Chinese women (n = 1950) of relatively young age, with normal range of basal FSH and antral follicle count undergoing an in vitro fertilisation cycle were selected and testosterone and dehydroepiandrosterone sulfate levels were measured on Day 3 of the menstrual cycle before subsequent in vitro fertilisation treatment. The main outcome measures of the study were ovarian stimulation parameters and clinical pregnancy. Basal testosterone levels of poor responders and non-pregnant women were significantly lower than normal responders and pregnant women, respectively. Patients with low basal testosterone levels had significantly lower number of mature oocytes, cleavage-stage embryos, frozen embryos, lower fertilisation and pregnancy rates and required higher doses of gonadotrophins. Androgen levels had no correlation with early spontaneous abortion rates. Multivariable logistic analysis revealed that low basal testosterone (&amp;lt;0.88 nmol L\u20131) was an independent risk factor for poor oocyte yield (odds ratio: 1.61; 95% confidence interval: 1.01\u20132.57; P = 0.045). In conclusion, a low level of basal testosterone was a significant risk factor for poor oocyte yield after ovarian stimulation and might negatively influence pregnancy chances with in vitro fertilisation. Basal dehydroepiandrosterone sulfate levels were not predictive for poor ovarian response or negative pregnancy outcome in this population.<\/jats:p>","DOI":"10.1071\/rd14061","type":"journal-article","created":{"date-parts":[[2014,7,14]],"date-time":"2014-07-14T20:13:59Z","timestamp":1405368839000},"page":"286-292","source":"Crossref","is-referenced-by-count":1,"title":["Low level of basal testosterone: a significant risk factor for poor oocyte yield after ovulation induction"],"prefix":"10.1071","volume":"28","author":[{"given":"Jing","family":"Guo","sequence":"first","affiliation":[{"name":"ADepartment of Obstetrics and Gynaecology, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, 107 Yanjiang Road, Guangzhou 510120, Guangdong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingxue","family":"Zhang","sequence":"additional","affiliation":[{"name":"ADepartment of Obstetrics and Gynaecology, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, 107 Yanjiang Road, Guangzhou 510120, Guangdong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Li","sequence":"additional","affiliation":[{"name":"ADepartment of Obstetrics and Gynaecology, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, 107 Yanjiang Road, Guangzhou 510120, Guangdong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjun","family":"Wang","sequence":"additional","affiliation":[{"name":"ADepartment of Obstetrics and Gynaecology, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, 107 Yanjiang Road, Guangzhou 510120, Guangdong, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongzi","family":"Yang","sequence":"additional","affiliation":[{"name":"ADepartment of Obstetrics and Gynaecology, Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University, 107 Yanjiang Road, Guangzhou 510120, Guangdong, China."},{"name":"BCorresponding author.
