PRP Improves Blastocyst Formation in ICSI Cycles

The goal of this clinical trial is to learn if platelet rich plasma (PRP) works to improve embryo development rates and embryo quality in IVF cycles, involving male adult patients with severe sperm disorders. The main questions it aims to answer are: * Does PRP improve sperm quality of male adult patients undergoing IVF? * Does PRP improve embryo development and embryo quality of the IVF patients? Researchers will compare embryos from IVF patients treated with PRP to those not treated with PRP to see if PRP improves embryo development and embryo quality. Participants will: * Provide semen sample for IVF * Provide blood sample for PRP preparation * Have PRP obtained from their blood added to their sperm sample

The Impact of Probiotics on Sperm Quality in Middle-aged Men

The clinical trial aims to investigate the impact of probiotic strain BL21 on sperm quality among 46 middle-aged male participants. The primary objective is to validate whether probiotic strain BL21 can effectively improve sperm quality among middle-aged male participants. Initially, participants were instructed to consume the recommended amount of probiotic powder for approximately 8 weeks. At baseline, week 4, and week 8 endpoints, semen analysis, hormone level testing, serum cytokine testing were conducted on the participants, and stool samples were collected from them.

Obesity With Sperm Quality in Men With Fertility Need

This study aims to investigate the impact of different types of obesity on sperm quality. Participants will be divided into three groups: a normal BMI group, an obese group without pudendal fat wrapping the testicles, and an obese group with pudendal fat wrapping the testicles. Sperm quality parameters will be compared among these groups to assess potential differences associated with different types of obesity.
