ABSTRACT

Background: Seasonal variations in semen parameters have been detected in many previous studies, mostly conducted in the West and Mediterranean countries. Located in a tropical region, we have only three seasons - summer, winter and rainy season. Literature search did not reveal studies from Indian subcontinent. Aims: Our objective was to find if our climate produced seasonal variations in semen parameters such as sperm concentration (SC), total motile SC, morphology and vitality, which may have implications in fertility management. Settings and Design: This is a descriptive study, conducted at a tertiary level hospital. Semen analysis reports of male partners of all infertile couples during the 4-year period from 2019 to 2022 were analysed. Materials Methods: The data were collected from records of all infertile couples registered for the treatment in the department during the study period. Semen analysis reports of male partners of all infertile couples attending outpatient department of the Reproductive Medicine Department during the 4-year period from January 2019 to December 2022 were collected. The data of azoospermic and severe oligospermic (<5 million/mL) men and those receiving hormone treatment were excluded. Statistical Analysis Used: Data were analysed using SPSS 23 and variables expressed as mean and standard deviation. Changes in mean values over years and over seasons were evaluated using F-test. Post hoc analysis was done using Sidak method. P < 5% was considered statistically significant. Results: The data of 2326 patients were analysed. SC was lowest during summer but was not statistically significant. Sluggishly motile sperm per cent was maximum in rainy season (P = 0.002). Post hoc analysis showed significant variations in summer samples compared to both rainy and winter seasons. Head defect (HD) and tail defects showed a significant seasonal variation (P = 0.011 and P = 0.024, respectively), lowest HD seen in rainy season. Conclusion: Semen parameters showed seasonal variations, with favourable features in colder climates, and may need to be considered in infertility management, especially if the male is oligospermic.

ABSTRACT

BACKGROUND: 46 XX male syndrome, a rare case of infertility was first reported by de la Chapelle in 1964. In newborn males, the incidence rate of the syndrome varies from 1/9000 to 1/20000. Here, a case of 46 XX male syndrome is reported with clinical, biochemical and genetic changes of the patient and normal masculine features. CASE PRESENTATION: A 29 year old male with infertility registered at the Sree Avittom Thirunal Hospital of Government Medical College, Thiruvananthapuram for fertility treatment. He was diagnosed with non obstructive azoospermia in repeated semen analysis. Chromosomal analysis on peripheral blood lymphocytes has revealed 46 XX male syndrome and the result was confirmed with Fluorescent In situ Hybridization (FISH). Real time polymerase chain reaction failed to detect genes on azoospermia factor regions, AZFa, AZFb and AZFc of Y chromosome, but detected SRY gene positivity. Masculine features of patient were normal except small sized testis, ejaculatory dysfunction and azoospermia. CONCLUSION: Appearance of the external genitalia will be generally normal in 46 XX with SRY positive males and generally difficult to identify before puberty because there will not be any significant clinical indication. The present case report demonstrates that mere physical or clinical examination may not disclose the genetic defects. Therefore, in addition to general examination, it is essential to perform genetic analysis on men with infertility.
