The effect of paternal age on intracytoplasmic sperm injection outcome in unexplained infertility
Arab Journal of Urology
Objective: : To examine the effect of paternal age on intracytoplasmic sperm injection (ICSI) outcomes in unexplained infertility Subjects and Methods: : This retrospective study, done at the Hamad Medical Corporation, Doha, Qatar screened infertile couples who underwent ICSI between 2014 and 2019 for the inclusion and exclusion criteria defining 'unexplained infertility'. Couples recruited were allocated into two groups: Group A (paternal age <35 years) and Group B (paternal age ≥35 years). Baseline characteristics, investigations including semen and advanced sperm function tests and ICSI records were compared for primary outcomes such as fertilisation, cleavage, clinical pregnancy, miscarriage and live birth; and secondary outcomes such as semen parameters and advanced sperm functions (DNA fragmentation index and oxidation reduction potential). Results: : We found that final pregnancy outcomes including clinical pregnancy rate (P = 0.231), live-birth rate (P = 0.143), and miscarriage rates (P = 0.466) were not significantly different between the two age groups. Normal fertilisation (P = 0.01) and cleavage rate after ICSI (P = 0.001) were statistically significant when the age groups were compared. Also, normal sperm morphology was found to be significantly different (P = 0.041). Conclusions: : Advanced paternal age affects sperm morphology, fertilisation and embryo cleavage in ICSI but does not appear to affect clinical pregnancy, miscarriage or live-birth rates. ICSI appears to be a valid fertility treatment option in advancing paternal age.
The Effect of Paternal Age on Icsi Outcome in Unexplained Infertility
Fertility and Sterility
despite normal fertilization and normal embryo development. Unfortunately, for unknown reasons, this simple inexpensive test is not performed in most fertility centers when evaluating the male's semen analysis. The purpose of the present study was to evaluate whether the association of an additional abnormal semen parameter, i.e., either low motile density, low normal morphology by strict criteria, or low % motility, negatively effected the live delivered pregnancy rate in males with low HOS test scores with IVF with ICSI. DESIGN: Prospective observational comparative study. MATERIALS AND METHODS: The male partners of couples seeking help for infertility had semen analyses performed for standard parameters and also for the HOS test. If the HOS test score was <50% the couples were explained that successful live deliveries with this abnormality is extremely rare without treatment. The two treatment options were either IVF with ICSI or performing intrauterine insemination (IUI), but with this toxic protein causing the implantation defect, the sperm would first be treated with the protein digestive enzyme chymotrypsin. The first IVF cycle of those choosing IVF with ICSI was evaluated. The data were sub-analyzed into 3 sets of pairs-low motile density vs. normal (<10x10 6 /mL vs. >10x10 6 / mL), subnormal morphology vs. normal by strict criteria (<4% vs. >5%) and low percent motility vs. normal (<30% vs. >30%). RESULTS: The results are seen in the table below.

Maternal age of 35 years or over is a well-known risk factor for human reproduction that has been extensively investigated by demographers and epidemiologists. However, the possibility of a paternal age effect has rarely been considered. We carried out review of the literature to investigate the effect of paternal age on the risks of infecundity and miscarriage. We carried out a MEDLINE search and checked the exhaustiveness of our reference list. We identified 19 articles analysing the effect of paternal age. Epidemiological studies provided evidence that paternal age older than 35-40 years affects infecundity. However, the few studies based on data from assisted reproductive techniques (especially IVF with ovum donation) do not confirm this finding. All studies analysing the effect of paternal age on the risk of miscarriage showed an increased risk in men aged 35-40 years or over. Other studies have shown some evidence for a paternal age effect on late foetal deaths. The risks of i...
Sperm DNA fragmentation and male age: results of in vitro fertilization treatments
JBRA Assisted Reproduction
Objective: This study aimed to assess the effects of sperm DNA fragmentation in parents belonging to different age groups. The couples included in the study comprised normozoospermic men and infertile women undergoing conventional IVF. Methods: The results obtained from 163 conventional IVF cycles were analyzed retrospectively. The couples enrolled in the study included women aged between 30 and 37 years. Sperm DNA fragmentation was studied using the TUNEL assay. The patients were split into four groups based on male age and sperm DNA fragmentation, as follows: Group 1: ≤39 years and TUNEL assay ≤20%; Group 2: ≤39 years and TUNEL assay >20%; Group 3: ≥40 years and TUNEL assay ≤20%; and Group 4: ≥40 years and TUNEL assay >20%. Results: No significant differences were found in semen parameters or fertilization rates between groups. Groups with <20% sperm DNA fragmentation showed significant differences in other parameters, including higher blastocyst formation rate (Group 1: 63% and Group 3: 60% vs. Group 2: 43% and Group 4: 41%, p<0.05) and higher expanded blastocyst formation rate (Group 1: 42% and Group 3: 40% vs. Group 2: 21% and Group 4: 18%, p<0.05). Miscarriage rate was significantly higher in Group 4 (42% and 46% vs. 5%, 25% and 5% in Groups 1, 2 and 3, respectively, p<0.05). Conclusions: Our results showed lower blastocyst formation rates from IVF when males had high levels of sperm DNA fragmentation. Higher miscarriage rates were also observed in couples with males aged 40+ years. These results reinforce the need to inform couples with male partners aged 40+ years about the potential risks inherent to fertility treatment.
Intracytoplasmic sperm injection and advanced maternal age: Success or treatment failure?
Pakistan journal of pharmaceutical sciences, 2019
Infertility rate documented in Pakistan is 21.9% with only 25% success rate even after procedures like intracytoplasmic sperm injection (ICSI). This rate is further on the decline with enhancement of female age. We aimed to observe the effect of female age on oocyte parameters and reproductive outcome after ICSI. It was done by retrospective analysis of a quasi- experimental design carried out after approval from "Ethical review board of Islamabad clinic serving infertile couples" from July 2010 to August 2011. The response to ovarian stimulation in (282) females was assessed on the basis of groups, A, B, C and D with age ranges up to 25years; 25.1 to 30years; 30.1 to 35years and >35years, respectively. The outcome was assessed as non-pregnant, preclinical abortion and clinical pregnancy groups on the basis of beta hCG and cardiac activity by trans-vaginal scan. We observed that maximum number of pregnancies 32 (38%) occurred in C group, and least 10 (10%) in group A. T...
The effect of paternal age on assisted reproduction outcome
Fertility and Sterility, 2011
Objective: To summarize the current knowledge about the association between paternal age and assisted reproductive technology (ART) outcomes. In contrast to the extensive investigation of the relationship between maternal age and the success of ART, there are few studies examining the effect of paternal age on ART outcomes. Design: Systematic review of the literature. By means of a PubMed literature search using the phrases ''paternal age'', ''male age'', and ''assisted reproductive technology'', we identified articles that investigated the role of male age in in vitro reproduction techniques.

We report on 332 infertile couples who underwent 1115 cycles of intrauterine insemination (IUI) with washed husband's semen. The indication for IUI was an abnormal post-coital test due to either a male or cervical infertility factor. The mean number of IUI cycles per patient was 3.4, the overall pregnancy rate 18.7%, and the pregnancy rate per cycle 5.6%. The cumulative pregnancy rate calculated by life table analysis showed that 16.0% of pregnancies occurred in the first three treatment cycles, while the cumulative pregnancy rate was 26.9% by the sixth cycle. The outcome of the therapy was adversely affected if the woman's age was >39 years and/or total motile sperm count per insemination was <1X1O*. No pregnancy occurred in women older than 44 years or in cases with a total motile sperm count before semen preparation of <1X1O*.
