Infertility is the inability of a sexually active non-contraceptive couple to achieve pregnancy in one year. Sperm motility is one of the most important prerequisites to achieving fertilization and pregnancy . The objective of the current study was to improve certain sperm function parameters following in vitro activation of men suffering from asthenozoospermia by using a novel combination of motility stimulant substances, namely Maca, L-carnitine, and Pentoxifylline, to be used for assisted reproductive technologies programs in the future.Ninety asthenozoospermic patients were involved in the current study. Each sample was divided into two equal portions. One part was considered as a control by using Ham’s F12 medium, and the other part was considered as a treated group by adding medium content, a mixed combination of Maca powder extracts (Lepidium meyenii) (M)1mg/ml, Pentoxifylline (PTX) 10 mg /ml, and L-Carnitine (LC) 0.5mg /. Certain sperm function parameters were examined before and following in vitro preparation using the swim-up technique according to WHO guidelines.The results showed a significant (p<0.001) elevation in active sperm motility grade A, B, and progressive motility following in vitro preparation by Ham’s F12 media and mixed culture medium compared to before activation. The morphologically normal sperm percentage was significantly higher in mixed culture medium compared to control medium, and before activationWhile the results of DNA normality by using mixed culture and Ham’s F12 media were statistically shown a significant (p<0.001) reduction compared with before activation . It is concluded that the combination medium have a superior effects on certain sperm function parameters and DNA normality enhance its usage in sperm activation by swim up technique for ART programs.
To assess the predictive value of different clinical, laboratory, and ultrasound parameters in Letrozole when used as an ovulation induction in anovulatory infertile PCOS women. The current study was done in the secondary-referral infertility clinic in AL-Yarmouk teaching hospital, and Al-Mustansiriyah medical college. Sixty-seven anovulatory infertile women with the polycystic ovarian syndrome. Letrozole was given orally on day 2 or 3 of the menstrual cycle for five days and repeated for three consecutive cycles. The primary outcome measures were to evaluate the response rate in the form of successful ovulation and clinical pregnancy. The ovulation rate was (64.2%), with clomiphene naïve vs. previous clomiphene use; it was 87.5%, 51.2% respectively, while pregnancy rate was (32.8%), 41.6% with clomiphene naïve vs. 27.9% with previous clomiphene use. Clinical (age, BMI, Waist circumference, cycle length and days between cycle, infertility period and type, previous reproductive outcome, androgen symptom and m-FG score), laboratory (E 2 , FSH, LH, testosterone, FAI, FBS, fasting insulin, HOMA – IR, and AMH) and ultrasound (mean ovarian volume, mean AFC and antral follicular diameter) parameters were founded to affect ovulation and pregnancy in different extent. After putting all variables in a scoring system, it was found that if the patients had > 26 points for the score, it's more likely that the woman becomes pregnant. A predictive pregnancy score was developed from basic clinical, laboratory, and ultrasound parameters. It may help the clinician to individualized ovulation induction protocol in PCOS women; however, external validation of this system is recommended in a more extensive prospective study.
Background: The effect of L-carnitine (LC) on the male infertility have been previously reviewed. However there are few studies about the effect of LC on sperm function parameters in vitro. Objectives: The objective of this study was to improve certain sperm function parameters in vitro of asthenozoospermic infertile men using LC as a motility stimulant substance which may enhance the medium used for assisted reproductive technologies (such as artificial insemination) in future. Methods: Semen was collected from 50 infertile men involved in the current study. Each semen sample was divided into two portions. One part was considered as a control and in vitro activated by using culture medium only. The other portion was considered as treated group and in vitro activated by adding LC (0.5mg) to the culture media. Certain sperm function parameters were examined before and following in vitro activation using simple layer technique. Results: The results revealed highly significant increment (P<0.01) in the percentage of total sperm motility grades (A+B+C) and progressive sperm motility grade (A) with a significant improvement (P<0.05) in the percentage of progressive sperm motility grade (B) and morphologically normal sperm when using LC medium in comparison with control medium after 30 minutes incubation. Conclusion: It is concluded from the results of the present study that adding 20% LC to the culture medium ofthe in vitro sperm activation leads to an improvement in certain spermfunction parameters.
