Infertility in Female and Male Solid Organ Recipients - From Diagnosis to Treatment: An Up-To-Date Review of the Literature

Around 20% to 30% of patients after solid organ transplantation are of reproductive age. The estimated rate of infertility in this group is slightly higher than in the general population. Choosing the optimal moment for pregnancy in transplanted patients plays a pivotal role, regardless of the method of conception. The first part of this article presents an up-to-date review of the problem of infertility in female and male solid organ recipients, with special attention to the influence of specific immunosuppressive drugs on semen parameters. The second part discusses the current knowledge regarding infertility treatment and the results of assisted reproductive techniques in this specific group of patients.

Despite restoring gonadal functions after transplantation, the patients should be informed about possible negative effects of medications on fertility, course of pregnancy, and the fetus. Interdisciplinary care should always be provided for infertile graft recipients, especially women, as it ensures safety both for the graft and for the potential gestation. The process of infertility diagnosis and tools used for that purpose are the same in transplanted patients as in the general population. The treatment with assisted reproductive techniques is acceptable and gives favorable results as long as patients are managed rationally, with special attention paid to prevention of iatrogenic complications.

Comparison of sexual function changes in recipients of kidney transplant in females receiving kidney from the living donor and deceased donor

BACKGROUND AND AIM

Chronic renal failure can result in different sexual and reproductive problems for women. Due to lack of information about sexual dysfunction of women with transplanted kidney and superiority of either living or deceased donor, we designed this retrospective cohort study to compare sexual function changes in recipients of kidney transplant in two groups receiving kidney from the living donor and deceased donor using Female Sexual Function Index score.

METHODS AND MATERIALS

We included 55 female patients who underwent kidney transplant from 22 May 2015 to 22 May 2016 in Sina Hospital (Tehran, Iran). Laboratory factors, including creatinine, blood urea nitrogen, hemoglobin, fasting blood glucose, triglyceride, cholesterol, low-density lipoprotein, and high-density lipoprotein, were evaluated before and after the transplantation. Female Sexual Function Index questionnaire was used to evaluate sexual function of the patients before the transplant, 3 months after the transplant, and 9 months after the transplant.

RESULTS

Our results revealed that there is significant improvement in the Female Sexual Function Index score of the patients after the transplant (p-value < .001). However, we found no significant difference between the scores of the patients with living donor and deceased donor (p-value > .05). Patients' age, creatinine level, low-density lipoprotein, and diastolic blood pressure are negative predictors of Female Sexual Function Index scores.

α1-Acid glycoprotein and seminal parameter in chronic hemodialysis patients

INTRODUCTION

To find out the changes in seminal quality of hemodialysis chronic renal patients, we investigated the possible relationship between seminal parameter and seminal α1-acid glycoprotein levels in chronic hemodialysis patients.

METHODS

Prospective study of prevalence realized in the Hemodialysis Sector of the University Hospital of the University of Brasília, between July 2016 and December 2016. Men aged 18-60 years grouped into case groups (n = 81) represented by chronic hemodialysis patients and control group (n = 20) of healthy men without clinical or laboratory signs of infection and eugonadic. We performed a spermogram, hormonal profile, and assessment of leukocytes and seminal α1-acid glycoprotein level in the semen. The most appropriate statistical test was applied to verify differences and correlations between the studied variables.

RESULTS

The age in case and control is similar (49.47 ± 5.55 years vs 50.53 ± 4.24 years; p = 0.060). Mean level of α1-acid glycoprotein in human seminal plasma were not significantly different between case and control (48.52 ± 4.90 mg/L vs 46.33 ± 4.29 mg/L; p = 0.10) and between normosperm and oligosperm (47.76 ± 5.15 mg/L vs 49.48 ± 4.49 mg/L; p = 0.19). Mean level of α1-acid glycoprotein in human seminal plasma in the case group, which were classified into severe, moderate, mild, and normosperm, were similar to each other (p = 0.27) and did not correlate (p > 0.05) with the analyzed seminal parameters. All participants presented normal hormonal profile.

CONCLUSION

Results of this study suggest that the seminal α1-acid glycoprotein levels do not help in the initial evaluation of patients with seminal parameter changes.

In Vitro Fertilization After Renal Transplantation: A Single-Center Experience

INTRODUCTION

Although kidney transplantation often increases the chances of fertility, the rate of infertile patients is still high. In vitro fertilization promises successful results for infertile renal transplantation patients. The purpose of this study was to analyze the experience of a single center.

METHODS

Patients were invited to complete a survey for their obstetric history. Documentation review included demographic and clinical characteristics of patients, like procedure records, follow-up complications, immunosuppression maintenance protocols, and pregnancy outcomes.

RESULTS

Thirteen patients were reached to complete the survey. The mean age of patients was 33 ± 4 years at in vitro fertilization (IVF). The median duration of infertility was 2 years. Twenty-four IVF sessions were applied to these 13 women with renal transplantation. The procedure failed in 13 of these sessions; and 8 women achieved 11 clinical pregnancies. There were 3 miscarriages and 2 stillbirths. Six women had live births with no neonatal deaths. One patient had a graft rejection after the IVF procedure. Serum creatinine level increased more than 30% in 3 patients after the IVF procedure, while 9 patients had a minimal or no change.

DISCUSSION

In our study, we evaluated the records of 13 patients with renal transplantation who had IVF procedures. Fortunately, more than half of these patients had live births with no neonatal deaths. In our opinion, our findings show that IVF procedures can be accepted as a promising method in patients with renal transplantation and need a therapy for fertility. Moreover, a 25% live-birth rate per procedure is also a satisfactory result.
