The basic infertility investigation

Clinical significance of nonspecificity of antiphospholipid antibodies in recurrent abortions and unexplained infertility

Background:

Antiphospholipid antibodies (APLA) are acquired autoantibodies directed to phospholipids which are associated with slow progressive thrombosis and infarction of placenta. Infertility and recurrent pregnancy loss may occur because of impaired trophoblast function, placental infarction, and abnormal blood clotting.

Aim:

To evaluate APLA (IgG and IgM) in cases of infertility and recurrent abortions.

Materials and Methods:

A prospective study comprising 70 subjects was carried out. Fifty cases of unexplained infertility and recurrent abortions (25 each) constituted the study group. Twenty healthy multipara females of same reproductive age group constituted the control group. Venous blood samples were collected, and serum was analyzed for two types of APLA (IgG and IgM) by ELISA method.

Results:

The mean IgM and IgG levels in recurrent abortions group were 8.10 MPL-U/ml and 6.17 GPL-U/ml, respectively whereas in control group, the levels were 4.67 MPL-U/ml and 4.53 GPL-U/ml, respectively. The difference was statistically nonsignificant. The mean IgM and IgG levels in unexplained infertility group were 7.30 MPL-U/ml and 6.12 GPL-U/ml, respectively whereas in control group, the levels were 4.67 MPL-U/ml and 4.53 GPL-U/ml, respectively. Again the difference was statistically nonsignificant.

Conclusions:

The present study concludes that there is no significance of raised APLA in cases of infertility and recurrent abortions.

Injeção intracitoplasmática de espermatozóides: questões éticas e legais

O presente trabalho enfoca a técnica da fertilização in vitro por meio de injeção intracitoplasmática de espermatozóide (ICSI), abordando seus aspectos técnicos, bem como, questões éticas e legais que permeiam tal prática. Essa técnica se diferencia das demais por corresponder à injeção de um único espermatozóide vivo no citoplasma do ovócito, sendo uma das principais alternativas atuais para a infertilidade masculina, principalmente nos casais em que o homem tem uma diminuição significativa na quantidade ou na motilidade dos espermatozóides. Vale ressaltar, que as técnicas de reprodução assistida vêm se desenvolvendo rapidamente, dando ensejo a questões polêmicas, como as relativas ao início da vida embrionária e à manipulação genética, o que implica que se deve refletir sobre este assunto, levando-se em consideração os limites éticos. Nesse sentido, é preciso, urgentemente regulamentar o tema, mesmo com os progressos alcançados pelo novo Código Civil e pela Lei de Biossegurança.

An ultrasound-based approach to the assessment of infertility, including the evaluation of tubal patency

An optimal initial infertility investigation protocol would be a process that is diagnostically accurate, expeditious, cost-effective, reliable and as minimally invasive as possible. In addition, the investigation should provide the clinician with useful prognostic information regarding possible future treatment. At present, extensive use of invasive procedures such as diagnostic hysteroscopy and laparoscopy is the standard at many fertility centres. Recent advances in gynaecological ultrasonography have shown that ultrasound can replace routine invasive investigative procedures. An ultrasound-based approach would make the basic infertility investigation less time-consuming and less expensive, but at the same time more acceptable to the majority of patients. This chapter describes an ultrasound-based approach to the assessment of infertility. In addition, the role of ultrasonography for assessment of the pelvic organs as a basic part of the initial investigation of an infertile couple is discussed and compared to more traditional invasive methods.

Assessment of hyperactivation, acrosome reaction and motility characteristics of spermatozoa from semen of men of proven fertility and unexplained infertility

Semen from men of proven fertility was compared with that of men with unexplained infertility to determine differences in spermatozoal functions such as hyperactivation and acrosome reaction and spermatozoal motility characteristics. The hyperactivated spermatozoa in both groups could be visualised on the monitor of the Computer Assisted Semen Analyser and they exhibited 'circling', 'thrashing', 'starspin' and 'helical' motility patterns and the mean hyperactivation rates were not significantly different. However, 20% of the men with unexplained infertility did not exhibit hyperactivation compared to only 4% in the fertile group. Furthermore, the semen from infertile men when evaluated for hyperactivation could be categorised into two groups with those having lower hyperactivation (< 10% or < 6% after 4 and 6 h of incubation respectively), forming the first group, and those having a higher hyperactivation rate constituting the second group. In the fertile men such distinct groups were not visible and the percentage hyperactivation ranged from 1 to 16%. No significant differences were observed in the rate of acrosome reaction of fertile and unexplained infertile men. The non-hyperactivated spermatozoa from unexplained infertile men showed a significant increase in path velocity (VAP), curvilinear velocity (VCL) and amplitude of lateral head displacement (ALH) and a decrease in linearity (LIN) and straightness (STR) compared to spermatozoa from fertile men. Furthermore, the hyperactivated spermatozoa from infertile men also showed an increase in progressive velocity (VSL) (only after 2 h of incubation) and LIN and decrease in ALH and beat cross frequency (BCF) compared to spermatozoa from fertile men. The results are discussed in the light of the importance of the above spermatozoal functions and spermatozoal parameters in fertilization.

Infertility in women with pemphigus vulgaris and other autoimmune diseases

BACKGROUND

Pemphigus vulgaris (PV) is an autoimmune disease. Autoimmune diseases may adversely affect reproductive function and could result in infertility.

OBJECTIVE

Our purpose was to describe nine young women with PV and infertility.

METHODS

A retrospective study was performed. Clinical characteristics, immunopathologic features, treatment, clinical course, and long-term follow-up were determined.

RESULTS

Eight of nine patients were unable to become pregnant. One patient became pregnant during a period of remission. In eight of the nine patients, the cause of infertility was ovarian. Anti-sperm antibodies were present in two of the patients.

CONCLUSION

Some patients with PV may have infertility. No definitive conclusion about the frequency of infertility in these patients or its relation to PV can be drawn. However, these observations indirectly demonstrate that there may be important interactions between the immune and hormonal systems.

Practice patterns among reproductive endocrinologists: the infertility evaluation

OBJECTIVE

To determine how board-certified reproductive endocrinologists vary in their approach to the clinical tests performed on the infertile couple.

DESIGN

A cross-sectional study to assess differences in the approach to evaluating the infertile couple.

SETTING

A population-based national survey.

PARTICIPANT(S)

United States board-certified reproductive endocrinologists.

MAIN OUTCOME MEASURE(S)

The frequency of clinical tests and evaluation procedures by physician age, sex, size and setting of practice, institutional affiliation, and geographic location.

RESULT(S)

The overall response rate was 84%. Although the majority of practitioners routinely order a semen analysis (99.9%), an assessment of ovulation (98%), a hysterosalpingogram, (HSG; 96%), laparoscopy (89%), and a postcoital test (PCT, 79%), there was less agreement regarding hormonal testing (range, 22% [LH] to 66% [PRL]), use of pelvic ultrasounds (55%), hysteroscopy (53%), cervical cultures (range, 24% to 54%), and antisperm antibody testing (24%). Compared with male colleagues, female physicians order two to three times more cervical cultures and endometrial biopsies. Serum hormonal testing was two to three times more commonly ordered by younger (< 40 years) compared with older physicians, and physicians in private practice twice as frequently ordered hormonal testing, cervical cultures, PCTs, and antisperm antibody studies compared with their academic-affiliated colleagues. Western U.S. physicians order hormonal tests and cervical cultures 50% less often than their midwest and eastern counterparts.

CONCLUSION(S)

Trained specialists rely heavily on five "traditional" infertility tests: semen analysis, an assessment of ovulation, HSG, laparoscopy, and PCT. With regard to additional modes of testing, there is marked variability by physician sex, age, type of practice, and geographic location.

Subfertility in the era of assisted reproduction: changes and consequences

OBJECTIVE

To review the major changes that have occurred during the last decade of assisted reproduction technology (ART) practice, looking at the various conditions that cause subfertility.

DESIGN

A short review describing the progress that has been made during the last decade of ART practice, analyzing the various conditions that cause subfertility, is presented. The efficacy of ART as a treatment of these conditions is discussed.

CONCLUSIONS

Assisted reproductive technology currently is used for a wide range of indications and has become an acceptable tool in the treatment of subfertile couples. Yet, there is an ongoing debate regarding the effectiveness of ART versus conventional treatment for the various conditions that cause subfertility. The effectiveness of IVF in terms of pregnancy rate (PR) was demonstrated only for patients with severe bilateral tubal disease and male subfertility. For couples with other causes of infertility the differences in PRs do not reach statistical significance, and the efficacy of IVF has not been demonstrated clearly to date. Moreover, much of the discussion about management of subfertility has centered on costs of ART and the cost-benefit of ART versus conventional therapy for subfertility. It has been shown that, in women with unexplained infertility, menotropin treatment is as successful, less expensive, and carries a smaller risk than the surgical approach used in ART. However, the exact role of ART in the management of polycystic ovarian syndrome, immunological infertility, and endometriosis still is to be determined. Yet, as embryo implantation after ART still is considerably lower than that of fertile couples who conceive naturally, we expect that the next major thrust improving the effectiveness of ART will occur after future elucidation of factors influencing embryonic implantation.

Radiological evaluation of infertility

With unwanted infertility on the rise, the radiologist is becoming increasingly involved both in the diagnosis and treatment of these patients. Assessment of the six most common factors causing infertility should be performed during the initial clinical evaluation. These six factors include the cervical factor, endometrial-uterine factor, tubal factor, ovarian factor, peritoneal factor, and male factor. Each of these groups will be discussed in detail with special attention to optimal methods of diagnosis. Hysterosalpingography and ultrasound play the major roles in evaluation; however, there is an important emerging role for newer techniques such as MRI and selective fallopian tube catheterization.

Score prognosis for the infertile couple based on historical factors and sperm analysis

OBJECTIVE

To identify variables, obtained from historical factors and sperm analysis, associated with greater chances of pregnancy in infertile couples.

METHODS

The study was carried out in Córdoba, Argentina. The characteristics of 247 couples consulting for infertility who achieved pregnancy within 3 years of their first visit were compared with those of 312 couples who did not become pregnant. We evaluated the relationship between the age of the woman and her partner, the type and duration of infertility, length of the last three menstrual cycles, history of pelvic surgery in the woman, and testicular volume, sperm density, motility and morphology in her partner, and the achievement of pregnancy. For the analysis, logistic regression was used.

RESULTS

Six variables had a predictive value: sperm morphology, the woman's age, type and duration of infertility, her history of pelvic surgery, and duration of menstrual cycles.

CONCLUSIONS

The best prognosis for future fertility in infertile couples is correlated with a higher percentage of normal sperm morphology, younger woman's age, secondary infertility, fewer years of infertility, negative history of pelvic surgery, and abnormal menstrual cycles.

Quality of care for infertility patients. An evaluation of a plan for a hospital investigation

AIM OF STUDY

In this study we assessed the quality of health care for infertile patients as expressed by the patients themselves. The implementation of the existing structured plan for infertility investigation and treatment was also reviewed. DESIGN AND DATA: The sample consisted of all 361 women registered with an infertility diagnosis during 1982 at Rikshospitalet. Their medical records were reviewed in 1988. The process and outcome of the investigation as it appeared was analyzed for each individual patient. A structured questionnaire was distributed to the patients in 1988 and 72.6% responded. The questions included several items on outcome and personal experience of the treatment in the hospital.

RESULTS

Data from the medical records show that the medical investigation lasted three years on average. The records often showed evidence of discontinuity of the process. The mean number of consultations was eight (range 1-28). An average of one new doctor for each consultation was involved in the investigation. One third of the patients left the investigation without a noted definite termination of the treatment process. According to the questionnaire around 40% had delivered at least one child, while 30% had adopted. Of those who got a biological child, two thirds were satisfied with the clinical treatment efforts of the medical staff. Less than half of those who did not become pregnant were satisfied. Independent of outcome, 70% were dissatisfied with the emotional support during the investigations, and nearly 90% felt that waiting lists were too long. More than half expressed a need for professional psychological counselling.

CONCLUSIONS

The study shows that medical records and service organizations do not meet the need for continuity in treatment nor research and evaluation requirements. We suggest that more emphasis should be devoted to planning of the services. They should be improved with regard to quality in medical handling as well as emotional counselling.
