Abstract:

Objective

To investigate the relationship between hepatitis B virus (HBV) infection and infertility, and to evaluate the impact of inactive HBV surface antigen (HBsAg) carriers on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes for infertile patients.

Methods

Total of 398 couples undergoing IVF in Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2018 to December 2019 were recruited; Among them, 71 couples were HBV seropositive (including female positive group with 32 cases and male positive group with 39 cases) and 327 couples were HBV seronegative controls. Age, duration of infertility, body mass index (BMI), basal follicle-stimulating hormone (bFSH), antral follicles count (AFC), anti-Müllerian hormone (AMH), total gonadotropin (Gn) dose, endometrial thickness, the number of oocytes, causes and types of infertility, fertilization rate, high-quality embryo rate, implantation and clinical pregnancy rates were compared between female of the two groups. Data of normal distribution (age, BMI, bFSH, Gn days, endometrial thickness) between the two groups were compared by independent sample t test, and data of skewed distribution (duration of infertility, AFC, AMH, total Gn dose, the number of oocytes) were compared by Wilcoxon rank sum test; the count data were analyzed by Pearson χ2 test (types of infertility, fertilization rate, high-quality embryo rate, implantation rate, pregnancy rate, miscarriage rate) or Fisher exact probability test (cause of infertility).

Results

Age (t = 1.95, P = 0.05), duration of infertility (Z =-0.8, P = 0.43), cause of infertility (χ2 = 4.06, P = 0.40), BMI (t = 0.68, P = 0.50), bFSH (t =-0.29, P = 0.97), AMH (Z =-1.45, P = 0.15) and AFC (Z =-0.80, P = 0.42) female between the two groups were without significant difference; In addition, the characteristics of IVF, including ovarian hyperstimulation regimen (χ2 = 2.83, P = 0.24), duration (t = 1.64, P = 0.10) and total dose of Gn (Z =-1.77, P = 0.08), endometrial thickness (t =-0.08, P = 0.94), number of oocytes (Z =-0.93, P = 0.35), fertilization rate (χ2 =2.44, P = 0.12) and high quality embryo rate (χ2 = 3.62, P = 0.06) were all without significant differences. Cases in HBsAg positive group and control group were transfered for 45 and 213 fresh embryo transfer cycles, respectively, and the implantation rate (χ2 = 0.00, P = 1.0), clinical pregnancy rate (χ2 = 0.47, P = 0.50) and miscarriage rate (χ2 = 0.11, P = 0.75) between the two groups were all without significant differences.

Conclusion

Inactive HBV surface antigen carriers had no significant effect on infertility and IVF/ICSI outcomes.
