This category covers the structure and function of the female reproductive system, including the development of oocytes, the menstrual cycle, and the hormonal regulation of reproductive processes.
Endometriosis is the condition in which endometrial tissue is found outside the uterus, often causing pelvic pain and infertility.

Embryonic genome activation typically begins during the blastocyst stage when the embryo starts transcribing its own genes.

hCG is administered to mimic the natural LH surge, inducing final oocyte maturation before retrieval in IVF procedures.

Secondary spermatocytes undergo meiosis II to form spermatids, which later mature into spermatozoa.

The endometrium is the innermost layer of the uterus that undergoes cyclical regeneration and shedding during menstruation.
Ref: NCERT Class 12 Biology Chapter 2: Human Reproduction Female Reproductive System and Gametogenesis
The endometrium, or the inner lining of the uterus, is shed during menstruation if no implantation occurs.

Azoospermia is defined as the complete absence of sperm in the ejaculate, a major cause of male infertility.

PCOS is marked by the presence of multiple cysts on the ovaries, irregular cycles, and elevated androgen levels.

ZIFT involves fertilization in vitro and the transfer of the resulting zygote into the fallopian tube.
Ref: NCERT Class 12 Biology Chapter 2: Human Reproduction Female Reproductive System and Gametogenesis
Fertilization usually takes place in the fallopian tube, where the sperm meets the ovum.
Ref: NCERT Class 12 Biology Chapter 2: Human Reproduction Female Reproductive System and Gametogenesis
The ampulla is the widest segment of the fallopian tube and is the most common site for fertilization.
