Gender differences in factors associated with depression in infertility patients.

AIMS: To clarify gender differences in the demographic variables and infertility problems associated with depression among men and women undergoing infertility treatment. DESIGN: A cross-sectional study. METHODS: We surveyed 380 women and 360 men undergoing infertility treatment at the reproductive medicine center of a hospital in China's Ningxia Province from March - September 2016. RESULTS: For women, ethnicity, the number of clinic visits, social concern, and sexual concern were factors linked with depression symptoms. For men, treatment cost pressure and social concern were significantly associated with depression symptoms. CONCLUSION: Psychological counseling and intervention programs should be integrated into in-vitro fertilization treatments and interventions should be targeted based on gender differences. IMPACT: The provision of treatment-related sexual knowledge by nurses is indispensable for infertile participants. Mental health policies should be developed to facilitate the implementation of psychological services. Psychological counseling and intervention programs should be integrated into in vitro fertilization treatment to help men and women with infertility cope with psychological distress.

[Relationship between ERCC2 single nucleotide polymorphisms and male idiopathic infertility in Ningxia].

OBJECTIVE: To explore the influence of the DNA repair gene ERCC2 single nucleotide polymorphisms (SNPs) rs13181, rs1618536, and rs1799793 on male idiopathic infertility in Ningxia, China. METHODS: Using MassArray, we conducted a case-control study and genotyped three ERCC2 SNPs rs13181, rs1618536, and rs1799793 for 351 males (aged 31.0 +/- 4.2 years) with idiopathic infertility and another 327 normal fertile men (aged 33.0 +/- 5.9 years) as controls. RESULTS: The ERCC2 AnyG-anyA-anyA genotypes were significantly associated with an increased risk of idiopathic infertility (OR 0.414, 95% CI 0.176 - 0.970), while the three single ERCC2 SNPs rs13181, rs1618536, and rs1799793 showed no significant differences between the cases and controls (P > 0.05). CONCLUSION: The ERCC2 SNPs rs13181, rs1618536, and rs1799793 play a role of interaction in male idiopathic infertility in Ningxia, contributing to the risk of the disease.

[Digit length ratio and male fertility among infertile patients in Ningxia].

OBJECTIVE: To investigate the association between the digit length ratio (DLR) and male fertility in Ningxia. METHODS: Using an electronic sliding caliper, we measured the lengths of the index finger (D2), middle finger (D3), ring finger (D4) and little finger (D5) of both the right and left hand of 136 infertile males in Ningxia, 45 of them with normal and the other 91 with abnormal semen, including 28 cases of oligozoospermia, 10 cases of obstructive azoospermia (OA) and 53 cases of nonobstructive azoospermia (NOA). We calculated the DLRs of D2:D3, D2:D4, D2:D5, D3:D4, D3:D5 and D4:D5 and compared them among different groups. RESULTS: The mean values of FLR presented a pattern of D2:D3 < D2:D4 < D3:D4 < D2:D5 < D4:D5 in the infertile males. DLRs of D2:D3, D2:D4, D2:D5, D3:D5 and D4:D5 of the right hand were significantly higher in the abnormal than in the normal semen group (t = 2.56, 2.48, 3.57, 2.85, 2.53; P < 0.05); those of D2:D3, D2:D4, D2:D5 and D4:D5 of the right hand presented a pattern of NOA > oligozoospermia > OA > normal semen group, while that of D3:D5 presented a pattern of NOA > OA > oligozoospermia > normal semen group. The NOA group showed a significantly higher DLR of the right hand than the normal semen group in D2:D3, D2:D4, D3:D5 and D4:D5, the oligozoospermia group in D2:D4, D3:D5 and D4:D5, and the OA group in D2:D3 (P < 0.05). The D4:D5 DLR of the right hand was remarkably higher in the Han than in the Hui ethnic group (t = 2.01, P < 0.05). CONCLUSION: Higher DLRs of D2:D3, D2:D4, D2:D5, D3:D5 and D4:D5 of the right hand were associated with lower fertility in infertile males in Ningxia. And the D4:D5 FLRs of the right hand may be different between Hui and Han infertile men in Ningxia.
