This category focuses on the organs and processes involved in male reproduction, including sperm production (spermatogenesis), hormone secretion, and the transport of gametes.
Sertoli cells secrete Anti-Müllerian Hormone (AMH) during fetal development, leading to regression of Müllerian ducts in males.

Serum FSH levels, particularly measured on day 3 of the menstrual cycle, are commonly used to assess ovarian reserve.

The blood-placental barrier, primarily formed by trophoblast layers, prevents direct mixing of maternal and fetal blood while permitting the exchange of nutrients, gases, and wastes.

Luteinizing hormone (LH) stimulates Leydig cells in the testes to produce testosterone.

ICSI is a technique where a single sperm is injected directly into an oocyte, widely used to overcome severe male infertility.

Sperm are produced in the seminiferous tubules of the testes.

The epididymis is the site where sperm mature and are stored until ejaculation.

Androgens, including testosterone, are mainly produced by Leydig cells located in the interstitial tissue of the testes.

Maternal cardiac output increases during pregnancy due to increased blood volume and heart rate to meet the metabolic demands of both mother and fetus.
Ref: NCERT Class 12 Biology Chapter 2: Human Reproduction Male Reproductive System
Barrier methods, such as condoms, physically block sperm from entering the female reproductive tract and reaching the ovum.
