What We Do and Why We Do It What We Do and Why We Do ItJumana Adham husseiniLab Director/Senior Embryologist
Semen Analysis • Liquefaction • Volume • Count /ml / (Total) • Motility • Progression • Morphology • Agglutination • WHO (Criteria) 5th edition 2010-2013 • Lower reference limit • Conc. 15m/ml (total 39m/ml) • Volume (1.5mls) • Total motility 40% • 32% progressive motility • Normal forms 4%, (yet 15% normal forms defines teratozoospermia.)
Important Point to Remember • Severe reduction in fertilization might arise when < 4%strictly normal forms are present.
Other Parameters Color Odor • Opaque and grayish white • Changes to yellowish white as days of abstinence ↑. • Blood gives it a reddish brownish color. • ↓ conc. And WBCs ► transparent and watery consistency. • The odor of the flower of the chestnut plant. • Odor is caused by oxidation of the spermin secreted by the prostate. • Absence of odor ► Abnormal prostate function due to infection
The pH • SHOULD BE WITHIN RANGE ( 7.2-8) • Human semen should liquefy at pH 6.9-8.8 within 20- 30 minutes. • > 8 → Acute prostatitis, vesiculitis or bilateral epididymites. • <7 → Obstruction of ejaculatory ducts, only prostatic fluid secreted. • <7.2-► <6 → chronic infection.
Liquefaction • Vesiculase • Seminine • (Alpha) α-chymotrypsin • Lysozyme • Hyaluronidase • α- Amylase • Prostatic spec. antig. / prost. Acid phos. • None Liquefaction ≥ 1 hr. ► Prostatic infection or other pathological state!?
1-FRUCTOSE • A sperm metabolite • Done to check that ducts are normal. • Fructose levels are androgen dependant • ↓Low levels →androgen deficiency
2- L-CARNITINE Epididimal function is marked by L- carnitine. (↑ levels →none -Obstructive azoospermia. ↓ levels→ obstructive azoospermia. (post epididymal)
3- (PAP) Prostatic Acid Phosphatase • Prostatic Activity is Measured by seminal Acid Phosphatase (PAP) • ↑ Acid phosphatase → obstructed ejaculatory ducts. (↓ semen volume, ↓ fructose.) • PAP test determines the health of the prostate.
Other tests 4-Transferrin 5- Zinc and Selinuim Sertoli cells are the source of 80%. Very ↓ indicate Azoospermia. ↓ Low in oligospermia. ↑Highestin normal men. • Essential for germinal cell differ., and normal spermatogenesis, and sperm function. • Selenium deficiency leads to anomalies of neck and midpiece. • Zn ►chromatin decondensation.
Important Definitions • Normozoospermia • Oligoz0ospermia • Asthenozoospermia • Teratozoospermia • Oligo-astheno-terato-zoospermia • Necrozoospermia • Azoospermia • Aspermia • Cryptozoospermia
RECOMENDATIONS Repeat /Semen Analysis IUI/ IVF/ ICSI SURVIVAL EVALUTION VITALITY STAIN (EOSIN) SSU (♀♂) Selective swim up DNA FRAGMENTATION. SPERM ANEUPLOIDY
Mature & Immature eggs IVF image of a mature egg on the day of egg retrievalWe call this the metaphase II, or "M2" stage The presence of the polar body (red arrow) shows that the egg is mature • Photo of a very immature egg • Corona and cumulus cells are tightly packed around the egg
IMPORTANT DEFENITIONS IVF ICSI COMBINED IVF/ICSI (split) CRYOPRESERVATION (VITRIFICATION) PESA/TESA/TESE PGS PGD

THE DIFFERENCE BETWEEN IVF AND ICSI • IN IVF NATURAL SELECTION THE ZONA PELLUCIDA IS ABLE TO IDENTIFY GENETICALLY ALTERED SPERMATOZOA • GENETICALLY ALTERED SPERMATOZOA WITH POOR MOTILITY AND DNA DAMAGE HAVE LOW FITNESS IN OOCYTE FERTILIZATION • IN ICSI THE NATURAL PROCESS OF SPERM /OOCYTE INTERACTION IS BYPASSED.
