Objectives: To review the retrospective treatment results of the azoospermia patients during January 2001 to January 2002 in the fertility center.
Methods: One hundred males attempted intracytoplasmic sperm injection (ICSI) cycle for treatment of azoospermia. All patients were undergone sperm retrieval by percutaneous epididymal sperm aspiration (PESA) or testicular sperm extraction (TESE) while their wives received conventional ovarian hyperstimulation. The hormone levels, testicular histology, the rates of sperm retrieval, fertilization, implantation and pregnancy were analysed and evaluated.
Results: Sperm were retrieved by PESA in 76 of 100 (76%) and by TESE in 23 of 100 (23%) men of azoospermia. The fertilization rate, implantation rate and clinical pregnancy rate were 71.3%, 20.35% and 42.11% respectively in PESA group, and 75.18%, 22.05% and 41.60% respectively in TESA group. Thirty-two clinical pregnancies were achieved with 15 ongoing pregnancies and subsequent live delivery for 15 cases in PESA group, and 2 cases of miscarriage, while 10 clinical pregnancies were achieved with 6 ongoing pregnancies, 2 cases of live delivery and 2 cases of miscarriage in TESA group. One case failed to retrieve sperm by TESE and canceled.
Conclusions: Hormonal levels and testicular histology are unable to predict which men with azoospermia will have sperm retrieved by PESA and TESE. PESA and TESE with ICSI are effective methods to treat azoospermia. There were no significant differences in fertilization, implantation and clinical pregnancy rate between two groups.

Background: Non-obstructive azoospermia (NOA), the severe type of male infertility. The objective of this study was to evaluate the predictive accuracy of a prediction model of sperm retrieval failure with fine needle aspiration (FNA).
Methods: This study involved 769 NOA patients (dataset 1) undertaking FNA and 140 NOA patients undertaking mTESE (dataset 2).

This study focused on continuous monitoring of the immunocontraceptive effect of Improvac® vaccine on the sexual activity of male goats determined by measuring plasma testosterone levels, testicular biometric and ejaculate examination. The animals in the experimental group (n=12) were administered two doses of 2 ml of Improvac® at a four-week interval; the animals in the control group (n=5) received 2 ml of saline. Blood collection, semen collection and testicular measurements were performed at 14-day intervals.

Background: The presence of predominantly headless sperm in semen is a hallmark of acephalic spermatozoa syndrome, which is primarily caused by gene mutations in humans.
Purpose: To identify genetic causes for acephalic spermatozoa syndrome.
Methods: Polymerase chain reaction and Sanger sequencing were performed to define mutations in SUN5 and PMFBP1.

Objectives: This study investigates sperm utilization and disposal patterns in Oligoasthenoteratozoospermia (OAT) patients undergoing long-term sperm storage. OAT is a major contributor to male infertility. Cryopreservation is a common practice as a "fertility insurance" in case of further deterioration until azoospermia.

Except in cases of hypogonadotropic hypogonadism, the use of medical therapy before microsurgical testicular sperm extraction (micro-TESE) is controversial. In some studies, hormone therapy has been shown to improve the possibility of sperm retrieval during micro-TESE and even lead to the presence of sperm in the ejaculate in some cases, thereby obviating the need for micro-TESE. However, their routine use before micro-TESE in cases of nonobstructive azoospermia (NOA) being associated with hypergonadotropic hypogonadism and eugonadism (normogonadotropic condition) has not been supported with robust evidence.
