In order to explore the effect of neonatal androgen administration on oocyte quality, ovulation induction and in vitro fertilization (IVF) were performed in androgen-sterilized mice. Androgen sterilized mice were produced by the subcutaneous injection of testosterone propionate (TP) at 5 days of age and ovulation induction was performed by pregnant mare's serum gonadotropin (PMSG)-human chorionic gonadotropin (hCG) treatment at 9 to 13 weeks old. The number of oocytes ovulated in TP-injected mice was 19.9 +/- 2.0 (Mean +/- SE) and was significantly less than that in normal mice (37.8 +/- 1.9; P < 0.01). The fertilization rate of oocytes retrieved from TP-treated mice (38.8%) was significantly lower than that from normal mice (60.3%; P < 0.01). These results indicate that neonatal androgen treatment has a detrimental effect on oocyte maturity.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D008811	Mice, Inbred DBA	An inbred strain of mouse. Specific substrains are used in a variety of areas of BIOMEDICAL RESEARCH such as DBA/1J, which is used as a model for RHEUMATOID ARTHRITIS.

D009865	Oocytes	Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM).	Ovocytes,Oocyte,Ovocyte

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013245	Sterilization, Reproductive	Procedures to block or remove all or part of the genital tract for the purpose of rendering individuals sterile, incapable of reproduction. Surgical sterilization procedures are the most commonly used. There are also sterilization procedures involving chemical or physical means.
