1/387. Spontaneous pregnancy following therapeutic approach of an infertile man with aspermia/obstructive azoospermia.

    The combination of aspermia and obstructive azoospermia in the same infertile man is a rather rare entity. In the case reported here, all diagnostic criteria as well as subsequent recovery following two operations are compatible with an inflammatory origin. In such cases assisted reproduction should be recommended. However, in this case, an early spontaneous pregnancy rendered this unnecessary.

2/387. male infertility: possible association with valproate exposure.

    PURPOSE: To describe a potential association between male infertility and valproate (VPA) exposure. VPA has been implicated in the development of polycystic ovarian disease and subsequent menstrual and infertility problems in women with epilepsy. infertility has been well described in population-based studies of persons with epilepsy. The low marital rates for men with epilepsy have previously been thought to play a major contributing role. methods: We report a case of a 32-year-old man whose wife and he were able to bear a child before the development of his epilepsy. With VPA monotherapy, the family were unable to conceive despite 4 years of unprotected intercourse. An infertility evaluation of the man revealed a very low sperm count of < 50,000/ml, no motile sperm, < 10% viability, and 100% with abnormal structure. Follicle-stimulating hormone, luteinizing hormone, and testosterone levels were normal. RESULTS: Felbamate (FBM) was initiated and VPA discontinued for improved seizure control. Within 4 months, the couple conceived their second child. A seminal analysis revealed a sperm count of > 16 million, 50% motility, 78% viability, and 72% with abnormal structure. CONCLUSIONS: One must be cautious in extrapolating from a case report, but these findings strongly suggest a direct effect of VPA on spermatic structure and function.

3/387. Intracytoplasmic sperm injection pregnancy with trisomy 20p and monosomy 22q in a newborn resulting from a balanced paternal translocation.

    In infertile men who carry a balanced reciprocal translocation, intracytoplasmic sperm injection (ICSI) may induce a pregnancy with an abnormal karyotype. This report describes a previously unreported paternal reciprocal translocation leading to a chromosomally unbalanced ICSI pregnancy. The triplet pregnancy resulted in 1 normal girl, 1 physically normal boy with the same balanced paternal translocation, and a severely malformed boy with trisomy 20p and monosomy 22q who died in the neonatal period.

4/387. Triplet pregnancy achieved through intracytoplasmic sperm injection with spermatozoa obtained by prostatic massage of a paraplegic patient: case report.

    spinal cord-injured men with ejaculation disorders can have children thanks to assisted reproduction techniques. spermatozoa from these patients are usually obtained through vibratory stimulation, electroejaculation or by puncturing the seminal duct or the testicle. We present the first published case, as far as we are aware, of spermatozoa obtained through prostatic massage of a paraplegic patient. Penile vibratory stimulation was unsuccessful in this patient. In-vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) with spermatozoa obtained through electroejaculation was performed at another centre but pregnancy was not achieved. Through prostatic massage, we obtained a total semen volume of 6 ml containing a total count of 12.32x10(6) spermatozoa (6.24x10(6) with tails), 8% of which had motility (graded and ); and 16% of which had normal morphology. The spermatozoa obtained were then used to perform IVF with ICSI and a triplet pregnancy was achieved. Prostatic massage appears to be an easy, non-traumatic and risk-free method to obtain spermatozoa from paraplegic patients.

5/387. Three-generation evaluation of Y-chromosome microdeletion.

    Sperm cells can be retrieved directly from the testis (testicular sperm extraction [TESE] procedure) and used for intracytoplasmic sperm injection (ICSI), circumventing underlying spermatogenetic defects. Thus, it is important that added information be available on the genetic defects in men undergoing TESE for the ICSI procedure and on the transmission of genetic factors associated with infertility to the offspring. We report a three-generation genetic analysis of a family with a case of male factor infertility. The proband, previously diagnosed as infertile, was physically examined and laboratory tested for gonadotrophic hormones, semen analysis, karyotype and Y-chromosome microdeletion screening in the blood and testis. The Y-chromosome microdeletion screening was performed by multiplex polymerase chain reaction with 20 Y-chromosome sequenced, tagged sites located at the y chromosome. A microdeletion including the AZF-c region was detected in the azoospermic patient. His father, four brothers, and three offspring born after ICSI also underwent Y-chromosome microdeletion screening. The genetic analysis of the male members of the patient's family did not reveal similar microdeletions. The newborn male was found to bear a Y-chromosome microdeletion similar to that of his father. The fertilization capacity of the proband testicular microdeleted spermatozoa by the ICSI procedure is described. The transfer of the genetic defect raises the possibility that the son will have the same fertility problem as his father.

6/387. Men with infertility caused by AZFc deletion can produce sons by intracytoplasmic sperm injection, but are likely to transmit the deletion and infertility.

    Deletion of the AZFc region of the y chromosome is the most frequent molecularly defined cause of spermatogenic failure. We report three unrelated men in whom azoospermia or severe oligozoospermia was caused by de-novo AZFc deletions, and who produced sons by intracytoplasmic sperm injection (ICSI). We employed polymerase chain reaction (PCR) assays to examine the Y chromosomes of their four infant sons. All four sons were found to have inherited the y chromosome deletions. Such sons are likely to be infertile as adults. This likelihood should be taken into account when counselling couples considering ICSI to circumvent infertility due to severe oligozoospermia or non-obstructive azoospermia.

7/387. Failure of pregnancy after intracytoplasmic sperm injection with decapitated spermatozoa: case report.

    The case of a couple with a history of long standing primary infertility is reported in which the man presented with a decapitated sperm defect. The woman had a normal history and presented with normal clinical characteristics. The couple underwent one unsuccessful conventional in-vitro fertilization (IVF). Subsequently, embryos were obtained and transferred after assisted fertilization attempts: in all, three subzonal inseminations and four intracytoplasmic sperm injections. A total of 49 mature oocytes was injected in both studies, 25 embryos obtained and 20 embryos transferred, three of them after freezing and thawing. Despite the good embryo morphology, implantation was unsuccessful and no pregnancy occurred. The failure of implantation may have resulted from an arrest in early embryonic development related to the sperm anomaly. One hypothesis is that transferred embryos may carry a chromosomal imbalance that prevents them from progressing to the blastocyst stage. Nevertheless, we cannot exclude the possibility that the woman is responsible for the implantation failure. Co-culture associated with a further attempt could provide information regarding the ability of embryos to progress to the blastocyst stage and implant.

8/387. Vigorous prostatic massage: a simple method to retrieve spermatozoa for intracytoplasmic sperm injection in psychogenic anejaculation: case report.

    A simple, non-invasive method to retrieve spermatozoa from patients with anejaculation is described. Three patients with psychogenic primary anejaculation were referred for intracytoplasmic sperm injection (ICSI). On the day of oocyte retrieval, vigorous prostatic massage was done. Examination of the expressed prostatic secretion revealed a sufficient number of motile spermatozoa in cases 1 and 3. In case 1, only one poor quality oocyte was obtained and ICSI was unsuccessful. spermatozoa were cryopreserved for future use. In case 2, no spermatozoa were retrieved by prostatic massage. A testicular biopsy was performed to retrieve spermatozoa for ICSI. Unfortunately no pregnancy resulted. In case 3, retrieved spermatozoa were successfully used for ICSI, and 19 ova were injected. fertilization occurred in 10 of these; seven were cryopreserved and three embryos were transferred. Ultrasound scan has confirmed a singleton pregnancy, which is ongoing. We conclude that vigorous prostatic massage could be an effective method of sperm retrieval for assisted conception in selected patients with anejaculation.

9/387. Unilateral obstruction of the vas deferens diagnosed by seminal vesicle aspiration.

    Causes of vasal obstruction include vasectomy, inguinal surgery, scrotal surgery, and congenital anomalies. The incidence of unilateral obstruction in various clinical situations is unknown because sperm from the contralateral testicle usually is present in the ejaculate. Vasography is the standard technique used to diagnose a unilateral vas deferens obstruction. We used the technique of seminal vesicle aspiration to accurately diagnose unilateral vas deferens obstruction in a man who had a previous inguinal hernia repaired with mesh. Surgical exploration confirmed the impression of vasal obstruction, and successful vasovasostomy was performed. We believe that seminal vesicle aspiration may be helpful in the diagnosis of unilateral vas deferens obstruction and has potential benefits over vasography.

10/387. male infertility associated with a unique 8;22 translocation.

    Proper evaluation of male infertility includes a careful history, physical examination, semen analysis, and karyotyping. Molecular cytogenetic analysis may also be necessary to further delineate the karyotype. Following the above approach, we found an apparently unique 8;22 translocation in a male patient with infertility but few other phenotypic manifestations. Delineating the exact genetic basis of infertility is important in view of the most recent advances in reproductive technology such as in vitro fertilization and intracytoplasmic sperm injection. patients utilizing these emerging techniques need to be properly counseled as to their risks of transmitting these chromosomal abnormalities to their offspring.
