Abstract
The birth of reproductive rheumatology as a subject of interest in rheumatology has led to improvement of clinical care for patients living with autoimmune rheumatic diseases and paved the way towards setting a specialized pregnancy service within the standard rheumatology practice. In contrast to women, where there has been wealth of literature regarding pregnancy, lactation, and birth outcomes, there is not as much focusing on male sexual health and outcomes among inflammatory arthritis patients. Challenges such as decrease ability to conceive, impaired fertility, erectile dysfunction, and other sexual problems have been raised by male patients living with autoimmune rheumatic diseases. This broad scope gives the reproductive health concept in men another expansion with views to include sexual health problems screening among men attending the standard outpatient rheumatology clinics. This article adds to the paucity of real-life experience and aims at discussing the sexual health from the men perspective and provides a practical approach towards screening, and assessment of men living with autoimmune diseases in standard day to day practice.

Relationship between natural and intrauterine insemination-assisted live births and the degree of sperm autoimmunisation. Hum Reprod 2020; 35:1288-1295. [PMID: 32358600 DOI: 10.1093/humrep/deaa070] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 03/04/2020] [Indexed: 11/12/2022] Open
Abstract
STUDY QUESTION What is the relationship between the degree of sperm autoimmunisation, as assessed by IgG-mixed antiglobulin reaction (MAR) test, and natural and intrauterine insemination (IUI)-assisted live births? SUMMARY ANSWER Compared with a lower degree of positivity (50-99%), a 100%-positive MAR test was associated with a much lower occurrence of natural live births in infertile couples, who could be successfully treated with IUI, as first-line treatment. WHAT IS KNOWN ALREADY The World Health Organization (WHO) has recommended screening for antisperm antibodies, through either the IgG-MAR test or an immunobead-binding test, as an integral part of semen analysis, with 50% antibody-coated motile spermatozoa considered to be the clinically relevant threshold. However, the predictive value of the degree of positivity of the MAR test above such a cut-off on the occurrence of natural pregnancies remains largely undetermined. Furthermore, the effectiveness of IUI in cases of strong sperm autoimmunisation is not yet well-established. STUDY DESIGN, SIZE, DURATION This was a retrospective cohort study on 108 men with a ≥50%-positive MAR test, where the couple had attended a university/hospital andrology/infertility clinic for the management of infertility from March 1994 to September 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS The IgG-MAR test was carried out as an integral part of semen analysis. The patients were divided into two groups: 100% and 50%-99%-positive MAR test. The post-coital test (PCT) was performed in all the couples, and IUI was offered as the first-line treatment. Laboratory and other clinical data were retrieved from a computerised database. Data on subsequent pregnancies were obtained by contacting patients over the telephone. MAIN RESULTS AND THE ROLE OF CHANGE A total of 84 men (77.8%) were successfully contacted by telephone, and they agreed to participate. Of these, 44 men belonged to the group with a 100%-positive MAR test, while 40 showed lower MAR test positivity. The couples with a 100%-positive MAR test showed a natural live birth rate per couple (LBR) that was considerably lower than that observed with a lower degree of positivity (4.5% vs. 30.0%; P = 0.00001). Among the clinical variables, a significant difference between the two groups was observed only for the PCT outcome, which was poor in the 100%-positive MAR test group. Better PCT outcomes (categorised as negative, subnormal and good) were positively associated with the occurrence of natural live births (6.3, 21.7 and 46.2%, respectively; P = 0.0005 for trend), for which the sole independent negative predictor was the degree of sperm autoimmunisation. IUI was performed as the first-line treatment in 38 out of 44 couples with a 100%-positive MAR test, yielding 14 live births (36.8%). In couples with lower MAR test positivity, the LBR after IUI (26.9%) was similar to the natural LBR in this group (30.0%). LIMITATIONS, REASONS FOR CAUTION Given the retrospective nature of the study, we cannot exclude uncontrolled variables that may have affected natural pregnancies during the follow up or a selection bias from the comparison of natural live births with those after IUI. WIDER IMPLICATIONS OF THE FINDINGS The routine use of the IgG-MAR test in the basic fertility workup is justified as it influences decision making. A 100%-positive IgG-MAR test can represent the sole cause of a couple's infertility, which could be successfully treated with IUI. On the other hand, a lower degree of positivity may only represent a contributing factor to a couple's infertility, and so the decision to treat or wait also depends on the evaluation of conventional prognostic factors including the PCT outcome.

Abstract
BACKGROUND Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial related to particularities of each disease. This review highlights how rheumatic diseases and their management affect testicular function and male fertility. MATERIALS AND METHODS A systematic review of literature of all published data after 1970 was conducted. Data was collected about fertility abnormalities in male patients with systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, ankylosing spondylitis, Behçet disease and gout. Two independent researchers carried out the search in online databases. RESULTS A total of 19 articles were included addressing the following diseases: 7 systemic lupus erythematosus, 6 Behçet disease, 4 ankylosing spondylitis, 2 rheumatoid arthritis, 2 dermatomyositis and one gout. Systemic lupus erythematosus clearly affects gonadal function impairing spermatogenesis mainly due to antisperm antibodies and cyclophosphamide therapy. Behçet disease, gout and ankylosing spondylitis patients, including those under anti-TNF therapy in the latter disease, do not seem to have reduced fertility whereas in dermatomyositis, the fertility potential is hampered by disease activity and by alkylating agents. Data regarding rheumatoid arthritis is scarce, gonadal dysfunction observed as consequence of disease activity and antisperm antibodies. CONCLUSIONS Reduced fertility potential is not uncommon. Its frequency and severity vary among the different rheumatic diseases. Permanent infertility is rare and often associated with alkylating agent therapy.

Abstract
Anti-sperm antibodies (ASA) are an important cause of immunological infertility. The objective of this study was to identify immunodominant sperm antigens recognized by anti-sperm antibodies (ASA) in serum samples of infertile men, women and vasectomized men. High-resolution two-dimensional gel electrophoresis was employed to separate human sperm proteins using isoelectric focusing (IEF) or nonequilibrium pH gradient electrophoresis (NEPHGE), followed by PAGE and Western blotting. Serum samples from five infertile male and five infertile female subjects that contained ASA as assayed by the immunobead binding test (IBT), were analyzed by Western blotting using NEPHGE gels followed by enhanced chemiluminescence (ECL) to identify the basic sperm antigens reactive to the sera. Serum samples from five fertile male and five fertile female subjects that were ASA-negative by IBT were used as controls. Serum samples from six vasectomized men collected before vasectomy and at different time intervals until 6 months after vasectomy were analyzed by Western blotting using IEF gels. The ECL blots were analyzed to compare immunoreactivity between serum samples from fertile and infertile subjects and identify antigens unique to sera of the infertile subjects. Similarly, immunoreactivity between serum samples from pre- and post-vasectomy was compared to identify antigens unique to sera collected following vasectomy. Five allo-antigenic basic protein spots were recognized by sera from infertile males but not from fertile subjects. Five sperm iso-antigenic basic spots were recognized by infertile female subjects. Two among six of the vasectomized men's sera showed a difference in the Western blot profile 6 months after vasectomy, recognizing at least one new protein spot in each case when compared to pre-vasectomy sera. The acrosomal protein SP-10 was identified as an alloantigen recognized by a post-vasectomy serum. Molecular identities of the known allo- and iso-antigens identified in this study and in previous studies from this laboratory are reviewed and discussed.

Abstract
To identify novel sperm alloantigens relevant to immune infertility, sera from infertile men containing antisperm antibodies (ASA) were employed on 2-D immunoblots of human sperm proteins. An immunoreactive protein spot (MW: 44 kDa, pI: 4.5) was microsequenced and the related cDNA was cloned yielding a 309 amino acid sequence corresponding to a gene currently annotated in Genbank as TSGA2 homolog (mouse) to signify 'testis specific gene A2'. In Genbank the protein deduced from this gene is currently named human meichroacidin, an orthologue of meichroacidin previously identified in mouse spermatocytes. Human TSGA2 mapped to chromosome 21q22.3. Human meichroacidin (hMCA) contained a single potential tyrosine phosphorylation site and five casein kinase phosporylation motifs. The N-terminus contained a Membrane Occupation Recognition Nexus (MORN) motif found in the lipid kinase-phosphatidylinositol 4-phosphate 5-kinase (PIP5K) family and junctophilins. However hMCA lacked the characteristic kinase homology domain of PIP5K. Northern blot analysis revealed 1.5 kb hMCA transcripts in testis and trachea with lower levels in thyroid and spinal cord. A semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis demonstrated occurrence of the mRNA messages in all the ciliated tissues tested with highest levels of messages in testis and trachea. Western blot analysis showed the presence of hMCA protein in brain, thyroid and trachea at the identical mass, 44 kDa, as in human testis. However, this immunoreactive pattern differed from that of sperm in which a 38 kDa form was also evident suggesting that hMCA undergoes proteolytic processing. In human testis, hMCA localized to the tails of developing spermatids and did not localize to the nucleus of either spermatocytes or spermatids. EM immunocytochemistry localized hMCA within the radial spokes of the axonemal complex of the sperm flagellum, and immunofluorescence studies revealed h-meichroacidin in the cilia of epithelial cells in the trachea and ependyma. Bioinformatic identification of orthologues of meichroacidin in several lower organisms including ciliates and flagellates suggest the protein plays a role in flagellar motility across phyla. We propose the term radial spoke protein 44 as an accurate designation, preferable to human meichroacidin because it denotes the restricted localization of the protein to the radial spokes of the axonemes of both sperm and cilia. Further, since the human gene is expressed in brain, thyroid, trachea and lung in addition to testis, we suggest that the gene name be changed from TSGA2 [testis specific gene A2] to radial spoke protein 44 [RSP44].

Abstract
Progress in diagnosis of infertility, has been dramatically increased during the past decades with changes occurring in virtually all aspects of infertility research, thus providing innovative diagnostic testing and sophisticated instrumentation for improved management and treatment of infertility. There are about 50% of infertile couples who are suffering because of male infertility. Semen examination is a basic investigation for these infertile couples. It not only reveals the quantity and quality of sperm but also the quality of the seminal plasma, which is essential for normal sperm function. In this review, the recent advancement in investigation procedures has been analyzed which are very important in clinical practice to (a) evaluate the sperm fertilizing ability (Acrosin, aniline blue, HOS), (b) characterization of male accessory sex glands secretions (Fructose, alpha-glucosidase, PSA) and (c) the management of azoospermic patients. It is believed that use of such diagnostic procedures will facilitate wide selection of patients for whom an effective therapy might be then possible.

Abstract
The success of a comprehensive office-based evaluation of male-factor infertility depends on the physician's thorough understanding of risk assessment in the history, identification of pertinent physical examination findings, and correct assessment of laboratory data. Office-based ultrasonographic techniques have already increased the urologist's ability to visualize suspected anatomic abnormalities, and the use of functional tests of sperm has given greater depth to the limited, but essential, prognostic capabilities of the routine semen analysis.

Abstract
Evaluation of infertile couples has revealed that male factor infertility contributes to the problem in up to 50% of cases. Evaluation of the male infertility patient may include endocrine studies, sophisticated semen testing, and select radiographic studies. Reversible and life-threatening causes of male infertility should be identified before proceeding directly to assisted reproductive technology. For cases with irreversible causes, a proper evaluation can identify patients who may be treated with the breakthrough method of intracytoplasmic sperm injection. Many men who were previously thought to be infertile may now initiate their own biologic pregnancies. This article emphasizes the essentials of the contemporary approach to evaluating the male factor in an infertile couple.

Abstract
PROBLEM To determine (1) the incidence of cervical mucus anti-sperm antibodies in infertile women, and (2) the results of treatment by intrauterine insemination. METHOD Cervical mucus was collected the morning after urinary LH surge occurred from 153 consecutive women being treated for unexplained infertility with intrauterine insemination. Immunobead testing for IgG, IgA, IgA1, and IgA2 was performed with only actively motile sperm being counted. RESULTS Overall, 23/153 (15.0%) of cervical mucus samples were positive for anti-sperm antibodies: 9/23 (39.1%) were only IgA-positive (62% IgA1-positive, 38% IgA2-positive), 11/23 (47.8%) were only IgG-positive, and 3/23 (13.0%) were positive for both IgA and IgG. Insemination resulted in a pregnancy in 6/23 (26.1%) of women with cervical mucus anti-sperm antibodies after 1-3 cycles. CONCLUSIONS Testing for cervical mucus anti-sperm antibodies should be performed in cases of "unexplained" infertility, and intrauterine insemination may be an effective treatment, resulting in pregnancies in over one-fourth of couples.

Abstract
A method has been developed to establish lines of transformed lymphocytes able to produce in vitro the same anti-sperm antibodies as those naturally occurring in immuno-infertile individuals. We utilized lymphocytes from a male donor whose serum contained anti-sperm antibodies of the IgG class up to the dilution 1:10,000, as detected by means of immunobead binding. T lymphocytes were separated from B lymphocytes using magnetic beads coated with anti-T antibody. B lymphocytes were then placed at a concentration of 5 x 10(6)/ml in a 96-well plate, stimulated with phytohaemagglutinin (PHA) and transformed with Epstein-Barr virus. After a few days, only transformed cells continued growing and these were collected. The supernatant was tested for production of anti-sperm antibodies and those transformed lymphocytes shown to be synthesising antibodies directed against the sperm head and the tail were cloned. We obtained a clone of cells producing antibodies of the IgG1 class directed against the head of the spermatozoon. This oligoclonal antibody (F6) recognized a 58-kDa band from a lysate of sperm membranes and was able to reduce the penetration of zona-free hamster oocytes by capacitated spermatozoa.

Abstract
OBJECTIVE To compare IUI with timed intercourse in men receiving oral steroid therapy for the treatment of infertility associated with antisperm antibodies. DESIGN A prospective, randomized, cross-over trial. SETTING All patients were managed and treated at the Andrology Unit, Churchill Hospital, Oxford, United Kingdom. PATIENTS AND PARTICIPANTS Thirty males who were found to have antisperm levels of > or = 50% [using the indirect immunobead test with isotypes immunoglobulin (Ig) G, IgA, and IgM (GAM) beads] in either seminal plasma or serum on routine testing were recruited with their partners into the study. MAIN OUTCOME MEASURES Antisperm antibody levels in seminal plasma and serum, sperm parameters, conception rates, and pregnancy outcome. RESULTS There was a statistically significant reduction in seminal plasma antisperm antibody levels associated with steroid therapy. There was a significant improvement in certain spermatozoan parameters during steroid therapy. The cumulative pregnancy rate over four cycles of IUI was 39.4%. The cumulative pregnancy rate over four cycles of natural intercourse was 4.8%. There was a significantly higher chance of achieving a pregnancy with IUI. CONCLUSION Intrauterine insemination significantly improves the chance of achieving a conception when used as an adjuvant therapy to cyclical intermediate dose steroid therapy. Antisperm antibody levels in seminal plasma are significantly reduced during treatment with cyclical intermediate dose steroid therapy, although levels in serum appear to be unaffected. Cyclical intermediate dose steroid therapy significantly improves certain sperm parameters but, when used in isolation, is associated with a low pregnancy rate.

Abstract
OBJECTIVE To discuss the role of antisperm antibodies (Ab) in infertility, including proposed mechanisms of antisperm Ab formation, assays for their detection, and treatments for immune-mediated infertility. DESIGN Major studies in the published literature and data from The University of Texas Southwestern Medical Center, Division of Reproductive Endocrinology. Reports were reviewed that investigated the development and impact of alloimmunity and autoimmunity to spermatozoa in men and alloimmunity in women and the current methods of treatment for resultant subfertility. RESULTS The exposure of spermatozoal antigens to the mucosal and systemic immune systems results in development of immunity to a multiplicity of spermatozoal epitopes. The evaluation of studies that examine the role of antisperm Ab in infertility is complicated by the lack of standardization of antisperm Ab assays and the difficulty in identifying those epitopes for antisperm Ab binding that are responsible for subfertility. Sperm-associated antisperm Ab and antisperm Ab in cervical mucus (CM) reduce sperm mobility and may also impair sperm-ovum interaction. The clinical significance of serum antisperm Ab in both men and women, however, is controversial. Current therapy for antisperm Ab associated infertility is empiric and largely unproven. CONCLUSIONS Antisperm Ab on the sperm surface and in CM are implicated in the pathogenesis of a subset of patients with infertility. Further studies that determine the clinically relevant sites of antisperm Ab interaction will aid in directing the treatment of subfertility mediated by antisperm Ab.

Abstract
During a 6-month period 59 semen specimens were subjected to the direct immunobead test and 12 were positive (15% or more of sperm bound by IgA or IgG to the head, mid piece or principal piece of the tail, for an incidence of 20%). Mean motility and forward progression (scale of 0 to 4) were 47% (range 10 to 80) and 1.7 (range 1 to 3), respectively, in the positive test group, whereas these values were 53% (range 1 to 90) and 2.2 (range 1 to 3), respectively, in the negative test group. Sperm penetration assay was performed on 11 of the 12 direct immunobead test positive specimens. A normal sperm penetration assay score was noted in 5 of the 11 specimens (46%), a subfertile score in 4 (36%) and an infertile score (no penetrations) in 2 (18%). The incidence of scores in these 3 subcategories of fertility status in the direct immunobead test positive group did not differ significantly from distribution of scores from all 87 sperm penetration assays performed at our laboratory during the same period: normal--39 of 87 (45%), subfertile--35 (40%) and infertile--13 (15%). Furthermore, there was no pathognomonic binding pattern for those antibody positive patients with subfertile or infertile scores. In conclusion, sperm antibody positivity is typically independent of egg penetration ability, there is no pathognomonic antibody binding pattern for poor egg penetration and there is a tendency for antibody positive sperm to have a lower percentage of motility and forward progression.

Abstract
PROBLEM The prevalence of anti-sperm antibodies (ASAs) in the general population is 0 to 2%; the prevalence in infertile men is much higher at 7 to 26%. However, the role of ASAs in male infertility remains controversial to date. Although several risk factors for ASA development have been defined (such as testicular torsion, varicocele, cryptorchidism, vasectomy, and genital tract infection), there are no specific indications for ASA testing. METHOD In order to examine if a single parameter exists identifying patients with elevated ASA titers, serum ASA testing was performed with an enzyme-linked immunosorbent assay (ELISA) in 226 consecutive male patients. The new assay, synchron ELISA (Synelisa) used in our study represents a new type of ELISA without fixation of the sperm surface antigens by formaldehyde or glutaraldehyde. Therefore, the quantitative assay is highly sensitive and reproducible since the structure of sperm surface antigens is not altered by the fixation process. CONCLUSIONS The prevalence of ASAs in this population was 14%, while the prevalence of the control group was 2.5%. Of all factors analyzed only a history of vasectomy, an acute epididymitis, and an abnormal result in the bovine mucus penetration test was associated with elevated ASA titers (P < .001). In addition, we could demonstrate a time related formation of ASAs in men after vasectomy.

Abstract
Although there are many causes of the production of antispermatozoal antibodies, there are still unknown aetiological factors. Antispermatozoal antibodies were investigated in the postoperative period in 25 infertile men with varicocele whose antispermatozoal antibody tests were negative in the preoperative period. Antispermatozoal antibodies were found in the serum in 4 of the 25 (16%) infertile men after varicocele operation. Postoperative genital infections were detected in 6 patients and antispermatozoal antibodies were present in only 2 of them. The correlation between these antibodies and varicocele has been demonstrated but there is no report on the association of antibodies with varicocelectomy in the literature to date.

Abstract
PROBLEM The presence of anti-sperm antibodies (ASA) in female serum has been correlated with decreased fertilization in the in vitro fertilization (IVF) program; however, the impact of each type of ASA (IgG, IgA, IgM) is not known. METHOD To clarify the role of each ASA subtype, the immunobead binding technique was used to identify IgG, IgA, and IgM ASA in the female sera and on the spermatozoa from 137 couples undergoing the IVF program. RESULTS Couples with ASA on spermatozoa had a lower fertilization rate and lower number of transferred embryos: and IgG was the major immunoglobin involved. Couples with ASA in female sera showed significant decreases in the rates of fertilization, cleavage, and number of transferred embryos only when IgM was detected, but not IgG or IgA. However, the presence of IgA ASA in female sera was only associated with a decrease in pregnancy rate, although the number of transferred embryos was not reduced. CONCLUSION These findings suggest that ASA can influence the results of IVF and that the specific effect is dependent upon the subtypes of ASA.

Abstract
Anti-sperm antibodies were eluted from the sperm cell fraction of autoimmune human ejaculates and transferred onto normal motile spermatozoa. The movement and the acrosomal status of these antibody-coated spermatozoa were evaluated after incubation in a capacitating medium. The amplitude of lateral head displacement (ALH) and the straight line velocity (VSL) were analyzed using an HTM automated motility analyser. Acrosomal loss was monitored by an FITC-conjugated lectin binding technique. During the 6-h incubation in BWW-BSA medium, antibody-free and antibody-coated spermatozoa exhibited significant changes of ALH and VSL distribution that evolved differently in the two populations. The dynamics of sperm movement in control spermatozoa were apparently modified by the presence of antibodies on the sperm membrane. The low percentage of spontaneous acrosomal loss obtained in control populations, even after 20 h of incubation, was not modified by the presence of antibodies on spermatozoa. However, the same antibodies decreased the acrosomal loss induced by a calcium ionophore after 3 h of incubation in capacitating conditions. These results suggest that sperm capacitation and acrosome reaction, considered as essential for successful fertilization, can be altered by antisperm antibodies present on human ejaculated spermatozoa.

Abstract
Sperm-bound immunoglobulins were found in 27 (32%) of 84 infertile men with palpable varicoceles. These men were divided into two groups based on the presence (group I; 32%) or absence (group II; 68%) of sperm-bound immunoglobulins, as measured by an enzyme-linked immunosorbent assay. Circulating antisperm antibodies were identified in 52% of patients with sperm-bound immunoglobulins and 14% of group II patients. The presence of sperm-bound immunoglobulins was associated with a small but significant decrease in both sperm concentration and motility. Sperm-bound immunoglobulins are present in a greater percentage of infertile men with varicoceles than infertile men without varicoceles. Their presence may be a marker for damage to the seminiferous epithelia in men with varicoceles and may also contribute to varicocele-associated infertility.

Abstract
Twelve couples who underwent infertility investigations at the Universitas Hospital in Bloemfontein were examined using several tests: postcoital (PCT), sperm-cervical-mucus-contact (SCMC-T), indirect immunobead (IBT), tray-agglutination (TAT), and sperm-immobilization procedures (SIT). Two factors played a role during the immunologic evaluation of a couple: semen quality and the intensity of the antibody in the cervical mucus or seminal plasma.

Abstract
Immunization of male and female animals with extracts of whole sperm cells is known to cause infertility. Also, men and women who spontaneously produce antisperm antibodies are infertile but otherwise healthy. Although the critical sperm antigens are unknown, these observations have led to the proposal that sperm proteins might be useful in the development of a contraceptive vaccine. The guinea pig sperm surface protein PH-20 is essential in sperm adhesion to the extracellular coat (zona pellucida) of the egg, a necessary initial step in fertilization. Here, we report that 100% effective contraception was obtained in male and female guinea pigs immunized with PH-20. Antisera from immunized females had high titres, specifically recognized PH-20 in sperm extracts, and blocked sperm adhesion to the egg zona pellucida in vitro. The contraceptive effect was long-lasting and reversible: immunized females, mated at intervals of six to fifteen months after immunization, progressively regained fertility.

Abstract
Sixty-five infertile women had a conventional postcoital test (PCT), a computerized postcoital test (cPCT), and sperm antibody testing. Twenty-four women had good cervical mucus and good PCT sperm motility (group 1), 23 had poor cervical mucus and poor PCT sperm motility (group 2), and 18 had good cervical mucus but poor PCT sperm motility (group 3). The percentage of motile sperm, mean linearity, and the motility index of sperm by cPCT also were decreased in groups 2 and 3 (p less than 0.001) in contrast to group 1. A reduced PCT sperm count was significantly associated with positive titers of antibodies to autologous sperm in the husbands' serum, whereas a reduced PCT motility correlated with high titers of cytotoxic antibodies to husbands' sperm in the wives' serum and cervical mucus. An increased percentage of vibratory sperm at PCT correlated with elevated titers of cytotoxic antibodies to husbands' sperm in the wives' serum and cervical mucus, and hemagglutinating (r = 0.44; p less than 0.001) and immunofluorescent IgA antibodies to husbands' sperm (r = 0.47; p less than 0.001) in the cervical mucus. Mean swimming speed of sperm by cPCT correlated inversely with cytotoxic and hemagglutinating antibody titers to husbands' sperm, and immunobead-binding IgM and immunofluorescent IgG, IgA, and IgM (r = 0.52; p less than 0.001) antibodies to sperm in the seminal plasma. Motility indices correlated inversely with cytotoxic antibody titers to husbands' sperm in the wives' serum, and hemagglutinating antibody titers to husbands' sperm in cervical mucus. The predictive values of PCT and cPCT for the presence of cytotoxic and immunofluorescent IgA antibodies to autoimmune husbands' sperm were 76% and 71%, respectively, in the serum and 85% and 75%, respectively, in the cervical mucus of the wives. The predictive value of PCT and cPCT for immunobead-binding and immunofluorescent IgM antibodies to sperm in the wives' serum was 71%. Computerized PCT measures more sperm characteristics than PCT, although it is in general agreement with PCT.

Abstract
Immunoglobulin-specific assays are currently available for detection of patients with antibody-mediated infertility. Care must be taken in insuring that the correct immunoglobulin class is assayed, the assay is directed to the possible interaction of antibodies and sperm in the male or female genital tract, and the antigen employed will not detect antibodies against antigens not found on the plasma membrane of living sperm.
