Female Autologous Platelet-Rich Plasma (PRP) Co-incubation With Husband's Sperm

Reproductive Issues

Hypotheses: We hypothesize that infertility patients undergoing IUI who receive female autologous platelet-rich plasma (PRP) co-incubation with husband's sperm would have higher clinical pregnancy rate. Aims: * To determine if the use of female autologous platelet-rich plasma (PRP) co-incubation with husband's sperm in the IUI will show higher clinical pregnancy rate (CPR). Clinical pregnancy rate as determined by a positive serum beta-hCG test result and at least one gestational sac at 6 weeks gestation * To assess the safety of female PRP co-incubation with husband's sperm in the IUI. Primary outcome: To compare the incidence of clinical pregnancy outcome in those infertility patients undergoing IUI with female PRP co-incubation with husband's sperm group and non-PRP group. Secondary outcomes: * To evaluate the safeness between the female PRP co-incubation with husband's sperm in the IUI group and non-PRP group, including potential infection rate or other complications such as ectopic pregnancy and molar pregnancy * To evaluate the sperm quality between the intervention group and control group Data analysis: Data analysis will be performed using Statistical Packages of Social Sciences for Windows Expected results: The investigators expect that a 50% pregnancy rate increase after the application of female PRP co-incubation with husband's sperm in the IUI

Outcome measures Primary outcome: To measure the rate of clinical pregnancy outcome in subjects undergoing IUI with PRP co-incubation with husband's sperm group than non-PRP group. Clinical pregnancy rate as determined by a positive serum beta-hCG test result at 6 weeks gestation and ultrasound scanning will be performed to confirm at least one gestational sac around 2 to 3 months after IUI. Secondary outcomes: * To evaluate the rate of potential infection or other complications such as ectopic pregnancy and molar pregnancy in the intervention group and control group * Assessment of sperm quality Sperm quality will be assessed before raw semen, post isolated processed semen and after female PRP co-incubation with the processed semen Sample size IUI's average clinical pregnancy rate is 10.1% in the past five years at Assisted Reproductive Technology Unit of the department of Obstetrics and Gynecological in the Prince of Wales Hospital, we assume a 50% pregnancy rate increase after the application of female PRP co-incubation with husband's sperm in the IUI, the pregnancy rate is expected to be 15.15% in the sample size estimation. With power calculations (G\*Power3.1.9.7; t tests-Means: difference of two independent means), 64 couples (128 patients) in each arm would provide a two-sided 80% power with an alpha of 0.05. We aim to recruit a total of 144 couples (288 patients), that is 72 couples (144 patients) in each arm, to account for a 10% dropout rate. Subjects undergoing IUI will be included in the study if they fulfilled the inclusion criteria. The consented subjects will be randomized into two groups via simple random sampling. The subjects' names will be drawn randomly from a pool in which each had an equal probability of being chosen. * Intervention group (Female PRP co-incubation with husband's sperm in the IUI) * Control group (non-PRP in the conventional IUI) Data processing and analysis The researchers will ensure the confidentiality of sensitive data by minimizing the number of personnel who handles subject data. The computer data will be encrypted as required to maximize security. All paper documents will be locked in filing cabinets, and only authorized personnel could access this information. Data will be stored for up to 10 years. Statistical analysis will be performed using the SPSS (SPSS Inc. Chicago, IL, USA). Data will be presented by percentage, mean and standard deviation, and median where appropriate. Chi-square test, Fisher's exact test, student-t test will be used for data analysis where appropriate. A two-tailed probability value of p\< 0.05 will be considered statistically significant.
