Intrauterine insemination with donor sperm (IUI-D) is an assisted reproductive technology (ART) offered to couples with definitive male infertility or risk of genetic disease transmission. Here, we sought to evaluate our practice in IUI-D and identify factors that influenced the success rate. We performed a retrospective, single-center study of all IUI-D procedures performed at Lille University Medical Center (Lille, France) between January 1, 2007, and December 31, 2017. Single and multivariate analyses with a mixed logistic model were used to identify factors associated with clinical pregnancies and live births. We included 322 couples and 1179 IUI-D procedures. The clinical pregnancy rate was 23.5%, and the live birth rate was 18.9% per IUI-D. In a multivariate analysis, the women's age was negatively associated with the live birth rate. The number of motile spermatozoa inseminated was the only factor associated with both clinical pregnancies and live births, with a chosen threshold of 0.75 million. The clinical pregnancy and live birth rates were, respectively, 17.3% and 13.0% below the number of motile spermatozoa inseminated threshold and 25.9% and 21.0% at or above the threshold (all P = 0.005). The number of motile spermatozoa inseminated was the only factor that significantly influenced both pregnancies and live-birth rates after IUI-D. Indeed, below a threshold of 0.75 million motile spermatozoa inseminated, those rates were significantly lower. Application of this number of motile spermatozoa inseminated threshold may help centers to allocate donations more effectively while maintaining reasonable waiting times for patients.

Objective:
To analyze the correlation of the sperm DNA fragmentation index (DFI) level with semen parameters and pregnancy outcomes of artificial insemination of the husband (AIH) in the cycle of intrauterine insemination (IUI).
METHODS:
We collected the clinical data on 777 cases of IUI, including female clinical indicators, male semen parameters, sperm DFI and pregnancy outcomes. According to the DFI level, we divided the patients into three groups: DFI < 15%, 15% ≤ DFI < 30% and DFI ≥ 30%.
RESULTS:
The sperm DFI level was significantly elevated with the increased age of the males (P = 0.002) and closely related to the total number of motile sperm (P = 0.002) and total sperm motility (P = 0.000) before treatment, as well as to sperm concentration (P = 0.000), total sperm motility (P = 0.001) and total number of progressively motile sperm (P = 0.000) after density gradient centrifugation. The rate of clinical pregnancy was decreased in the DFI ≥ 30% group. There were no statistically significant differences between sperm DFI and the rates of clinical pregnancy and abortion.
CONCLUSIONS
Male age significantly affects the sperm DFI level. Sperm DFI is closely related to sperm motility and total number of progressively motile sperm, but not to the rates of clinical pregnancy and abortion in patients undergoing IUI. IUI can be used as an effective method of assisted reproduction for male infertility./.

PURPOSE: To investigate the associations between sperm DNA fragmentation (SDF) and embryo formation rate in normal responder women to in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). MATERIALS AND METHODS: Fifty-three consecutive, fresh IVF/ICSI cycles performed from 2014 to 2017 were selected. All women were normal responders (4 to 14 mature oocytes were retrieved) and at least one normally fertilized oocyte with two pronuclei was obtained in all cycles. Semen was collected on the day of oocyte retrieval, and SDF levels were measured by sperm chromatin dispersion test (Halosperm assay). At day 3 after insemination, embryo quality was evaluated by morphologic criteria and categorized as A/B/C/D. Top quality embryo were defined as grade A embryos with seven cells or more. RESULTS: SDF levels showed a positive linear correlation with the male's age (r=0.307, p=0.025) and a negative linear correlation with sperm motility (r=−0.491, p<0.0001). To achieve top-quality or a grade A embryo formation rate >70%, the cut-off value SDF was <30.7% for each. Among individuals with SDF <30.7%, the median top-quality or grade A embryo formation rate was significantly higher than that among individuals with SDF ≥30.7% (38.1% vs. 20.0%, p=0.038; 50% vs. 25.0%, p=0.017). CONCLUSION: In normal responder women, high SDF level resulted in low day 3 embryo formation rates. Our results suggest a paternal effect on embryo quality in IVF/ICSI cycles.

OBJECTIVE: The primary objective of this study was to compare clinical pregnancy rates in intrauterine insemination (IUI) treatment cycles with transabdominal ultrasound guidance during intrauterine catheter insemination (US-IUI) versus the “blind method” IUI without ultrasound guidance (BM-IUI). The secondary objective was to compare whether US-IUI had better patient tolerability and whether US-IUI made the insemination procedure easier for the clinician to perform compared to BM-IUI. METHODS: This was a randomized controlled trial done at the Reproductive Medicine Unit of General Hospital Kuala Lumpur, Malaysia. We included women aged between 25 and 40 years who underwent an IUI treatment cycle with follicle-stimulating hormone injections for controlled ovarian stimulation. RESULTS: A total of 130 patients were recruited for our study. The US-IUI group had 70 patients and the BM-IUI group had 60 patients. The clinical pregnancy rate was 10% in both groups (p> 0.995) and there were no significant difference between the groups for patient tolerability assessed by scores on a pain visual analog scale (p= 0.175) or level of difficulty for the clinician (p> 0.995). The multivariate analysis further showed no significant increase in the clinical pregnancy rate (adjusted odds ratio, 1.07; 95% confidence interval, 0.85–1.34; p= 0.558) in the US-IUI group compared to the BM-IUI group even after adjusting for potential covariates. CONCLUSION: The conventional blind method for intrauterine catheter insemination is recommended for patients undergoing IUI treatment. The use of ultrasound during the insemination procedure increased the need for trained personnel to perform ultrasonography and increased the cost, but added no extra benefits for patients or clinicians.

We determined the threshold proportion of polymorphonuclear leukocytes (PMNs) for a diagnosis of cytological endometritis (CEM), the risk factors for this condition, and its impact on reproductive performance in dairy cows. Uterine cytology was performed on 407 Holstein cows 4 weeks postpartum to determine the proportions of endometrial cells and PMNs. A receiver operator characteristics curve was used to determine the threshold above which the PMN proportion affected the likelihood of cows conceiving by 200 days postpartum. The optimal threshold was ≥ 14% PMN (sensitivity, 31.3%; specificity, 81.7%; p < 0.05). The farm identity, retained placenta (odds ratio [OR] = 1.87), and septicemic metritis (OR = 3.07) were risk factors for CEM (p < 0.05). Cows with CEM were less likely to resume cyclicity (OR = 0.58) and to conceive by 200 days postpartum (hazard ratio = 0.58). Cows with CEM tended (p < 0.1) to be less likely to become pregnant after their first insemination (OR = 0.65) and to require a greater number of inseminations per conception (2.3 vs. 2.2). In conclusion, a PMN threshold of 14% defined the presence of CEM at 4 weeks postpartum. The farm, retained placenta, and septicemic metritis were risk factors for CEM, which reduces subsequent reproductive performance.

7.Reasons of shortage for donated sperm and plan to resolve deficiencies in the sperm donor system
Journal of the Korean Medical Association 2018;61(7):408-415
Sperm banking from recruited donors is an important way to help infertile couples who want to achieve pregnancy by therapeutic artificial insemination, even in the era of in vitro fertilization. Korea has the lowest population density of newborns among all Organization for Economic Co-operation and Development countries, with a total fertility rate of 1.17 and an annual birth rate of 300,000 or less as of 2017. This situation emerged due to various causes, including late marriage, fecundity problems, and air pollution. Nevertheless, we have imposed strict limits on basic research and clinical activities, including the operation of sperm banks, in the field of human reproduction under the 2005 Bioethics and Safety Act. Therefore, cryopreserved sperm for artificial insemination is almost absent in the sperm banks of major human reproduction centers. To resolve this difficult situation, as well as to increase the operation of sperm banks in Korea to the global standard level, the author evaluates the underlying reasons for donor sperm use by azoospermic patients from medical, ethical, legal, religious, and cultural perspectives, and then proposes a plan to resolve this situation including highly regulated standard operating procedures to ensure comprehensive safety practices for voluntary sperm donors and infertile couples, as well as to build an ideal sperm donation program.

8.Penal provisions of Bioethics Law: problems and improvements
Journal of the Korean Medical Association 2018;61(7):392-402
Chapter 9 of the Bioethics Law has several problems due to strict research standards and strong penalties. Therefore, biomedical researchers in Korea have raised several objections to this Law. To make matters worse, the normative power of the Law is significantly diminished because norms and penalties are divergent. Articles 2, 24, 26, 27, 28, and 32 of the Law require amendment because the current regulations on sperm retrieval, sperm management, and sperm use are insufficient. At a minimum, legislation for artificial insemination and in vitro fertilization should be consolidated. It is also necessary for sperm researchers and donors to be notified of their rights and duties. Section 9 of the Bioethics Law should therefore be amended. In particular, its legal formulation should be modified in order to enhance the effectiveness of bioethics law. This is in accord with the spirit of the Constitution. The principle of proportionality should be maintained. The statutory form should be revised to the level of abortion. Not only are the actors in embryo research diverse, including medical personnel, medical institutions, donors, veterans, and mediators, but embryo research involves multiple behavioral aspects, including intentional acts and negligence (violation of state duty). Excessively free-form activity is prescribed. Although the value of life is important, heavy punishment violates human dignity and human values. This legislation should not reflect to be grounded in emotional reactions such as anger.

9.Comparative analysis of medical, legal, and ethical considerations for establishing a standard operating protocol for artificial insemination by donor
Journal of the Korean Medical Association 2018;61(7):383-391
Artificial insemination by donor is an important means of improving the likelihood of pregnancy in couples affected by male factor infertility, but it poses medical, legal, and ethical issues due to the involvement of third parties, such as the sperm donor. In Korea, the Bioethics and Safety Act was enacted for the purpose of preventing and eliminating unethical research on germ cells, and such research was limited to matters related to the use of assisted reproductive technologies, centering on embryos, oocytes, and protecting the health of oocyte donors. However, this law is incomplete in terms of specific standards or regulations relating to the donation and receipt of sperm. In Korea, artificial insemination by donor has been carried out without a standard operating protocol for donation and receipt of sperm, which would include testing sperm donors for diseases, limiting the number of donor offspring, compensation for donations, and the role of anonymity and non-anonymity. The diversity of policies worldwide shows that each country has its unique set of guidelines tailored for its own specific needs and practical considerations. Herein, I present a standard operating protocol of medical, legal, and ethical principles for artificial insemination by donor that is suitable for domestic circumstances, along with a comparison of recommendations and guidelines of other countries concerning sperm donation issues.

OBJECTIVE: The aim of this study was to measure reactive oxygen species (ROS) production and total antioxidant capacity (TAC) in the seminal fluid of the male partners in couples undergoing intrauterine insemination and to evaluate correlations between these values and their semen parameters. METHODS: The study was conducted at Vamsam Fertility Center, Coimbatore, India and enrolled 110 male patients from whom semen samples were collected. ROS production was measured by a thiobarbituric acid reactive species assay, and TAC was measured by a 2,2-diphenyl-2-picrylhydrazyl free radical assay. The differences in the TAC and malondialdehyde (MDA) levels between the subfertile and fertile groups were analysed. Correlations between sperm parameters and TAC and MDA levels were statistically analysed, and cutoff values with respect to the controls were determined. All hypothesis tests used were two-tailed, with statistical significance assessed at the level of p < 0.05. RESULTS: A total of 87 subfertile and 23 fertile men were included in the study. The mean MDA level was significantly higher in the subfertile subjects than in the fertile subjects, and the mean antioxidant level was significantly lower in the subfertile subjects than in the fertile subjects. Seminal MDA levels were negatively associated with sperm concentration, motility, and morphology, whereas the opposite was seen with TAC levels. CONCLUSION: Measurements of seminal TAC and ROS are valuable for predicting semen quality, and hence predicting the outcomes of fertility treatment.
