Idiopathic semen quality abnormalities include idiopathic oligozoospermia, asthenospermia, teratospermia, azoospermia and idiopathic abnormal semen liquefaction. The possible causes of idiopathic semen quality abnormality include age, non-inflammatory function changes of subsidiary gonadal organs, infection, genetic abnormalities, sperm mitochondrial changes, effects of environmental pollutants, and subtle hormonal changes. The diagnosis of idiopathic oligozoospermia, asthenospermia, teratospermia and azoospermia require detailed inquiry of the case history, physical examination, semen analysis, determination of reproductive hormones, genetic and immunological examinations, and so on, to exclude possible known causes. The treatment of idiopathic oligozoospermia, asthenospermia, and teratospermia may involve the use of Western medicines, such as clomiphene citrate, tamoxifen, recombinant FSH, Andriol, compound zinc and selenium, L-carnitine, recombinant growth hormone and pentoxifylline, the application of traditional Chinese drugs, or the combination of traditional Chinese and Western medicine. Idiopathic azoospermia can be treated by assisted reproductive technology based on the medication of spermatogenesis-promoting drugs, and idiopathic abnormal semen liquefaction can be managed with traditional Chinese drugs, integrated traditional Chinese and Western medicine, or in vitro semen processing technology. With the development of diagnostic technology, it is expected that more specific therapeutic methods will be established for idiopathic semen quality abnormalities and their incidence will be reduced.

OBJECTIVETo evaluate the accuracy and precision of 4 methods including Hemacytometer, Makler chamber, Cell-VU chamber, and computer-aided semen analysis for determining sperm concentration.

METHODSLatex bead solutions with concentrations known as (35 +/- 5) x 10(6)/ml and (18.0 +/- 2.5) x 10(6)/ml and semen samples (n = 54) were counted by the above 4 methods and the results were then compared.

RESULTSMean bead concentrations for Hemacytometer, Makler, Cell-VU chambers and CASA were (44.84 +/- 4.86), (52.36 +/- 7.78), (39.70 +/- 4.76), (28.53 +/- 2.06) x 10(6)/ml respectively for the standard solution containing (35 +/- 5) x 10(6)/ml, and (21.04 +/- 1.87), (24.54 +/- 3.67), (19.09 +/- 2.02), (14.62 +/- 0.95) x 10(6)/ml respectively for a standard solution containing (18 +/- 2.5) x 10(6)/ml. The results of Cell-VU chamber were consistently similar and close to the standard solutions, while those of Hemacytometer, Makler chambers were overestimated, and those of CASA were underestimated. The coefficients of variation for Hemacytometer, Makler, Cell-VU chambers and CASA were 10.81%, 14.86%, 12.80%, and 7.22% respectively for a higher standard solution, while 8.89%, 14.96%, 10.58%, and 6.50% respectively for a lower standard solution. CASA has the lowest CV%. When semen samples were counted, the results of Hemacytometer, Makler, Cell-VU chambers and CASA were (76.98 +/- 59.90), (63.89 +/- 53.84), (45.28 +/- 34.52), (41.96 +/- 31.93) x 10(6)/ml respectively. There wasn't any significant difference either between Cell-VU chamber and CASA (P = 0.71), or between Hemacytometer and Makler chamber (P = 0.14), while there was significant difference between Cell-VU chamber or CASA and Hemacytometer or Makler chamber (P < 0.05 or P <0.01).

CONCLUSIONWhen counting semen sample, there wasnt any significant difference between Cell-VU chamber and CASA. Each laboratory can select its own proper method for manual or computer-aided analysis.

OBJECTIVETo explore genetic etiologies of a patient with severe oligozoospermia and asthenozoospermia.

METHODSG-banded karyotyping and fluorescence in situ hybridization (FISH) were used to characterize the origin and structure of the abnormal chromosome discovered in this patient. Multiplex polymerase chain reaction (PCR) was used to detect microdeletion of azoospermia factor (AZF).

RESULTSG-banding revealed a karyotype of 45,X,der(15) (?::p11.2→ qter)dn for the patient. Dual-color FISH confirmed that SRY gene was present in a segment attached to the short arm of chromosome 15. Sex chromosome mosaicism and numerical abnormality therefore were both present. Dual-color FISH revealed karyotype of nuc ish(DXZ1× 1, SRY× 1)[390/400]/(DXZ1× 2, SRY× 1) [10/400]. Four-color FISH showed that the abnormal chromosome 15 has derived from a pseudodicentric (Y;15) translocation, and that the breakpoint on Y chromosome was located at Yq12. G-banding and FISH results confirmed that the karyotype was 45,X,der(15)(?::p11.2→ qter)dn.ish psu dic(15;Y)(p11.2;q12)(D15Z1+ , SNRPN+ , PML+ ; SRY+ , DYZ3+ , DYZ1+ ). Microdeletion of AZFc combined with sY254 deletion was detected by multiplex PCR.

CONCLUSIONCytogenetic and molecular genetic analysis of the patient has indicated meiotic disturbances with spermatogenetic arrest resulting from a pseudodicentric chromosome derived from Y;15 translocation and spermatogenesis dysfunction resulting from partial deletion of AZFc region.

OBJECTIVETo assess the diagnostic value of alpha-glycosidase for epididymal lump induced obstructive azoospermia.

METHODSSeventy-six infertile men with normal spermatogenic function were divided according to sperm density into a normal density group (n = 27), an oligospermia group (n = 21) and an obstructive azoospermia group (n = 28), and another 30 fertile males were included as normal controls. Semen plasma alpha-glycosidase, leucocyte count, sexual hormone levels and the diameters of the epididymal lumps were measured and their correlations were analyzed.

RESULTSalpha-Glycosidase in the obstructive azoospermia group was significantly lower than that of the other groups (P <0.05), and negatively correlated with epididymal volume (r = -0.417, P <0.05) and leucocyte count (r = -0.342, P <0.05).

CONCLUSIONAlpha-Glycosidase has been proved of diagnostic value for epididymal obstructive azoospermia.

Testicular biopsy is mandatory in azoospermic men with normal sized testes to distinguish between ductal obstruction and spermatogenic failure as the cause of azoospermia. In men with poor semen quality or azoospermia and small testes, the results of a pathologic evaluation will rarely if ever alter therapy. However, the biopsy often assists in making a definitive diagnosis which helps the physician in giving the patient a prognosis and avoiding unnecessary treatment in irredeemable situation. We performed 25 cases of testicular biopsy in infertile men, procuring the results as below: 1. Testicular biopsy specimen were classified into 5 group histopathologically: germ cell aplasia, 6 cases (24%); spermatogenic arrest, 8 cases (32%); hypospermatogenesis, 5 cases (20%); peritubular or tubular fibrosis, 3 cases (12%); normal or obstructive, 3 cases (12%). 2. In 25 cases, 18 cases were azoospermia and 7 cases were oligospermia. 3. In 13 cases (52%), the lesions were localized both in the seminiferous tubule and in the interstitial tissue and in 9 cases (36%), the lesions were localized only in the seminiferous tubule, and 3 cases (12%)were normal.

Testicular biopsy is an important tool in the diagnosis and management of male infertility. The increasing use of this procedure has permitted a rational classification of the testicular lesion responsible for infertility and provide an intelligent basis for the institution of corrective measures or the withholding of therapy in cases in which the biopsy indicates a hopeless prognosis for fertility. The testicular biopsy findings of 48 azoospermia cases were evaluated in aspects of testicular size and past history. The following results were obtained. 1. The biopsy findings of 8 cases with normal sized testes and no nodules of both epididymimides and vasa deferens were normal in 4 cases, germinal aplasia in 2 cases, maturation arrest in 1 case and hypospermatogenesis in 1 case. 2. The biopsy findings of 23 cases with small sized testes and no nodules of both epididymides and vasa deferens were germinal aplasia in 13 cases, generalized fibrosis in 6 cases, maturation arrest in 3 cases and hypospermatogenesis in 1 case. 3. The past history of 17 cases with normal sized testes and bilateral induration of epididymides of vasa deferens revealed nonspecific epididymitis in 6 cases, tuberculous epididymides in 6 cases, tuberculous epididymitis in 5 cases, vasectomy in 5 cases and trauma of scrotum in 1 case. The biopsy findings of these cases were normal in 10 cases, hypospermatogenesis in 3 cases, testicular blockage in 3 cases and atrophy in 1 case.

OBJECTIVETo compare the clinical efficacy of 3 different treatment programs for oligospermia patients of Shen-essence deficiency syndrome (SEDS).

METHODSTotally 450 male patients were randomly assigned to 3 groups, i.e., the treatment group, the control group 1, and the control group 2, 150 in each group. Patients in the treatment group were treated by Bushen Yijing Decoction (BYD), tamoxifen tablet (TT), Licorzine Capsule (LC), and Vitamin E Soft Capsule (VESC). Those in the control group 1 were treated by BYD, LC, and VESC. Those in the control group 2 were treated by TT, LC, and VESC. All patients were treated for 3 months. Their pregnant rates were compared. Clinical efficacies of each Chinese medical symptom and sperm parameters [sperm density, grade a sperm motility rate, grade (a + b) sperm motility rate, grade (a + b + c) sperm motility rate, and normal sperm morphology rate] were compared before and after treatment.

RESULTSAt 3 months after treatment 61 patients were pregnant in the treatment group, 36 patients were pregnant in the control group 1, and 30 patients were pregnant in the control group 2. The differences in the sperm density, grade a sperm motility rate, and grade (a + b) sperm motility rate, and grade (a + b + c) sperm motility rate between before and after treatment were significantly higher in the treatment group than in the control group 1 and the control group 2 (P < 0.01). The difference in the normal sperm morphology rate between before and after treatment was obviously higher in the treatment group and the control group 1 than in the control group 2 (P < 0.01). Better results were obtained in the treatment group and the control group 1 in improving the sexual apathy, soreness and weakness of waist and knees, impotence, premature ejaculation, seminal emission, dizziness, tinnitus, forgetfulness, alopecia, when compared with the control group 2 (P < 0.01, P < 0.05). There was no statistical difference in the total effective rate of improving Chinese medical symptoms between the treatment group and the control group 1 (P > 0.05).

CONCLUSIONBYD combined with TT, LC, and VESC could significantly improve sperm qualities and clinical Chinese medical symptoms of oligospermia patients of SEDS.

Oligo-astheno-teratozoospermia (OAT) which perplexes doctors and patients due to its complicated etiology, atypical symptoms and poor clinical efficacy, is a general term for the three pathological states of abnormal semen. OAT is the main factor of male infertility. It is also a hot and difficult point in present studies. Empiric drug is the most popular treatment of this disease in the modern medicine. Chinese medicine (CM) is one of the main methods for the treatment of this disease, and it has certain clinical effect. The author believes that the use of modern medical technology to make the diagnosis as clear as possible is the key to treat OAT. The combination of syndrome and disease differentiation is the main mode in the treatment of OAT. Microscopic syndrome differentiation and macroscopic evidence embodies the basic principle of "Si Wai Chuai Nei" and broadens the perspective of CM syndrome differentiation. Classification and treatment are basic methods for the treatment of OAT. The treatment should not be limited to the Shen (Kidney), instead it should focus on the whole body condition. At different stages, the treatment should also pay attention to strengthening the Pi (Spleen), nourishing the Gan (Liver) and promoting blood circulation. Complementing Chinese and Western medicine, and highlighting the characteristics and advantages of CM treatment, have a great guiding value for the treatment of OAT.

OBJECTIVETo evaluate the effect of short-course kidney-invigorating therapy on near-term semen quality in asthenozoospermic men with kidney deficiency.

METHODSBased on the differential types in traditional Chinese medicine, 121 asthenozoospermia patients received at our clinic of andrology were divided into groups A (kidney-yin deficiency), B (kidney-yang deficiency) and C (spleen and kidney deficiency), and treated with Yougui Decoction plus Wuziyanzong Pills, Jinkuishenqi Pills plus Wuziyanzong Pills, and Shizi Decoction plus Liujunzi Decoction, respectively, all given once daily for 4 weeks. Sperm parameters of the patients were analyzed with the computer-assisted sperm analysis system before and after treatment and compared among the three groups.

RESULTSThe baseline sperm concentrations in groups A, B and C ([70.4 +/- 38.6], [73.5 +/- 40.2] and [56.0 +/-34.4] x 10(6)/ml) showed no significant differences from those after medication ([74.4 +/- 32.6], [67.0 +/- 30.8] and [58.6 +/- 24.6] x 10(6)/ml) (P > 0.05). The percentages of grade a sperm in the three groups were (12.9 +/- 5.3)%, (13.7 +/- 7.7)% and (12.9 +/- 6.4)% respectively after treatment, significantly higher than (9.9 +/- 6.7)%, (9.3 +/- 5.4)% and (9.0 +/- 6.8)% before treatment (P < 0.05), and so were the percentages of grade a + b sperm ([37.4 +/- 10.2 ]%, [35.7 +/- 13.7]% and [35.9 +/- 12.3]% after treatment versus [29.6 +/- 13.2]%, [27.5 +/- 10.4]% and [28.3 +/- 12.1]% before treatment, P < 0.05). All the three groups showed significantly increased sperm motility after treatment ([53.8 +/- 10.5]%, [52.6 +/- 15.2]% and [51.1 +/- 13.1]%) as compared with the baseline levels ([44.3 +/- 14.0]%, [43.5 +/- 15.0]% and [42.4 +/- 14.9]%) (P < 0.05). The cure rate and total effectiveness rate were significantly higher in group B than in A (P < 0.05), but had no significant differences between either A and C or B and C (P > 0.05).

CONCLUSIONShort-course kidney-invigorating therapy can significantly improve near-term semen quality in asthenozoospermic men with kidney asthenia, especially in those with kidney-yang deficiency, and it has no obvious adverse effects.

OBJECTIVEThis study is in an attempt to evaluate the diagnostic significance to predict the spermatogenesis of azoospermic men in examination of serum follicle-stimulating hormone (FSH) combination with serum inhibin B (INHB).

METHODSQuantitative examination of serum FSH and INHB was performed in 95 case of azoospermic men. According to their classifications of testicular biopsy with histopathological examination, there were 20 patients of Sertoli cell only, 25 of hypospermatogenesis, 18 of spermatogenic maturation arrest (complete or incomplete), and 32 of normal spermatogenesis. The association of serum FSH and INHB levels with histopathological classifications were analyzed by using statistical software.

RESULTSSerum FSH, INHB and INHB/FSH levels of Sertoli cell only differed with statistical significance from hypospermatogenesis, spermatogenic maturation arrest and normal spermatogenesis (P<0.05). FSH, in which there were no statistical significance among the latter three classifications (P>0.05). Serum FSH, INHB and INHB/FSH levels were no relationship with maturation arrest (P>0.05), but were negatively related to the other classifications (P<0.05). INHB level less than 28.55 pg/ml predicted Sertoli cell only in a sensitivity of 97% and a specificity of 85%.

CONCLUSIONSerum FSH and INHB levels is ineffective to distinguish the spermatogenic classifications from azoospermic men, but they are available to confirm the disease of Sertoli cell only. The other abnormalities of azoospermic men is also dependent on bioptic histopathology to confirm the subtypes.
