması durumu olup, üreme çağındaki çiftlerin yaklaşık %10'unu etkileyen ortak bir problemdir. Tanı ve tedavi süreçlerinde biyokimyasal parametreler, hem kadın hem erkek için kritik bir yönlendirici rol oynar. Hormonal açıdan TSH ve serbest tiroksin (FT4) ölçümleri hipotiroidizm ile ilişkili ovulasyon bozukluklarının tespitinde önem taşırken, TRH stimülasyon testi subklinik hipotiroidizmin belirlenmesinde güvenilirdir. Erkeklerde anti-TPO antikorlarının artışı sperm hareketliliğinde azalmayla, yüksek serotonin seviyeleri ise düşük sperm sayısı ve motilitesiyle ilişkilendirilmiştir. AMH ölçümü üreme fonksiyonlarının değerlendirilmesinde kullanılırken, HCG ise erkek infertilite tedavisinde testosteron ve sperm üretimini tetiklemektedir. Kadınlarda östrojen baskınlığı endometriozise yol açabilirken, erkeklerde östrojen reseptör mutasyonları infertilite riskini artırır. Metabolik olarak Polikistik Over Sendromu (PKOS) olan hastalarda insülin direnci ve hiperinsülinemi, androjen üretimini artırarak anovulatuvar infertiliteye neden olur. Ayrıca D vitamini, sperm kalitesi ve gebelik sonuçları üzerinde olumlu etkilere sahiptir. Biyokimyasal sperm analizinde ise PSA, asit fosfataz, çinko, magnezyum ve fruktoz seviyeleri ile hiyalorunidaz gibi enzimlerin değerlendirilmesi, sperm konsantrasyonu, morfolojisi ve motilitesinin belirlenmesinde hayati öneme sahiptir.
Infertility is defined as the inability to conceive despite 12 months of unprotected intercourse, affecting approximately 10% of reproductive-aged couples worldwide. Biochemical parameters play a critical guiding role in diagnosis and treatment processes for both men and women. Hormonally, TSH and free thyroxine (FT4) measurements are crucial for detecting ovulation disorders associated with hypothyroidism, while the TRH stimulation test is reliable for identifying subclinical hypothyroidism. In men, increased anti-TPO antibodies are associated with decreased sperm motility, and elevated serotonin levels are linked to lower sperm counts and motility. AMH measurement evaluates reproductive functions, whereas HCG triggers testosterone and sperm production in male infertility treatment. Estrogen dominance in women can lead to endometriosis, while estrogen receptor mutations in men increase infertility risk. Metabolically, insulin resistance and hyperinsulinemia in patients with Polycystic Ovary Syndrome (PCOS) cause anovulatory infertility by increasing androgen production. Additionally, vitamin D has positive effects on sperm quality and pregnancy outcomes. In biochemical sperm analysis, evaluating PSA, acid phosphatase, zinc, magnesium, fructose levels, and enzymes like hyaluronidase is vital for determining sperm concentration, morphology, and motility.
